NEET PG DENTAL EXAM

Detailed explanation-1: -The two largest veins in the body, the superior and inferior vena cava, bring the oxygen-poor (blue) blood to the heart into the right atrium. This oxygen-poor blood then passes through the tricuspid valve into the right ventricle.

Detailed explanation-2: -Both the superior vena cava and inferior vena cava empty blood into the right atrium. 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.

Detailed explanation-3: -What does the vena cava do? Your superior vena cava and inferior vena cava have the important function of carrying oxygen-poor blood to your heart’s right atrium, where it moves into your right ventricle and then to your lungs (through your pulmonary artery) to trade in carbon dioxide for oxygen.

Detailed explanation-4: -Oxygen-poor blood from all over your body enters your right atrium through two large veins, your inferior vena cava and superior vena cava.
