ANATOMY

Detailed explanation-1: -Hormone is a chemical substance secreted by an endocrine gland, which is directly poured into the blood stream and acts on a target organ or cells.

Detailed explanation-2: -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.

Detailed explanation-3: -Hormones act as chemical messengers that are released into the blood stream to act on an organ in another part of the body. Although hormones reach all parts of the body, only target cells with compatible receptors are equipped to respond.

Detailed explanation-4: -Hormones are your body’s chemical messengers. They travel in your bloodstream to tissues or organs. They work slowly, over time, and affect many different processes, including: Growth and development.

Detailed explanation-5: -Though few hormones circulate dissolved in the blood-stream, most are carried in the blood, bound to plasma proteins. For example, steroid hormones which are highly hydrophobic, are transported bound to plasma proteins.
