what is the main function of the pulmonary circuit?
Pulmonary Circuit. Pulmonary circuit mainly composed of pulmonary arteries, which carry blood from the right ventricle to lungs, pulmonary capillaries where the exchange of gas takes place, and pulmonary veins, which carry blood to the left atrium. This circuit starts at the right ventricle and ends at the left atrium.
The pulmonary artery carries deoxygenated blood from the right ventricle to the lungs. The blood here passes through capillaries adjacent to alveoli and becomes oxygenated as part of the process of respiration. In contrast to the pulmonary arteries, the bronchial arteries supply nutrition to the lungs themselves.
