What side is Your Heart on?

What Side is Your Heart On? – You may be surprised, however, to learn which side your heart is on because it is on neither the left side or the right side of your chest. Your heart is actually located in the center of your chest, slightly to the left-hand side.

So why do many people assume that their heart is on the left side of the chest? According to Dr. Matthew Hoffman on WebMD, your heart is found right behind your breastbone (sternum).1 Your heart is about the size of a clenched fist and about 2/3 of your heart is found on the left side of the body and 1/3 is on the right side.

The base of the heart has an apex which points to the left side. Each side of the heart has 2 chambers called the atrium and the ventricle. Dr. Hoffman says that the left side of the heart is the strongest and it’s this side that pumps oxygen-rich blood to the body.

Where is the human heart located in the body?

Position of Heart in Human Body – The human heart is located between the lungs in the thoracic cavity, slightly towards the left of the sternum (breastbone). It is derived from the embryonic mesodermal germ layer. The function of the heart in any organism is to maintain a constant flow of blood throughout the body.

One of the primary functions of the human heart is to pump blood throughout the body. Blood delivers oxygen, hormones, glucose and other components to various parts of the body, including the human heart. The heart also ensures that adequate blood pressure is maintained in the body

There are two types of circulation within the body, namely pulmonary circulation and systemic circulation. Heart In Human Body Which Side Pulmonary circulation (blue) and Systemic circulation (red)

What makes up the right and left heart?

Valves – Valves are flaps of fibrous tissues located in the cardiac chambers between the veins. They ensure that the blood flows in a single direction (unidirectional). Flaps also prevent the blood from flowing backwards. Based on their function, valves are of two types:

Atrioventricular valves are between ventricles and atria. The valve between the right ventricle and right atrium is the tricuspid valve, and the one which is found between the left ventricle and left atrium is known as the mitral valve. Semilunar valves are located between the left ventricle and the aorta. It is also found between the pulmonary artery and the right ventricle.

The heart pumps around 6,000-7,500 litres of blood in a day throughout the body. The heart is situated at the centre of the chest and points slightly towards the left. On average, the heart beats about 100,000 times a day, i.e., around 3 billion beats in a lifetime. The average male heart weighs around 280 to 340 grams (10 to 12 ounces). In females, it weighs around 230 to 280 grams (8 to 10 ounces). An adult’s heart beats about 60 to 100 times per minute, and a newborn baby’s heart beats at a faster pace than an adult which is about 90 to 190 beats per minute.

The system then brings oxygenated blood back to the heart to be pumped throughout the body.

  • In systemic circulation, the heart pumps the oxygenated blood through the arteries to every organ and tissue in the body, and then back again to the heart through a system of veins.
  • The heart is a muscle, and it needs a constant supply of oxygenated blood to survive and work effectively.
  • This is where coronary circulation fulfils this function through a network of arteries and veins in the heart.

The coronary arteries supply oxygenated blood to the heart, and the cardiac veins drain the blood once it has been deoxygenated by the tissues of the heart. The human heart is divided into four chambers, namely two ventricles and two atria. The ventricles are the chambers that pump blood and atrium are the chambers that receive the blood.

The pericardium is a fibrous membrane that envelops the heart. It also serves a protective function by producing a serous fluid, which lubricates the heart and prevents friction between the surrounding organs. Furthermore, the pericardium also holds the heart in its position and provides a hollow space for the heart to expand and contract. The heart wall is made up of 3 layers, namely:

Epicardium – This is the outermost layer of the heart. It is composed of a thin layer of membrane that protects and lubricates the outer section. Myocardium – This is a layer of muscle tissue that constitutes the middle layer wall of the heart. It is responsible for the heart’s “pumping” action. Endocardium – The innermost layer that lines the inner heart chambers and covers the heart valves. Prevents blood from sticking, thereby avoiding the formation of fatal blood clots.

The blood vessels comprise:

Veins – It supplies deoxygenated blood to the heart via inferior and superior vena cava, eventually draining into the right atrium. Capillaries – They are minuscule, tube-like vessels which form a network between the arteries and veins. Arteries – These are muscular-walled tubes responsible for supplying oxygenated blood away from the heart to all other parts of the body.

Valves are flaps of tissues that are present in cardiac chambers between the veins. They prevent the backflow of blood. Examples include the atrioventricular valves, tricuspid valves, mitral valves and the semilunar valves. Myocardial infarction is a serious medical condition where the blood flow to the heart is reduced or entirely stopped.

What are the parts of the heart and their functions?

  • Parts of the heart: the cavities. There are numerous parts of the heart,but it’s important to know that they all work together in a coordinated fashion.
  • Other parts of the heart : the valves. The heart valves are the structures mentioned above and are located at the entrance and exit of the cavities.

What are the parts and functions of the human heart?

  • Arteries carry oxygen-rich blood from your heart to your body’s tissues. The exception is your pulmonary arteries,which go to your lungs.
  • Veins carry oxygen-poor blood back to your heart.
  • Capillaries are small blood vessels where your body exchanges oxygen-rich and oxygen-poor blood.

Is heart on left side?

An anomaly – “During the scan, I found transposition of the organs. The liver and gallbladder, normally located on the right side, were seen on the left side of the abdomen. The heart was located on the right side. The condition is called Situs Inversus with Dextrocardia,” said Dr Ahuja, specialist radiologist at Medeor Hospital, Dubai.
