
What is the Endocrine System?
 A method of communication between cells in the
body wherein glands produce hormones, which
affect distant target organs.
What is an endocrine gland?
 A gland that produces hormones
 A gland that releases hormones into the blood
What is a hormone?
 A chemical message in the blood
What is a target organ?

Endocrine System

What are the different types of hormones?





contact with all tissues, why don’t they affect all
tissues?

They require a receptor either on the cell surface
(polypeptide) or inside the cell (steroid)
