Why Is It Important to Maintain Homeostasis in Living Organism?
Now that you have learned about what is homeostasis and its types, let’s move ahead to know its importance in a living organism.
How does homeostasis work?
The receptors work when the body goes to a different temperature from the regular. It works in both external and internal environments. The control center works on the respiratory center and renin-angiotensin system. And at last, an effector works to bring the body temperature back to normal. So, it can be identified that homeostasis is important for the body and works for every part of it.
What is the process of maintaining the core temperature of the body?
Thermoregulation - It is the process of maintaining the core temperature of the body. It helps to control the temperature according to the environment, either it is high or low from normal temperature. But it remains only for some time; the thermoregulation brings it back to the normal temperature. It is maintained by the organs like adipose tissue and skin. It works in the integumentary system and hypothalamus brain.
What is homeostasis in biology?
It refers to the tendency to maintain the internal states and psychological conditions in the living organism. In other terms, it’s a self-regulatory process through which it adjusts the body according to the temperature needed for survival. All that works in the balance to maintain the homeostasis in the body. This term was originated by one of the great American psychologists, Walter Bradford Cannon, in1962. He created homeostasis to know the equilibrium that is needed for the body to survive in different temperatures.
What is the process of osmoregulation?
Osmoregulation - It is the process by which osmotic pressure is handled inside the body by creating the balance between fluid and salt.
