The heart is really two pumps in one. It receives blood into its right side. This blood has been all around the body giving up its oxygen to all the various cells and collecting carbon dioxide. [This is the by-product of the cells using oxygen]. The heart then pumps this blood to the lungs where it exchanges the carbon dioxide that it has collected and takes on more oxygen. The blood is the returned to the heart but this time to the leftside. It is then pumped all around the body again. This freshly oxygenated blood contains 21% oxygen. When it returns to the right side of the heart having been all around the body, it still contains 17% of its oxygen which is why we are able to give mouth to mouth and successfully revive a person that has stopped breathing. Hope this helps.
The body needs oxygen, so the blood must go through the lungs to get the oxygen so when it circulates through the body, so the oxygen can get to all places.
The lungs give oxygen to the blood and take carbon dioxide away from the blood. Oxygen in and CO2 out.
One of the main purposes of blood is to transport oxygen from the lungs to the rest of the body. Of course to do this it must actually circulate through the lungs to collect the oxygen.
Because - the blood absorbs oxygen from the lungs, and the heart pumps the blood round the body !
It really doesn't pump it there first. The two 'circles' work together. While one goes to the body, the other goes to the lungs and they do act together.
The heart pumps blood to the lungs first it is because the lungs purify blood and send it to the other parts of the body
The left side of the heart pumps blood to the head and body. The right side of the heart pumps blood to the lungs
The heart pumps de-oxygenated blood to the lungs by pulmonary artery
The right side of the heart pumps blood to the lungs
The right heart pumps unoxygenated blood to the lungs, and the left heart pumps blood that contains oxygen from the lungs to the rest of the body.
The right side of the heart pumps blood to the lungs to pick up oxygen. From the lungs it goes back to the left side of the heart, which pumps it out to the rest of the body. Blood then returns to the right side of the heart and starts the cycle over.
The left side of the heart pumps blood to the head and body. The right side of the heart pumps blood to the lungs
The heart pumps de-oxygenated blood to the lungs by pulmonary artery
The right side of the heart pumps blood to the lungs
yes because the heart pumps blood to the lungs for you to breath
The right heart pumps unoxygenated blood to the lungs, and the left heart pumps blood that contains oxygen from the lungs to the rest of the body.
The right chamber pumps blood to the lungs to get oxygen.
It pumps deoxygenated blood to the lungs.
lungs pumps air to the heart and heart pumps air around body through blood
the right ventricle
The right ventricle of the heart.
Right ventricle
The right side of the heart pumps deoxygenated blood. The right atrium collects venous blood return from the superior and inferior venae cavae and the right ventricle pumps this blood to the lungs.
