Detailed explanation-1: -The oxygen-poor blood enters the right atrium (RA), or the right upper chamber of the heart. From there, the blood flows through the tricuspid valve (TV) into the right ventricle (RV), or the right lower chamber of the heart.
Detailed explanation-2: -Oxygen-poor blood from the body enters your heart through two large veins called the superior and inferior vena cava. The blood enters the heart’s right atrium and is pumped to your right ventricle, which in turn pumps the blood to your lungs.
Detailed explanation-3: -Parts of the heart. Superior vena cava. This carries oxygen-poor blood from the upper part of the body to the right atrium.
Detailed explanation-4: -The oxygenated blood is brought back to the heart by the pulmonary veins which enter the left atrium. From the left atrium blood flows into the left ventricle. The left ventricle pumps the blood to the aorta which will distribute the oxygenated blood to all parts of the body.
