The two types of Blood Circulation in humans are :
(a) Pulmonary Circulation : Pertains to the lungs where pulmonary artery arises from right ventricle, carry deoxygenated blood and enters the lungs, whereas pulmonary veins collect oxygenated blood from lungs and carry to left atrium of the heart.
(b) Systemic Circulation : Pertains to the major circulation in the body. It starts with aorta that arises from the left ventricle. The aorta arches back and continues as aorta. It sends arteries to various body parts and their tissues. From there the blood is collected by veins and poured back into the heart.
