MICROANATOMY

Detailed explanation-1: -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-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 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-4: -There are two main circulatory routes: pulmonary and systemic. The pulmonary circulation forms a closed circuit between the heart and the lungs, while the systemic circulation supplies oxygenated blood to and returning deoxygenated blood from the tissues of the body.

Detailed explanation-5: -Systemic circulation refers to the circulation of blood in which oxygenated blood is pumped from the heart to the body and deoxygenated blood is returned back to the heart. Systemic circulation occurs between the heart and the entire body.
