Pulmonary Trunk Function

Pulmonary trunk. Each of these vessels has elastic walls similar to those of the aorta, though somewhat thinner, and they are considered to be arteries even though the blood they carry is not oxygenated. The trunk itself is relatively short and wide. The function of these vessels is to transmit oxygen-depleted, carbon dioxide-rich blood from…

Pulmonary trunk. The right ventricle must first pump the blood to force it through the pulmonary valve and into the pulmonary trunk, which is the only outlet from the right ventricle. From here, the blood travels through each of the pulmonary arteries to reach the corresponding lungs.

The pulmonary trunk and the left and right pulmonary arteries are relatively large arteries. They are each shaped like tubes with a lumen (the opening through which blood flows). The left and right pulmonary arteries send blood to the left and right lungs, respectively.
