Question

Why do you need two different circuits of blood vessels in your body​

Answer 1

The blood vessels of the body are functionally divided into two distinctive circuits: pulmonary circuit and systemic circuit. The pump for the pulmonary circuit, which circulates blood through the lungs, is the right ventricle. The left ventricle is the pump for the systemic circuit, which provides the blood supply for the tissue cells of the body.

Answer 2

You need 2 circuits of blood vessels in your body so that oxygenated and deoxygenated blood don't mix.

Step-by-step explanation:

Arteries carry oxygen-rich blood from your heart to the rest of your body so that you can function. The oxygen is used, and the blood is taken back to the heart through veins to start the cycle over. I hope that answers your question!
