The body circulatory system is made of two paths namely pulmonary circulation which is the circuit or path that goes through the lungs where blood is oxygenated, and systemic circulation which is the circuit or path that goes to all the rest of the body to provide it with oxygenated blood.
Pulmonary circulation is the movement of blood from the heart to the lungs then back to heart again. Systemic circulation is the movement of blood from the heart to and through the rest of the body to provide oxygen and nutrients, bringing the deoxygenated blood back to the heart again.
