    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).
