Answer: There are two main types of circulation; Pulmonary Circulation, and Systemic Circulation.
Pulmonary Circulation moves blood between the heart and lungs, whereas systemic circulation moves blood between the heart and the rest of the body.
Explanation: Pulmonary Circulation takes deoxygenated blood (blood with no oxygen in it) to the lungs where it absorbs oxygen, and spits out Carbon dioxide, after it's done oxygenating itself (getting oxygen into itself) it heads back to the heart.
Pulmonary Circulation is important because it oxygenates blood and eliminates carbon dioxide from the circulation.
systemic circulation delivers oxygen and vital nutrients to our cells, and picks up waste products and carbon dioxide. In systemic circulation, oxygenated blood goes through the left ventricle of the heart, through your arteries, and then to your capillaries in your body tissue.
The systemic circulation is vital to survive, because it provides the functional blood supply to all body tissue.
I hope this helps! Also, there is a show called 'Cells At Work" on netflix (it might be on youtub in english too), It is an anime about cells, and blood circulation and stuff. It's not stupiid like other anime (no offence if your an anime lover) It's really educational.
Anyway, I hope this helps!! Have an amazing day!!
