The pulmonary trunk is a blood vessel which divides to form the right and left pulmonary arteries.At the base of this trunk is a pulmonary semilunar valve that is made up of three leaflets or cusps.he pulmonary trunk is a blood vessel which divides to form the right and left pulmonary arteries.
The pulmonary arteries carry blood to smaller arterioles and on to the vast capillary beds of the lungs where carbon dioxide is released and oxygen is obtained from the air in the alveoli of the lungs. These capillaries converge into larger venules, which further converge to form the left and right pulmonary veins.he pulmonary arteries and pulmonary veins provide vital but short distance blood flow between the heart and the lungs. Exiting the heart from the right ventricle, deoxygenated blood flows into the large pulmonary trunk before splitting at the left and right pulmonary arteries.
