Download Article Download Article Every heart is made of two pumps: the right receives blood and pumps it to your lungs, while the left receives blood from the lungs and pumps it into the bloodstream. If you want to make a heart model and see this process in action, it’s pretty easy! Whether you want to get hands-on with some playdough or get a bit more complicated using a Styrofoam cup or pop bottle model, you’ll have fun and learn at the same time.
- 1 Create the heart using red playdough. Start by rolling a small red ball about 1 to 1.5 inches (2.5 to 3.8 cm) wide and thick. Now, lay a finger vertically down the middle and press down gently to create a small indent. Press down firmly on the top to create another more prominent indent as if it were an apple.
- Leave the left side of the top indent (the right ventricle) slightly taller than the right side (the left ventricle).
- Remember that the left side is actually the right ventricle and vice versa. If you get confused, imagine the heart inside your body!
- 2 Attach a small tube of red playdough to the top of the right ventricle. Roll a cylindrical piece of red playdough about 2 inches (5.1 cm) long to act as the aorta. Once you’re done, attach it to the top of the left bulge (right ventricle). Create a curve in the tube about 0.5 inches (1.3 cm) from the heart that runs down over the right bulge (left ventricle) and tails off to the right.
- Use a playdough knife to make a small incision into the end of the cylindrical piece to represent the center tubing of the aorta.
- 3 Connect a 1 ⁄ 2 inch (1.3 cm) tube vertically to the bottom of the heart. Right now, the top tube is the aorta extending from the top of the heart. Now, make a smaller tube piece about 1 ⁄ 2 inch (1.3 cm) long and connect it to the bottom of the heart—this is the bottom of the aorta.
- Make sure the small tube runs directly across from the top tube, as if both of them make one single piece running through the heart.
- 4 Attach 3 small 1 ⁄ 4 inch (0.64 cm) tubes to the aorta. Roll 3 small tubes to represent the arteries that extend from the aorta. Now, connect them to the top piece of the aorta.
- Create 3 small holes in the tips of the tubes using the tip of your playdough knife or a toothpick. These represent the circular inner tubing of the arteries.
- 5 Run a tube of blue playdough right across the aorta. Roll a tube of blue playdough about 1.5 inches (3.8 cm) long—slightly smaller than the aorta tube. This is your heart’s left vein. Now, connect one end to the base of the aorta extending from the top of the heart. Run it to the right horizontally over the portion of the aorta that extends to the right.
- If it’s easier, break the blue tube into 2 pieces and attach them individually. Start by running one from the bottom of the aorta up to the center of the heart, and the other extending from this point to the right over the remaining section of the aorta.
- 6 Attach another tube of blue playdough vertically to the left of the heart. This is the heart’s right vein. Start by rolling a tube of blue playdough about 3 inches (7.6 cm) long. Now, attach it to the back-left of the heart (the right ventricle) so that only the top and bottom of the tube are visible. Wrap the top of the tube over the heart and toward you.
- Create a small hole in the top tip of the tube using a playdough knife or toothpick. This represents the center tubing of the vein.
- 7 Add an artery to the top of each blue vein. Roll 2 small tubes of blue playdough for each artery. Now, attach them to the top about 1 ⁄ 2 inch (1.3 cm) from their tips.
- Create a small hole in each tip of the artery using your knife.
- 1 Fill 1 Styrofoam cup with water. The cup acts as the heart and the water is the blood. The size of the cup isn’t too important, as long as it can hold at least 1 cup (240 mL) of water. If you have something larger, go for it!
- You can use a beaker instead of a cup for similar results.
- Add a few drops of red food coloring for a nice effect!
- 2 Cut the neck of a large balloon off with scissors. Purchase some large balloons that are 11 to 12 inches (28 to 30 cm) in size when inflated. Take one and cut the neck at the region where it starts to widen into the body. Afterward, set the neck aside for later.
- Keep broken or uninflated balloons away from children under 8 years of age.
- 3 Stretch the balloon over the cup’s opening. Afterward, pull it down over the cup as tightly as possible. When you’re finished, the surface of the balloon should be as flat as possible.
- Discard any broken balloons as soon as possible.
