Answer 1

$\underline {\Huge \text{Question 1:}}$

How do feedback mechanisms regulate the hormone system?

$\underline{\Huge\text{Answer :-}}$

The timing and amount of hormone released is regulated by feedback mechanism. For example, if the sugar levels in the blood increases, they are detected by the cells of pancreas which respond by producing more insulin. On the other hand, as the blood sugar level fails insulin secretion is reduced. Not only pancreas, feedback mechanism is present in every gland.

$\underline {\Huge \text{Question 2:-}}$

Why pituitary gland is called as master gland? Where it is located? Write its two functions?

$\underline {\Huge \text {Answer :-}}$

Pituitary gland is called the master of glands because it regulates and controls all other glands of the body.

Pituitary gland is attached with the hypothalamus of the brain by a stalk like structure called INFUNDIBULUM.

☯ Growth hormone which regulates the growth of muscles and bones.

☯ Vesopresin which maintains ionic balance and water levels in our body.

☯ Prolactine which regulates the secretion of mammary glands.
