Body maintain Homeostasis by Negative Feedback mechanism. Because the stimuli causing the disturbance in the Homeostasis of the body is to be counteracted by a mechanism.

<h3></h3><h3>What is homeostasis?</h3>

The Homeostasis of the body is defined as the regulation of the internal environment of the body when there is a change.

In Positive feedback mechanism, it increases the response of the stimuli In temperature regulation, the stimuli are hot and cold.

Both are controlled by a opposing negative feedback mechansim that is when the body temeprature increases it is decreased to normal by a negative feedback mechanism , likely when the body temeprature is decreased(cold) , the body will increase the Body temeprature to normal By a Negative feedback mechanism that is exactly opposite(opposing) to the Former Negative feedback mechanism pathway.

In termparature regulation when body temperature raises ----->detected by nerve endings in the skin--Hypothalamus -----> signal to blood vessel for dilation activation of the sweat gland-the tempertaure is maintained to normal. -> signal send to the>heat is lossed and when body temperature decreases -----> detected by nerve endings in the skin------> signal send to the hypothalamus -----> signal to blood vessel for constriction inhibition of secretion from sweat gland, shivering ---->heat is generated -->normal.
