Detailed explanation-1: -Along with the nervous system, the endocrine system coordinates the body’s functions to maintain homeostasis during rest and exercise. The nervous and endocrine systems also work together to initiate and control movement, and all the physiological processes movement involves.

Detailed explanation-2: -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-3: -What is a negative feedback mechanism? A negative feedback loop is one way that the endocrine system tries to keep homeostasis (stability) in the body. If an endocrine gland senses that there is too much of one hormone in the body, it will initiate changes to decrease production of that hormone.

Detailed explanation-4: -These are the nervous system and the endocrine (hormone) system. These systems regulate body processes through chemical and electrical signals that pass between cells.

Detailed explanation-5: -The major endocrine systems are regulated by negative feedback, a process believed to maintain hormonal levels within a relatively narrow range. Positive feedback is often thought to have a destabilizing effect.
