what I don't understand u
The right atrium of the heart receives oxygen-poor blood from the body.
I'm no anonomy expert, but the blood carried from the heart to the body is oxygen rich while the blood coming from the body has had it's oxygen absorbed so it goes through the heart to the lungs, where it gets oxygen, back to the heart and out to the body again.
Blood is pumped by the heart. Blood leaves the heart via the arteries and returns to the heart via the veins. Blood returning to the heart goes to the lungs where it is oxygenated then pumped around the arteries
In humans, the heart has four openings (or chambers). There is an opening for the oxygen-poor blood going in, one for the oxygen-poor blood going to the lungs, an opening for the oxygen-rich blood coming back from the lungs, and one for the oxygen-rich blood circulating through the rest of the body.
its called bleeding
actually, no. that work is reserved for atria since they are referred to as the collecting chambers of the heart. the ventricles are the pumping chambers. however, it is only the right atrium that collects oxygen poor blood. the left atrium collects oxygen rich blood coming from the lungs.
In the lungs, the carbon dioxide from oxygen-poor blood ("used" blood) is released from the body through exhalation and is replaced by oxygen through inhalation, turning the oxygen-poor blood into oxygen-rich blood.
Whit blood cells. :]
The right chambers have oxygen poor blood. The right atrium receives oxygen-poor blood from the body circulation, and the right ventricle pumps it to the lungs.
It is coming from the vena cava. This carries deoxygenated blood from the body.
