Question: Describe the transport of gases in a pulmonary circuit?
The transport of gases in a pulmonary circuit is the process of exchanging oxygen and carbon dioxide between the blood and the lungs. The pulmonary circuit consists of two main parts: the pulmonary arteries, which carry deoxygenated blood from the right ventricle of the heart to the lungs, and the pulmonary veins, which carry oxygenated blood from the lungs to the left atrium of the heart. The exchange of gases occurs in the alveoli, which are tiny air sacs in the lungs that are surrounded by capillaries. Oxygen diffuses from the alveoli into the blood, while carbon dioxide diffuses from the blood into the alveoli. The oxygenated blood then returns to the heart through the pulmonary veins, while the deoxygenated blood is expelled from the lungs through the pulmonary arteries.
