    Endocrine System Definition

    • The endocrine system is a collection of glands that produce hormones to regulate various bodily functions, including metabolism, growth, and mood.

    Difference Between Endocrine and Exocrine Glands

    • Endocrine glands secrete hormones directly into the bloodstream, whereas exocrine glands release substances through ducts to specific body surfaces.

    Similarities Between Endocrine and Nervous Systems

    • Both the endocrine and nervous systems coordinate and regulate physiological processes in the body, ensuring homeostasis and response to stimuli.

    Steroid Hormone Example

    • Examples of hormones from the steroid class include testosterone and estrogen, which are derived from cholesterol.

    Hormone Transport Mechanism

    • Hormones are transported through the bloodstream, allowing them to reach distant target organs and tissues where they exert their effects.
