Explanation: 

Detailed explanation-1: -The endocrine hormones help control mood, growth and development, the way our organs work, metabolism, and reproduction. The endocrine system regulates how much of each hormone is released. This can depend on levels of hormones already in the blood, or on levels of other substances in the blood, like calcium.

Detailed explanation-2: -The endocrine system maintains homeostasis through a series of feedback loops, the most important of which are controlled by the hypothalamus interacting with the pituitary gland . Often, the hypothalamus stimulates the pituitary gland to secrete an activating hormone to another gland.

Detailed explanation-3: -The endocrine system consists of ductless glands that secrete hormones into the blood stream. These hormones drive the homeostatic feedback loops that keep the body healthy and in equilibrium. The endocrine system is intimately integrated into physiological processes in order for it to carry out its functions.