- 4 Poke 2 holes into the balloon’s surface with a wooden skewer. Gently press down on the surface of the balloon with the sharp end of the skewer to create the holes. Try to make them roughly the size of your straws’ diameter or slightly smaller. Be sure to create each hole on opposite edges of the balloon about 1 inch (2.5 cm) apart.
- Purchase wooden skewers from big-box stores and home hardware stores.
- 5 Insert the long part of your 2 straws into the holes. Gently insert each one to avoid ripping the balloon. Be sure that the straws fit snugly into the holes so that no air escapes.
- If the holes are too big and air escapes, remove the balloon and repeat the last 3 steps.
- 6 Wrap the uncut part of the balloon neck onto a straw. Cover the tip of one of the straws with the neck so that no air can escape. After wrapping it around the straw, tape it to the straw to hold it in place.
- Use Scotch tape for the best results.
- 7 Pump the heart into a sink by pressing onto the balloon. Start by aiming the open straw into a sink, which will act as the body. Gently press one of your fingers down onto the center of the balloon, which acts as the heart. Each time you press down, the water—acting as the blood—from the cup is pumped through the straws and into the sink.
- The cut part of the balloon acts as a valve that stops the blood from moving back down the straw into the previous chamber.
- 8 Remove the balloon neck from the straw and press down on the balloon. After pumping the heart without a valve, nothing keeps the blood from moving down the straw. This prevents the blood from moving through the heart and into the body!
- Remember that the balloon neck is your heart’s valve. This example shows how 1 chamber of your heart works with its valve. But inside your body, there are 4 chambers and 4 valves!
- 1 Drill 2 holes into a bottle cap with an 11 ⁄ 32 inch (0.87 cm) drill bit. Standard straws usually have a diameter of about 0.36 inches (0.91 cm), which is roughly the size of a 11 ⁄ 32 inch (0.87 cm) drill bit. Attach the drill bit to your electric drill and create 2 holes in one of the caps about equal distance apart.
- Each hole should be big enough for your straws to slide through.
- Never use an electric drill without the help of an adult!
- 2 Drill 1 hole into another bottle cap with a 6 ⁄ 16 inch (0.95 cm) drill bit. The hole in the second cap should be smaller than the first 2 holes. Again, attach your bit and drill down into the cap while applying firm pressure.
- Always place the bottle caps onto a flat surface while drilling.
- 3 Mix 1 litre (0.26 US gal) of water and food coloring in your pitcher to create blood. Add a few drops of food coloring into a pitcher of water. Don’t worry about using an exact amount of food coloring—as long as you have something that looks bloody!
- Stir the food coloring into the pitcher using a straw.
- 4 Connect 2 straws and bend them to create two 90 degree angles. Pinch 1 straw at the end of the tip to make it smaller and insert it into the tip of the other straw. Adjust the bendable portion of the straws so each one is 90 degrees. Tape the straws together at the point where they connect.
- Keep the long portions of the straws parallel and facing downward.
- Repeat the above process with the remaining 2 straws.
- 5 Fill 2 of your pop bottles about 80 percent full with water. Carefully pour your red water into each of your bottles. Don’t worry about filling them exact—just try to leave about 1/3 of each empty.
- Remove the labels from your pop bottles if you haven’t already.
- 6 Align your 3 bottles in front of you and insert the final straw. Place your 2 bottles with blood in front of you in a straight horizontal line. Now, place the empty bottle to the right of them.
- Place your bottles on a clean, flat surface.
- 7 Slide 2 straws through 2 caps and attach them to the bottles with water. Start by sliding the long end of a straw through the bottle with 1 hole in it. Now, take the other long end and slide it through the cap with 2 holes. Attach the cap with 1 hole to the left bottle and the second cap with 2 holes to the middle bottle. Afterward, fasten the caps.
- Leave the third bottle empty.
- Carefully slide the long ends of the straws into each pop bottle before you attach the caps and take care not to bend them.
- 8 Attach the final 2 connected straws to the middle and right bottles. Insert one end of the final straw into the remaining hole on the middle bottle’s cap. Now, insert the remaining end into the empty bottle with no cap.
- Seal any open space between the holes and the straws with clay.
- 9 Label each bottle with masking tape. Attach a piece of tape to each bottle horizontally and label each one with a permanent marker. Mark the left bottle as the atrium of the heart, the second as the ventricle, and the third as the lungs (or body). Your fingers act as the heart’s valves.
