Explanation:
Detailed explanation-1: -Oxygen-poor blood returns from the body to the heart through the superior vena cava (SVC) and inferior vena cava (IVC), the two main veins that bring blood back to the heart. The oxygen-poor blood enters the right atrium (RA), or the right upper chamber of the heart.
Detailed explanation-2: -Right ventricle: Receives blood from the right atrium; pumps blood into the pulmonary artery. 6. Pulmonary valve: Allows blood to pass into the pulmonary arteries; prevents blood from flowing back into the right ventricle.
