endocrine glands
Endocrine glands are specialized organs that produce and release hormones—chemical messengers that travel through the bloodstream to regulate various bodily functions such as growth, metabolism, mood, and reproduction. Unlike exocrine glands (which release substances outside the body), endocrine glands release hormones directly into the blood. Examples include the pituitary gland, thyroid, adrenal glands, and pancreas. These glands work together to maintain internal balance, or homeostasis, ensuring the body's systems operate smoothly and effectively.
