What Is Deoxygenated Blood?

Decent Essays

The heart is a muscular organ in charge of pumping blood to all parts of the body. As the heart contracts, the blood is forced out through blood vessels and begins to follow a specific pathway. The blood makes it way through pulmonary circulation (to the lungs) and then through systemic circulation (the rest of the body).
Deoxygenated blood enters the right atrium through the superior and inferior vena cava. It then is transported to the right ventricle through the right atrioventricular valve (tricuspid valve). The ventricles contract and the valve closes so that blood does not flow back into the atrium. As the right ventricle contracts, it forces the deoxygenated blood through the pulmonary semilunar valve and into the pulmonary artery.
