Question

describe the transportation of blood by heart in our body! class 10✨✨​

Answer 1

Answer:

Blood comes into the right atrium from the body, moves into the right ventricle and is pushed into the pulmonary arteries in the lungs. After picking up oxygen, the blood travels back to the heart through the pulmonary veins into the left atrium, to the left ventricle and out to the body's tissues through the aorta.

Answer 2

Answer:

The heart beats all the time throughout the life of an individual. Heart beat is the rhythmic contraction (systole) and relaxation (diastole) of human muscles. The rate of heart beat in a human adult is 72 times per minute. Pulmonary vein carries oxygenated blood from the lungs. Oxygenated blood enters the left atrium of the heart when the muscles of atria are relaxed. The atria then contracts, while the ventricles relax so that the blood is transferred to the left ventricle. When the muscular ventricles contract, oxygenated blood is poured into the largest artery of the body, called aorta. Then oxygen is transported to all parts of the body.

Large veins called vena cava collect deoxygenated blood from various parts of the body and pour it into the right atrium, as it relaxes. As the right atrium contracts, the deoxygenated blood is transferred to the right ventricle, which in turn pumps it to the lungs for oxygenation. Pulmonary artery carried blood from heart to the lungs.
