Which chamber of the heart sends deoxygenated blood to the lungs?

The right ventricle is the chamber of the heart responsible for sending deoxygenated blood to the lungs. This process occurs through the pulmonary arteries. When blood returns to the heart from the body, it is deoxygenated and enters the right atrium, then moves into the right ventricle. Upon contraction, the right ventricle expels the deoxygenated blood into the pulmonary circulation, where it travels to the lungs for oxygenation.

Understanding the flow of blood through the heart is crucial in recognizing this function. The left atrium and left ventricle deal with oxygenated blood, which is why they are not involved in sending deoxygenated blood to the lungs. The left atrium receives oxygen-rich blood from the lungs, while the left ventricle pumps this oxygenated blood out to the body. The right atrium receives deoxygenated blood from the body but does not directly send it to the lungs; instead, it is the right ventricle that performs this critical function.
