The endocrine system is a control system of ductless glands that secrete hormones within specific organs. Hormones act as "messengers," and are carried by the bloodstream to different cells in the body, which interpret these messages and act on them.

first in an eight-part series on the anatomy and physiology of the endocrine system – explores the nature of endocrine glands and tissues, and the role of hormones as chemical signals that are carried in the blood.
26 wrz 2022 · Understanding the physiology of hormones and how they result in pathological conditions is important. Hormones of the endocrine system are a vast topic with numerous hormones involved, affecting virtually every organ in the human body.
A hormone is a chemical substance released by a cell or a gland in one part of the body that sends out messages that affect cells in other parts of the organism. Only a little amount of hormone is required to alter cell metabolism, it is a chemical messenger that transports a signal from one cell to another.
