MEDICAL PHYSIOLOGY

Detailed explanation-1: -Its primary function involves the exchange of gases across the alveolar membrane which ultimately supplies oxygenated blood to the rest of the body and eliminates carbon dioxide from the circulation. The bronchial circulation provides oxygenated blood to the lung parenchyma.

Detailed explanation-2: -In pulmonary circulation: The pulmonary artery is a big artery that comes from the heart. It splits into two main branches, and brings blood from the heart to the lungs. At the lungs, the blood picks up oxygen and drops off carbon dioxide.

Detailed explanation-3: -Veins. Oxygenated blood leaves the lungs through pulmonary veins, which return it to the left part of the heart, completing the pulmonary cycle. This blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle.

Detailed explanation-4: -Pulmonary circulation: It is the type of circulation where the unoxygenated and oxygenated blood is circulated in the lungs and heart, this occurs in the heart and lungs where pulmonary refers to lungs. This process mainly converts deoxygenated blood to oxygenated blood.
