What is the function of the right ventricle?

The function of the right ventricle is to pump oxygen-poor blood to the lungs. This is a critical part of the circulatory system's process of oxygenation. After the body has utilized the oxygen in the blood, the deoxygenated blood returns to the right atrium and then flows into the right ventricle. From there, it is pumped through the pulmonary arteries to the lungs, where carbon dioxide is exchanged for oxygen. This process is essential for replenishing the blood's oxygen levels, enabling it to carry oxygen to the body's tissues effectively.

The other options pertain to different functions or parts of the heart. The left ventricle is responsible for pumping oxygen-rich blood to the body, while the right atrium receives oxygen-poor blood from the body, not the right ventricle. Additionally, the heart does not store blood; its primary role is to pump blood throughout the body. Understanding the specific roles of each chamber of the heart helps in comprehending how the circulatory system operates efficiently.
