MEDICAL PHYSIOLOGY

Detailed explanation-1: -Oxygen-poor blood from all over your body enters your right atrium through two large veins, your inferior vena cava and superior vena cava. Your tricuspid valve opens to let blood travel from your right atrium to your right ventricle.

Detailed explanation-2: -The blood vessels include the superior and inferior vena cava. These bring blood from the body to the right atrium.

Detailed explanation-3: -Right atrium: Receives blood returning to the heart from the superior and inferior vena cava; transmits blood to the right ventricle, which pumps blood to the lungs for oxygenation. 4.

Detailed explanation-4: -The heart consists of four chambers in which blood flows. Blood enters the right atrium and passes through the right ventricle. The right ventricle pumps the blood to the lungs where it becomes oxygenated. The oxygenated blood is brought back to the heart by the pulmonary veins which enter the left atrium.
