HOMEOSTATIS

HOMEOSTATIS

Homeostasis is defined as the maintenance of a constant internal environment within an organism.

Internal environment means the immediate surroundings of the cells. In mammalian tissues the cells are generally surrounded by tiny channels and spaces filled with fluid.

The most important features of the internal environment that must be kept constant are:

• Chemical constituents, for example, glucose ions, etc.

• Heart rate 

• Its osmotic pressure, determined by the relative amounts of water and solutes.

• The level of carbon dioxide

• Its temperature
