As part of maintaining homeostasis, why are hormones, secreted by endocrine cells, continuously inactivated?
IceJOKER [234]

Answer:

Homeostasis refer to as the maintainence of equillibrium within the body. Endocrine systems play a major role in maintainence of equillibrium. The hormones released are continuously inactivated by negative feeback system to maintain homeostsis.

Explanation:

Homeostasis in a body is refered as a dynamic equillibrium which constantly changes. Feedback regulation systems maintain homeosatsis.

The release of hormones into the blood is controlled by a stimulus. A stimulus can increase or decrease the release of hormones.The response to a stimulus changes the internal conditions and may itself become a new stimulus. This self-adjusting mechanism is called feedback regulation.

There are two types of feedback systems.

Negative feedback occurs when the response to a stimulus reduces the original stimulus. Positive feedback occurs when the response to a stimulus increases the original stimulus.

If the hormones released are not controlled by these feedback systems, enormous amount of hormones will change the whole internal enviornment of the body ,hence, equillibrium will be disturbed and result in death of cells and death of an indivisual.
