Question

Explain how the separation of oxygenated and deoxygenated blood helpful in humans

Answer 1

1.High energy requirements of warm blooded animals (ie, humans)To maintain constant body temperature Allows more efficient supply of O2 to human cells. 2.

Double circulation describes the fact that our oxygenated and deoxygenated blood is kept separate in our hearts. In fish (two-chambered heart) and amphibians (three-chambered heart), the oxygenated and deoxygenated blood is allowed to mix in the ventricles, in mammals and birds (four-chambered heart), the oxygenated and deoxygenated blood is kept separate. Fish and amphibians are cold-blooded, meaning that they conform to the temperature of their environment. Mammals and birds are warm blooded. They maintain a constant internal temperature, despite the environment. Maintaining a constant internal temperature allows mammals and birds to carry-out body processes more efficiently, but it requires more energy. Without double circulation, the body tissues would not receive enough oxygen to maintain a constant temperature, and would die.

Answer 2

Answer...

Human have humans have four chambered heart which consists of two or three and two ventricles in the four chambered heart the left side and right side of an heart are completely separated to prevent the oxygenated blood from mixing with deoxygenated blood such a variational of high efficient supply of oxygen to the body cells which is necessary for producing a lot of energy this energy is useful for warm blooded animals which have high energy needs to maintain their body temperature
