The right ventricle is one of the four chambers of the heart, located on the lower right side. Its primary function is to pump deoxygenated blood to the lungs through the pulmonary artery. This process is essential for oxygenating the blood, allowing it to pick up oxygen and release carbon dioxide. The right ventricle receives blood from the right atrium, which collects blood returning from the body. Once filled, the right ventricle contracts, pushing the blood into the lungs. Proper functioning of the right ventricle is crucial for maintaining effective circulation and overall cardiovascular health.
