Question

Explain the flow of blood in heart. class 10

Answer 1

hola there
first blood enters the heart through two large veins I.e
inferior and superior vena cava emptying oxygen poor blood from the body into the right atrium of the heart As the atrium contracts blood flows from your right atrium into your right ventricle through the open tricuspid valve hope you understand

$\large{\underline{\underline{\red{\sf{ Flow\:of\:blood\:in\:human\:Heart:- }}}}}$

The heart beats all the time throughout the life of an individual . Heartbeat is a rhythmic contraction and relaxation of the heart muscle. Pulmonary vein carries oxygenated blood from the lungs. Oxygenated blood enters the left atrium of the heart when the muscles of the atria are relaxed. In turn when the atrium contracts, the ventricle relax and the blood is transferred to the left ventricle. In turn when the ventricles contract oxygenated blood is transferred into Aorta , largest artery of the body . And hence oxygen is transferred to all the body.

Vena Cava collect deoxygenated blood from various body parts and transfer it into the right atrium when it relaxes. As right atrium contract the deoxygenated blood is transferred to the right ventricle which in turn it into the lungs for oxygenation . Pulmonary artery carries blood from heart to the lungs.

In human blood flows twice to the heart and thus , it is called double circulation.
