Detailed explanation-1: -Pulmonary circulation includes a vast network of arteries, veins, and lymphatics that function to exchange blood and other tissue fluids between the heart, the lungs, and back. They are designed to perform certain specific functions that are unique to the pulmonary circulation, such as ventilation and gas exchange.

Detailed explanation-2: -Pulmonary circulation transports oxygen-poor blood from the right ventricle to the lungs, where blood picks up a new blood supply. Then it returns the oxygen-rich blood to the left atrium.

Detailed explanation-3: -Blood comes into the right atrium from the body, moves into the right ventricle and is pushed into the pulmonary arteries in the lungs. After picking up oxygen, the blood travels back to the heart through the pulmonary veins into the left atrium, to the left ventricle and out to the body’s tissues through the aorta.

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.
