Detailed explanation-1: -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-2: -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. The blood then returns to the heart through the pulmonary veins.
Detailed explanation-3: -The Pulmonary circuit receives blood from body tissues and circulates it through the lungs, whereas the systemic circuit receives blood from pulmonary veins and pumps to the aorta, which spreads the oxygenated blood throughout the body.
Detailed explanation-4: -The pulmonary trunk splits into the right and left pulmonary arteries. These arteries transport the deoxygenated blood to arterioles and capillary beds in the lungs. There, carbon dioxide is released and oxygen is absorbed. Oxygenated blood then passes from the capillary beds through venules into the pulmonary veins.
