blood is pumped through lungs
To remove CO2 and to replenish the O2 in the blood.
The lungs pull in oxygen which is then taken into the blood stream which is pumped round the body by the heart.
Unlike mammals, fish absorb oxygen directly into the blood stream at the gills. They don't have lungs so blood doesn't have to be pumped to the lungs to be oxygenated before it can be pumped round the body so they only need 2 chambers in their heart
You breath in oxygen, oxygen goes to the lungs. The oxygen is carried from the lungs to the heart. The blood cells are filled with oxygen, then pumped through your body. If you feel on your neck below your jaw, you should feel your pulse. This is an artery pumping blood to your brain. Then, the used blood is pumped back to your heart to receive more oxygen and then is pumped back to somewhere in your body.
On the right side of the heart there is deoxygenated blood which has already been pumped round the body and is now returning to the heart. On the left side of the heart there is oxygenated blood which has just come from the lungs and is about to be pumped round the body Hope this is useful can't quite renember the names and technical words.. sorry...
The red blood cells carry the oxygen from the lungs round the body. The heart pumps the red blood cells to go around the body. When the oxygen is given to the cells, the red blood cells return to the heart and get pumped back to the lungs while carrying carbon dioxide.
The blood is pumped by the heart round the body in a circular system, so there is no actual end.
Plasma makes up 60% of blood and is pumped round the body by the heart.
Veins running back to your heart from your ear! Jk, the Veins flow thru your neck and the blood is reoxygenated to continue its cycle.
to get the heart and lungs pumpingg and get the blood round the body
You use your lungs to breath. Your heart pumps the blood round your body (including into and out of the lungs where gas exchange occurs when you breath).
as you breath in the oxygen it goes into your lungs and in thought the blood system around your body and once it is back in the lungs it is the carbon dioxide because the body has used all the oxygen and the you breath out the carbon dioxide.i hope this helps you if not i am sorry :(
