MICROANATOMY

Detailed explanation-1: -Hormones act as chemical messengers that are released into the blood stream to act on an organ in another part of the body.

Detailed explanation-2: -The glands that make up the endocrine system produce chemical messengers called hormones that travel through the blood to other parts of the body.

Detailed explanation-3: -Endocrine glands release hormones into the bloodstream. This lets the hormones travel to cells in other parts of the body. 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.

Detailed explanation-4: -The cells in these glands secrete specific chemicals called hormones. Hormones circulate around the body via the blood stream and modulate cellular or organ functions by binding with receptors in the target cells. Hormones that stimulate and control the activity of other endocrine glands are called trophic hormones.
