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: -The left ventricle (LV) pumps the oxygen-rich blood through the aortic valve (AoV) into the aorta (Ao), the main artery that takes oxygen-rich blood out to the rest of the body.

Detailed explanation-3: -Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.

Detailed explanation-4: -The blood leaving the heart and getting distributed to all other body parts is usually oxygenated, while the blood coming from the body tissue and back to the heart is deoxygenated. Systemic circulation is also referred to as the systemic circuit.

Detailed explanation-5: -The cardiovascular system is composed of two circulatory paths: pulmonary circulation, the circuit through the lungs where blood is oxygenated, and systemic circulation, the circuit through the rest of the body to provide oxygenated blood.
