Mammals and birds are warm blooded animals. This means they can control their body temperature and don’t have to depend on environment for their body temperature regulation. Because of this birds and mammals require optimum oxidization of glucose which would be possible with good supply of oxygen. BRead more
Mammals and birds are warm blooded animals. This means they can control their body temperature and don’t have to depend on environment for their body temperature regulation. Because of this birds and mammals require optimum oxidization of glucose which would be possible with good supply of oxygen. By developing four chambered heart they have made it possible to completely segregate the oxygenated and deoxygenated blood in their bodies which is their need because of their habit and habitat.
There are two types of respiration for oxidization of glucose. (a) Aerobic respiration: This involves complete oxidation of glucose hence optimum output of energy is achieved. This happens in presence of oxygen. (b) Anaerobic respiration: As the name suggests this happens in the absence of oxygen heRead more
There are two types of respiration for oxidization of glucose.
(a) Aerobic respiration: This involves complete oxidation of glucose hence optimum output of energy is achieved. This happens in presence of oxygen.
(b) Anaerobic respiration: As the name suggests this happens in the absence of oxygen hence complete oxidation of glucose does not take place. Usually bacteria show anaerobic respiration. Even sometimes in our calf muscles anaerobic respiration takes place.
Complex organisms have highly differentiated tissues and organs and not a single cell of a tissue is able to produce another type of tissue. For example, a dog is a complex multicellular organism and if we cut dog into two parts, then the cells of one part are not able to produce cells of other bodyRead more

For example, a dog is a complex multicellular organism and if we cut dog into two parts, then the cells of one part are not able to produce cells of other body part to produce a complete dog but in case of hydra (simple organism), regeneration takes place because cells in the cut body part are able to produce cells of other body parts.
Why is it necessary to separate oxygenated and deoxygenated blood in mammals and birds?

Can you think of reasons why more complex organisms cannot give rise to new individuals through regeneration?
