Explanation:
Detailed explanation-1: -Blood first enters the heart’s right atrium. A muscle contraction forces the blood through the tricuspid valve into the right ventricle. When the right ventricle contracts, blood is forced through the pulmonary semilunar valve into the pulmonary artery. Then it travels to the lungs.
Detailed explanation-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.
Detailed explanation-3: -Right ventricle: Receives blood from the right atrium; pumps blood into the pulmonary artery.
