inferior vena cava delivers deoxygenated blood to the aorta chamber of the heart.
inferior vena cava delivers deoxygenated blood to which chamber of the heart?
aorta
the right heart collects deoxygenated blood from two large veins, the superior and inferior venae cavae. blood collects in the right and left atrium continuously. the superior vena cava drains blood from above the diaphragm and empties into the upper back part of the right atrium. the inferior vena cava drains the blood from below the diaphragm and empties into the back part of the atrium below the opening for the superior vena cava. immediately above and to the middle of the opening of the inferior vena cava is the opening of the thin-walled coronary sinus. additionally, the coronary sinus returns deoxygenated blood from the myocardium to the right atrium. the blood collects in the right atrium. when the right atrium contracts, the blood is pumped through the tricuspid valve into the right ventricle. as the right ventricle contracts, the tricuspid valve closes and the blood is pumped into the pulmonary trunk through the pulmonary valve. the pulmonary trunk divides into pulmonary arteries and progressively smaller arteries throughout the lungs, until it reaches capillaries. as these pass by alveoli carbon dioxide is exchanged for oxygen. this happens through the passive process of diffusion.
heart
the inferior vena cava is the lower ("inferior") of the two venae cavae, the two large veins that carry deoxygenated blood from the body to the right auricle of the heart: the inferior vena cava carries blood from the lower half of the body whilst the superior vena cava carries blood from the upper half of the body. together, the venae cavae (in addition to the coronary sinus, which carries blood from the muscle of the heart itself) form the venous counterparts of the aorta.
