MYP Integrated Sciences Hormones Key Definitions

Definition

Endocrine gland

A gland that makes and releases hormones directly into the bloodstream.

Definition

Hormone

A chemical messenger released by glands that travels in the bloodstream to target organs, where it produces a specific response.

Definition

Receptor

A molecule on a target cell that detects and responds to a specific hormone.
