Detailed explanation-1: -Ans : Pulmonary circulation is the process in which the deoxygenated blood is carried away in pulmonary arteries from the heart to the lungs. This process cause oxygenation of the blood, and then this oxygenated blood is sent back to the heart.

Detailed explanation-2: -In amphibians, reptiles, birds, and mammals, blood flow is directed in two circuits: one through the lungs and back to the heart, which is called pulmonary circulation, and the other throughout the rest of the body and its organs including the brain (systemic circulation).

Detailed explanation-3: -The circulatory system (cardiovascular system) pumps blood from the heart to the lungs to get oxygen. The heart then sends oxygenated blood through arteries to the rest of the body. The veins carry oxygen-poor blood back to the heart to start the circulation process over.

Detailed explanation-4: -Pulmonary circuit: Circulation of blood between heart and other body parts.

Detailed explanation-5: -In amphibians, reptiles, birds, and mammals, blood flow is directed in two circuits: one through the lungs and back to the heart, which is called pulmonary circulation, and the other throughout the rest of the body and its organs including the brain (systemic circulation).
