Deoxygenated blood from the right ventricle of the heart is pumped into which structures?

Deoxygenated blood from the right ventricle is pumped into the pulmonary trunk and pulmonary arteries. This is crucial for the process of pulmonary circulation, which is responsible for transporting deoxygenated blood to the lungs for oxygenation.

The pulmonary trunk originates from the right ventricle and branches into the left and right pulmonary arteries, which take the deoxygenated blood to the corresponding lung where it can pick up oxygen and release carbon dioxide. This pathway is essential as it differentiates the pulmonary circulation from the systemic circulation.

The right atrium, pulmonary veins, and aorta are involved in different circulatory functions. The right atrium receives deoxygenated blood from the body, while the pulmonary veins carry oxygenated blood back to the left atrium from the lungs. The aorta carries oxygenated blood from the left ventricle to the rest of the body. Therefore, the structures involved in directly receiving and transporting deoxygenated blood from the right ventricle are indeed the pulmonary trunk and pulmonary arteries.
