What are the functions of the right ventricle ?!


Question: .......................


Answers: .......................

The right ventricle is the pumping chamber for the pulmonary side of circulation. Deoxygenated blood flows to the right atrium from all the veins in the body and is directed through the right atrium into the right ventricle through the tricuspid valve. After blood is recieved into the right ventricle in diastole, the tricuspid valve closes and the right ventricle contracts in a period called systole. When the ventricle contracts, blood is directed out of the right ventricle through the pulmonic valve and into the main pulmonary artery (which is the only artery in the body that carries deoxygenated blood.) From the main pulmonary artery, blood flows into the left and right pulmonary arteries, becomes oxygenated through capillaries in the lungs, and into the pulmonary veins to the left side of the heart. After the oxygenated blood leaves the left side of the heart to flow systemically, the blood heads back into the veins and is brought back to the right atrium to start the whole process over again.

it would have taken you less time to google that and find your own answer than post it here.
