Question

Briefly explain the structure and function of heart.

Answer 1

The mammalian heart consists of four major parts and they are right and left atria just above the right and left ventricles. The right atrium connects to the right ventricle and the left atrium connects to the left ventricle. The tricuspid and the bicuspid valve stops the backflow of blood.

Answer 2

Answer:

Heart plays a very important role in the supply of oxygenated blood to different parts of the body. Deoxygenated blood is collected from various parts of the body and is transferred to the heart. The blood enters the heart through the pulmonary valve and enters the right atrium, then it goes to the right ventricle through the tricuspid valve. From here the blood then goes to the lungs for oxygenation. Oxygenated blood is then brought back to the heart with the help of pulmonary veins and enters the left atrium. The blood then goes to the left ventricle through the bicuspid valve and then transferred to the aorta through the aortic valve for further circulation of blood to different parts of the body.

The heart blood flow diagram (flowchart) given below will help you to understand the pathway of blood through the heart.Initial five points denotes impure or deoxygenated blood and the last five points denotes pure or oxygenated blood.
