ANATOMY

Detailed explanation-1: -The blood circulatory system (cardiovascular system) delivers nutrients and oxygen to all cells in the body. It consists of the heart and the blood vessels running through the entire body. The arteries carry blood away from the heart; the veins carry it back to the heart.

Detailed explanation-2: -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-3: -The pulmonary circulation is a short loop from the heart to the lungs and back again. The systemic circulation carries blood from the heart to all the other parts of the body and back again.

Detailed explanation-4: -The arteries (red) carry oxygen and nutrients away from your heart, to your body’s tissues. The veins (blue) take oxygen-poor blood back to the heart. Arteries begin with the aorta, the large artery leaving the heart.

Detailed explanation-5: -In the systemic loop, oxygenated blood is pumped from the left ventricle of the heart through the aorta, the largest artery in the body. The blood moves from the aorta through the systemic arteries, then to arterioles and capillary beds that supply body tissues.
