I think it is because if they weren't then our body would be pumping around semioxygenated blood and we all know we can't survive without oxygen
birds and mammals need comparatively more energy for maintaining their body temp this can can be maintained by separating oxygenated and de-oxygenated blood
it makes it easier for the lungs to get rid of carbon dioxide.and makes sure only blood with oxygen not carbon dioxide travels to the rest of thebody
mammals have double circulation which means that during one circulation blood passes twice through the heart. It is necessary because double circulation is important in humans because it keeps oxygenated and deoxygenated blood separate and moreover it circulate blood to organs efficiently.
If the poor meet the rich it might become use4less to your heart.
Yes: the left atrium (receives oxygenated blood from the pulmonary vein) and the right atrium (receives deoxygenated blood from the venae cavae).
Simple answer-The four chambered heart increases the efficiency of delivery of oxygenated blood to tissues by preventing mixing with deoxygenated blood
the purpose of having 4 chambers is they help pumb blood roung your body. they are very helpful because that means your heart doesnt have do it on its own that's why i know lots about the heart chambers xx
Marine mammals, like all other mammals, have a four-chambered heart with a complete divide. The right atrium receives deoxygenated blood from the veins and pumps it into the right ventricle. The right ventricle pumps it into the pulmonary artery, which delivers it to the lungs, where it is oxygenated. The blood then goes to the the left atrium, which pumps it into the left ventricle. The left ventricle pumps the blood into the aorta, which distributes the blood into smaller arteries all over the body.
Neither. It is a fish. That is why it is called a “Puffer fish.”
Aquatic mammals are mammals that can swim and live in water if necessary.
One side to take the deoxygenated blood from the body and send it to the lungs and the other side to receive the oxygenated blood from the pulmonary system and pump it out to the bocy for use.
No. They are birds. Birds and mammals are separate classes of animal.
