    The nephron is the functioning unit of kidneys. Nephron consists of a capsule shaped structure called Bowman’s capsule. The filtration of blood takes place in Bowman’s capsule under very high pressure. After that waste product goes to a network of collecting tubules which finally meet in a common collecting duct. The collecting duct meet in ureter which carries urine to the urinary bladder.

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.