- You can skip this step if you’d like, but it helps to better understand the function of each part of the model.
- 10 Squeeze the middle bottle and pinch the first straw connector. Pinch the left straw connector that runs between the left bottle (heart) and the middle bottle (ventricle). Now, squeeze the ventricle and watch the blood flow into the body! Afterward, let go of the left straw connector and pinch the right straw connector between the ventricle and the body while keeping the ventricle squeezed.
- Repeat this process to pump blood from the heart into the ventricle, and then distribute it into the body!
- When the blood in the heart is low, remove some from the body and distribute it back to the heart. Now, you can start the process over.

Can human have 2 hearts?
Can humans have two hearts? Doctor Who can function with two hearts, but can non-Time Lords do the same? Greg Foot finds out. B Being a Gallifreyan, Doctor Who has a binary vascular system, where the blood vessels lead to two hearts. If the Time Lord can function with two hearts, can humans do the same? Aside from conjoined twins, no human is born with two hearts.
But in the case of extreme heart disease, called cardiomyopathy, rather than receiving a donor heart and removing yours, doctors can graft a new heart on to your own to help share the work. This is more commonly known as a piggy-back heart. Some animals like the octopus have more than one heart. An octopus has one main, systemic heart that pumps blood to the whole of its body.
But it also has two additional hearts, responsible for pumping blood over each of its gills.

- Context.— Colors are important to all living organisms because they are crucial for camouflage and protection, metabolism, sexual behavior, and communication.
- Human organs obviously have color, but the underlying biologic processes that dictate the specific colors of organs and tissues are not completely understood.
A literature search on the determinants of color in human organs yielded scant information. Objectives.— To address 2 specific questions: (1) why do human organs have color, and (2) what gives normal and pathologic tissues their distinctive colors? Data Sources.— Endogenous colors are the result of complex biochemical reactions that produce biologic pigments: red-brown cytochromes and porphyrins (blood, liver, spleen, kidneys, striated muscle), brown-black melanins (skin, appendages, brain nuclei), dark-brown lipochromes (aging organs), and colors that result from tissue structure (tendons, aponeurosis, muscles).
- Yellow-orange carotenes that deposit in lipid-rich tissues are only produced by plants and are acquired from the diet.
- However, there is lack of information about the cause of color in other organs, such as the gray and white matter, neuroendocrine organs, and white tissues (epithelia, soft tissues).
Neoplastic tissues usually retain the color of their nonneoplastic counterpart. Conclusions.— Most available information on the function of pigments comes from studies in plants, microorganisms, cephalopods, and vertebrates, not humans. Biologic pigments have antioxidant and cytoprotective properties and should be considered as potential future therapies for disease and cancer.
- We discuss the bioproducts that may be responsible for organ coloration and invite pathologists and pathology residents to look at a “routine grossing day” with a different perspective.
- I want to know one thing.
- What is color?” —Pablo Picasso Nature delights us with a great variety of colors that result from the reflection of a particular wavelength of light from an object.
Colors are important to all biologic organisms (that is, microorganisms, plants, and animals) because they are crucial for camouflage and protection, metabolism, sexual behavior, and communication. In general, coloration of organisms results from the production of molecules derived from cyclic compounds.
- The human body and its organs have colors, that is, the liver is brown, the heart is red, bones are white, and so on.
- Although this is obvious and established, the reason why organs have a particular color is not completely understood.
- Pathologists, more than any other physicians, should be aware of the importance in recognizing normal and abnormal gross organ features—color being one of them—that translate into specific pathologic processes.
Because cells are microscopic and colorless as single units, they result in a given color only when they accumulate in millions. Unhealthy and/or neoplastic tissues usually retain the color of the cells from which they derive but may also exhibit completely different color characteristics.
We performed a literature search related to the biochemical source of coloration in human organs, and to our surprise, scant information is available. Because of this information gap, 2 fundamental questions were asked: why do human organs have color, and what gives normal and pathologic tissues their distinctive colors? The answers to these simple questions are elusive, even with the current revolutionary advances in molecular biology and biochemistry.
The biochemical processes related to pigment production in plants and animals could be an enormous resource to explain the color in human organs. Herein, we attempt to give a biochemical explanation for the basis of the color of human organs that, to our knowledge, is not currently available in the medical literature.
