ANATOMY

Detailed explanation-1: -Systemic circulation carries oxygenated blood from the left ventricle, through the arteries, to the capillaries in the tissues of the body. From the tissue capillaries, the deoxygenated blood returns through a system of veins to the right atrium of the heart.

Detailed explanation-2: -Veins bring blood to the right side of your heart. Pulmonary arteries carry the blood to your lungs, where it receives oxygen. Pulmonary veins move the blood oxygen-rich blood to the left side of your heart.

Detailed explanation-3: -The heart can very often be looked upon as two separate pumps. The left side receives oxygenated blood from the lungs and pumps this blood out through the aorta to all parts of the body. Therefore, the left side is considered a part of the systemic circuit.

Detailed explanation-4: -Arteries carry blood away from the heart and veins carry blood back to the heart.
