Question

what is the which the blood flows through during pulmonary circulation?

Answer 1

Answer:

Pulmonary circulation is the movement of blood from the heart to the lungs for oxygenation, then back to the heart again The oxygenated blood then leaves the lungs through pulmonary veins, which returns it to the left atrium, completing the pulmonary circuit. As the pulmonary circuit ends, the systemic circuit begins.

Answer 2

Pulmonary circulation transports oxygen-poor blood from the right ventricle to the lungs, where blood picks up a new blood supply. Then it returns the oxygen-rich blood to the left atrium
