उत्तर
Flow of blood through heart -
-
Deoxygenated blood from different organs comes to the right atrium through the vena cava.
-
From the right atrium, blood goes to the right ventricle. The tricuspid valve between the right atrium and right ventricle prevents the backflow of blood.
- From the right ventricle, blood goes to the lungs through the pulmonary artery. Inside the lungs, carbon dioxide is removed from the blood and oxygen enters the blood.
- From the lungs, blood goes to the left atrium through the pulmonary vein.
- From the left atrium, blood goes to the left ventricle.
- From the left ventricle, blood is pumped into the aorta so that it can be supplied to different organs.
