ANATOMY

Detailed explanation-1: -Inferior vena cava: Receives blood from the lower extremities, pelvis and abdomen, and delivers blood into the right atrium. 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.

Detailed explanation-2: -The right ventricle (RV) pumps oxygen-poor blood through the pulmonary valve (PV) into the main pulmonary artery (MPA). From there, the blood flows through the right and left pulmonary arteries into the lungs.

Detailed explanation-3: -The right ventricle is the chamber within the heart that is responsible for pumping oxygen-depleted blood to the lungs.

Detailed explanation-4: -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.

Detailed explanation-5: -Right ventricle (VEN-trih-kul): one of the four chambers of the heart. The right ventricle pumps blood low in oxygen to the lungs. In the lungs, the blood then gets a “refill” of oxygen.
