both the superior and inferior vena cava pump the blood into the right atrium.
Then, the right atrium pumps the blood through a valve, and into the right ventricle.
inferior vena cava
coronary sinus
right atrium
Lowest carbon dioxide content would be the vessel right after the lungs, pulmonary vein to the left atrium.
The right atrium receives deoxygenated blood, then the blood moves into the right ventricle. So both of them receive deoxygenated blood. Once the blood returns from the lungs it is oxygenated and comes into the heart through the pulmonary veins into the left atrium then to the left ventricle then out to the body.
No. Right atrium is collecting venous (low oxygen) blood from all over the body.
There are two the superior (from the head) and inferior (from the body) vena cava.
oxygenated blood
The superior vena cava conducts blood from the head to the right atrium.
Blood that comes in to the right atrium comes from the pulmonary vein.
capilaries
th blood vessel that goes to the right atrium is cava
coronary sinus
The Superior and inferior vena cava.
The superior vena cava
blood first enters the heart through the right atrium.
vena cava (superior and inferior)
Deoxygenated blood returns to the heart from the rest of the body via the inferior vena cava which brings blood from the lower half of the body and the superior vena cava which brings blood from the upper half of the body. The inferior and superior vena cava join at the right atrium of the heart.
