lungs to pulmonary veins to left atria to mitral valve to left ventricle to aortic valve to aorta to the rest of the body, then the blood with no oxygen switches into veins, into the inferior vena cava, right atrium, tricuspid valve, right ventricle, pulmonary artery, lungs!
Inferior vena cava
Right atrium
The caudal vena cava returns blood to the heart. It return deoxygenated blood
Inferior vena cava and superior vena cava.
The superior vena cava.
Blood is returned to the heart via the vena cava, specifically the superior vena cava from the upper body and the inferior vena cava from the lower body.
the inferior vena cava caries de-oxygenated blood.
The vena cavae, which returns blood from the bottom half of your body back to your heart.
Your superior vena cava brings blood into the heart from the top section of your body, whereas the inferior vena cava brings the blood in from the bottom half of the body.
The superior vena cava brings deoxygenated blood into the heart, into the right atrium. The superior vena cava is formed by union of the right and left brachiocephalic (innominate) veins.
I beleive the answer to your question is vena cavai dont know much about the vena cava but pretty much any other site you go on it will tell you that the vena cava is the blood vessel that carrie blood from the body to the heart to the right atrium
The vena cava (both) are very large veins. All veins carry blood back to the heart. In the case of the vena cava, this is blood from the upper body (superior vena cava) and from the lower body (inferior vena cava).
