ANATOMY

Detailed explanation-1: -The pulmonary circulation is a short loop from the heart to the lungs and back again. The systemic circulation carries blood from the heart to all the other parts of the body and back again.

Detailed explanation-2: -Pulmonary circulation moves blood between the heart and the lungs. It transports deoxygenated blood to the lungs to absorb oxygen and release carbon dioxide. The oxygenated blood then flows back to the heart. Systemic circulation moves blood between the heart and the rest of the body.

Detailed explanation-3: -Blood flows through the tricuspid valve into the right ventricle. It then flows through the pulmonic valve into the pulmonary artery before being delivered to the lungs. While in the lungs, blood diverges into the numerous pulmonary capillaries where it releases carbon dioxide and is replenished with oxygen.

Detailed explanation-4: -The blood enters the heart’s right atrium and is pumped to your right ventricle, which in turn pumps the blood to your lungs. The pulmonary artery then carries the oxygen-poor blood from your heart to the lungs.

Detailed explanation-5: -Answer and Explanation: The correct answer is E. The pulmonary pathway flows from the right ventricle through the pulmonary trunk to the lungs to pick up oxygenated blood. The oxygenated blood returns to the left atrium.
