Enzymes are organic catalysts which aid in facilitating chemical reactions in the body. When functioned properly homeostasis is maintained.

The transitional epithelium is a unique kind of epithelium exclusive to the genitourinary tract. This epithelium is actually a stratified epithelium with the ability to contract or relax as needed (but this epithelium has no contractile element). This epithelium can transition from a stratified epithelium to a simple epithelium depending on the distension of the bladder hence the name transitional. This is perfect for the bladder because this functions to accommodate the urine storage function of the bladder by increasing its compliance.

The homeostasis of the human body works like a machine set at a particular standard. If the factors deviate from the standard values, the homeostatic mechanism come into action.
For example, if a cell requires certain protein, the respective genes get a signal and get activated. The cell start synthesizing the protein and when sufficient amount is made, there is a feedback loop, which allows the same protein to stop the synthesis as well. A lot of organs and cellular systems are involved in regulating the synthesis of this protein.
This is similar to the cooling system. If we set the temperature of the cooling system to certain degree, it will start cooling the room till the required temperature is reached. As soon as the temperature is acquired, the system cut-off automatically and the required temperature is maintained.
