Endocrine Gland Functions
Endocrine glands are specialized organs that secrete hormones directly into the bloodstream, regulating vital body processes. These hormones control growth, metabolism, reproduction, mood, and homeostasis. Major endocrine glands include the pituitary, thyroid, adrenal, pancreas, and gonads. Each gland produces specific hormones that communicate with target organs, ensuring the body responds appropriately to internal and external changes, maintaining overall balance and health.

💡 Key Takeaways
- Identify the major endocrine glands and the key hormones they produce.
- Explain how hormones regulate metabolism, growth, reproduction, and stress responses.
- Describe the mechanisms by which hormones act on target cells, including receptors and feedback loops.
- Differentiate endocrine signaling from nervous system signaling and understand how hormones maintain homeostasis.
❓ Frequently Asked Questions
What is the primary function of endocrine glands?
To release hormones into the bloodstream that regulate metabolism, growth, development, and maintaining homeostasis.
How do hormones reach their target organs?
Hormones travel through the bloodstream and bind to specific receptors on target cells, eliciting a response.
What is negative feedback in the endocrine system?
A regulatory loop where rising hormone levels reduce further secretion to maintain stable internal conditions.
Why is the pituitary gland often called the master gland?
Because it secretes hormones that control other endocrine glands and responds to hypothalamic signals.
