Final answer:
Option 2). The right ventricle is the chamber from which deoxygenated blood is pumped out of the heart towards the lungs.
Step-by-step explanation:
The right ventricle of the heart pumps out deoxygenated blood. This blood, which is low in oxygen, is first taken in by the right atrium and pumped into the right ventricle. The blood is then sent by the right ventricle through the pulmonary artery to the lungs in order to receive oxygen. The heart's atriums and ventricles are all vital to blood circulation. Blood that is high in oxygen is handled by the left atrium and ventricle, whereas blood that is low in oxygen is handled by the right. The architecture of the heart promotes effective blood flow along the pulmonary and systemic circuits.
