There are two types of Circulation
Pulmonary circulation is a portion of circulation responsible for carrying deoxygenated blood away from the heart, to the lungs and then bringing oxygenated blood back to the heart.
Systemic circulation is another portion of circulation where the oxygenated blood is pumped from the heart to every organ and tissue in the body, and deoxygenated blood comes back again to the heart.
What helps in circulation?
Veins – It supplies deoxygenated blood to the heart via inferior and superior vena cava, eventually draining into the right atrium.
Capillaries – They are minuscule, tube-like vessels which form a network between the arteries and veins.
Arteries – These are muscular-walled tubes responsible for supplying oxygenated blood away from the heart to all other parts of the body.
