After being used by the major organs of the body, deoxygenated blood is transportedback to the right side of the heart by two large veins known as theand enters the, quickly passing by the openvalve, where blood then enters and fills thechamber.After filling, the cardiomyocytes contract, produce force on the blood and push openthevalve and allow blood to exit into theBlood now enters the circulation of the lung for gas exchange to occur. Onceoxygenated, blood returns to the heart from the lungs by way of four large vesselscalled the, blood then moves into theandpast the openvalve filling thechamber.From here, oxygenated blood is pushed past thevalve and intothewhere blood is pumped into the systemic circuit.

Sagot :

Deoxygenated blood is transported back to the heart by the superior and inferior vena cava, it enters the right atrium, and it passes the opened tricuspid atrioventricular valve to the right ventricle.

The cardiomyocytes of the right ventricle contract and push the blood through the pulmonary semilunar valves to the pulmonary arteries. The blood flows through the pulmonary system, where the gases are exchanged, and the blood is oxygenated.

Then the blood returns to the heart through the pulmonary veins to the left atrium and past the bicuspid atrioventricular valve to the left ventricle.

When the left ventricle contracts, the blood is pushed through the aortic semilunar valves into the aorta where it enters the systemic circulation.
