Q.27. What is the function of heart in human body , explain through schamatic diagram of circulation.
Answers
Explanation:
The four main functions of the heart are: Pumping oxygenated blood to the other body parts. Pumping hormones and other vital substances to different parts of the body. Receiving deoxygenated blood and carrying metabolic waste products from the body and pumping it to the lungs for oxygenation.
Answer:
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.
