Detailed explanation-1: -Your superior vena cava is next to the right side of your sternum and goes into your right atrium, where all the oxygen-poor blood goes. Your inferior vena cava is a little longer. It starts where the right and left common iliac veins come together in your belly area and goes up into the right atrium of your heart.

Detailed explanation-2: -The IVC enters the right atrium of the heart after coursing through the diaphragm, entering the posterior inferior aspect of the atrium. The IVC enters the right atrium inferior to the entrance of the superior vena cava (SVC).

Detailed explanation-3: -Mitral valve connects your left atrium and left ventricle. Pulmonary valve connects your right ventricle and pulmonary arteries (arteries that carry blood to your lungs). Tricuspid valve connects your right atrium and right ventricle.

Detailed explanation-4: -Superior vena cava: This large vein delivers oxygen-poor blood from your upper body into your heart’s right atrium.

Detailed explanation-5: -vena cava, in air-breathing vertebrates, including humans, either of two major trunks, the anterior and posterior venae cavae, that deliver oxygen-depleted blood to the right side of the heart.
