Study Notes
Overview of the Endocrine System
- The body uses a system of control mechanisms to maintain stability, known as homeostasis.
- The endocrine system plays a key role in this process.
- Endocrine control is achieved through biochemical regulators, including:
- Hormones: Chemical messengers produced by glands and transported through the bloodstream to target cells.
- Paracrine factors: Local regulators that act on neighboring cells (e.g., prostaglandins).
- Autocrine factors: Local regulators that act on the same cell that produced them (e.g., interleukins).
