The endocrine system is one of the ways to communicate within the human body. It consists of a group of cells that secrete chemicals called hormones.

The human body contains many hormones that regulate the various functions of the body.

Hormones are known as body chemicals produced by the endocrine glands, which include pituitary glands, adrenal glands, thyroid glands, thymus, and pancreas.

Hormones are characterized by secretion at some particular place in the body, but they work far away from this place, but some hormones also affect nearby the place of secretion.
