MICROANATOMY

Detailed explanation-1: -The pulmonary artery carries oxygen-poor blood from the right ventricle into the lungs, where oxygen enters the bloodstream. The pulmonary veins bring oxygen-rich blood to the left atrium. The aorta carries oxygen-rich blood to the body from the left ventricle.

Detailed explanation-2: -In the systemic circulation, the left ventricle pumps oxygen-rich blood into the main artery (aorta).

Detailed explanation-3: -The systemic circulation provides the functional blood supply to all body tissue. It carries oxygen and nutrients to the cells and picks up carbon dioxide and waste products. Systemic circulation carries oxygenated blood from the left ventricle, through the arteries, to the capillaries in the tissues of the body.

Detailed explanation-4: -Your pulmonary veins are the only veins in your body that carry oxygen-rich blood. All your other veins carry oxygen-poor blood. Similarly, your pulmonary arteries are the only arteries that carry oxygen-poor blood. All the rest of your arteries carry oxygen-rich blood.

Detailed explanation-5: -Pulmonary veins: Carry oxygen-rich blood from your lungs to your heart. All of your pulmonary veins (usually four) directly empty into your heart’s left atrium. Systemic circuit. Sends blood between your heart and the rest of your body.
