Question: Describe the transport of gases in a pulmonary circuit?
The transport of gases in a pulmonary circuit is a fascinating process that involves the exchange of 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 back to the left atrium of the heart. The gas exchange occurs in tiny air sacs called alveoli, where oxygen diffuses from the air into the blood, and carbon dioxide diffuses from the blood into the air. This way, the blood becomes enriched with oxygen and depleted of carbon dioxide, which are essential for cellular respiration and metabolism. The transport of gases in a pulmonary circuit is a vital function that enables us to breathe and live!
