Question

37 how many circuits or loops does the human cardiovascular system have? multiple choice one: between the heart/body/lungs in one circle two: one between heart/brain and one between heart/body two: one between heart/lungs and one between heart/body three: one between heart/brain, one between heart/lungs, and one between heart/body

Explanation:

The human cardiovascular system has two main loops. The pulmonary circuit (heart/lungs) is for gas exchange (oxygenating blood and removing carbon dioxide). The systemic circuit (heart/body) distributes oxygenated blood to the body's tissues and organs and collects de - oxygenated blood. There is no specific "heart/brain" loop as the brain is part of the systemic circulation.

Answer:

Two: one between heart/lungs and one between heart/body.
