endocrine physiology

Endocrine physiology involves glands that release hormones—chemical messengers—into the bloodstream to regulate various body functions. These hormones control processes like growth, metabolism, mood, and reproduction by signaling target organs or tissues. Unlike nerves that send rapid signals, hormones work more slowly but have lasting effects. The endocrine system includes glands such as the thyroid, adrenal, and pancreas. It maintains overall balance and responds to changes in the body and environment, ensuring proper functioning and health.
