Question

describe structure and function of heart ​

Answer 1

Answer:

▪ Structure of the Heart

➡️ The heart can be found at the center of the chest, underneath the sternum in a thoracic compartment. It is made up of four chambers and several valves that regulate the normal flow of blood within the body.

➡️ Two chambers called atria are located in the upper portion of the heart and receive oxygen-free blood. The valves that separate these chambers are called atrioventricular valves which is composed of the tricuspid valve on the left and the mitral valve on the right.

➡️ On the other hand, ventricles are chambers found on the lower portion of the heart; they pump oxygen-enriched blood into all organs of the body, reaching even the smallest cells. Similar to the atria, the ventricular chambers are also separated by valves. Collectively-termed as semilunar valves, these are comprised of the pulmonary and aortic valve.

▪ Its Function

➡️ Blood flows through your heart and lungs in four steps: The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle through the tricuspid valve. The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle through the mitral valve.

Answer 2

Answer:

here's the answer:-

• The heart is a large muscular pump and is divided into two halves - the right-hand side and the left-hand side. The right-hand side of the heart is responsible for pumping deoxygenated blood to the lungs. The left-hand side pumps oxygenated blood around the body.
• Function of our heart is to purify deoxygenated blood and pump it to all parts of the body with the help of blood vessels like capillaries etc.