What is the pattern of heart?
How Does Blood Flow Through the Heart? – The right and left sides of the heart work together. The pattern described below is repeated over and over, causing blood to flow continuously to the heart, lungs, and body. Right side
Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium.As the atrium contracts, blood flows from your right atrium into your right ventricle through the open tricuspid valve.When the ventricle is full, the tricuspid valve shuts. This prevents blood from flowing backward into the atria while the ventricle contracts.As the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs where it is oxygenated.
The pulmonary vein empties oxygen-rich blood from the lungs into the left atrium.As the atrium contracts, blood flows from your left atrium into your left ventricle through the open mitral valve.When the ventricle is full, the mitral valve shuts. This prevents blood from flowing backward into the atrium while the ventricle contracts.As the ventricle contracts, blood leaves the heart through the aortic valve, into the aorta and to the body.
What 3 layers make up the heart?
Structure – The fibrous skeleton, cardiac muscle, and impulse conduction system constitute the basic framework of the heart. The base of the heart contains a highly dense structure known as the fibrous or cardiac skeleton. Functions of the fibrous skeleton include providing as a strong framework for cardiomyocytes, anchoring the valvular leaflets, and acting as electrical insulation separating the conduction in the atria and ventricles.
The wall of the heart separates into the following layers: epicardium, myocardium, and endocardium. These three layers of the heart are embryologically equivalent to the three layers of blood vessels: tunica adventitia, tunica media, and tunica intima, respectively. A double-layer, fluid-filled sac known as the pericardium, surrounds the heart.
The two layers of the pericardium are called the outer fibrous/parietal pericardium and the inner serous/visceral pericardium. The epicardium constitutes the visceral pericardium, underlying fibro-elastic connective tissue, and adipose tissue. Coronary arteries and veins, lymphatic vessels and nerves run below the epicardium.
- The endocardium is composed of the endothelium and the subendothelial connective tissue layer.
- The subendocardium is found between the endocardium and myocardium and contains the impulse-conducting system.
- The impulse conducting system has specialized cardiac cells for the conduction of electrical impulses throughout the heart.
Electrical impulses initiate at the sinoatrial (SA) node, situated at the junction of the superior vena cava and right atrium. These impulses travel throughout the atria until it reaches the atrioventricular (AV) node; located between the interatrial and interventricular septum.
As the fibers travel inferiorly, it penetrates the central fibrous body of the cardiac skeleton to form the bundle of His. These fibers are the Purkinje fibers after they divide within the interventricular septum and branch into the ventricles. Valves are an important component of the heart. Not only do they act as an exit gate, but they also prevent backflow into the chamber.
The aortic valve, separating the aorta from the left ventricle, and the pulmonic valve, separating the pulmonary artery from the right ventricle, are known as semilunar valves. The two atrioventricular (AV) valves are the tricuspid and mitral valves. The tricuspid valve marks the separation between the right atrium and right ventricle while the mitral valve separates the left atrium from the left ventricle.
How does a heart pump model work?
The Heart Science – The pumping you do on the balloon mimics how the heart pumps in our bodies. The balloon on the straw works like the valves on the heart. It opens when you push down on the pump and closes as you release. This is what lets the blood flow up through the open straw, but like in the body, it prevents backflow of blood.
Which machine is used for pumping heart?
During the procedure – A team of doctors and nurses works together to perform VAD surgery. Members of this team will include:
Heart surgeons (cardiovascular surgeons) Nurses trained in surgery (surgical nurses) Doctors trained in giving medication to make you sleep during surgery (anesthesiologists)
Getting a ventricular assist device (VAD) often requires open-heart surgery. VAD surgery usually takes three or more hours. You can expect the following:
You’ll receive medicines through an IV to make you sleepy and pain-free during the surgery. You’ll be connected to a machine that helps you breathe (ventilator) during your surgery. Your heart may be stopped using medications during the surgery. If so, you’ll be connected to a heart-lung bypass machine, which keeps oxygen-rich blood flowing through your body during surgery.
To implant an LVAD, the surgeon makes an incision down the center of the chest. The surgeon then separates the chest bone (sternum) to better view the heart and place the device. An LVAD has several parts. The main pump is inserted into the tip of the heart.
