What is an endocrine gland?

An endocrine gland is a type of gland that secretes hormones directly into the bloodstream rather than through a duct. These hormones are then transported via the blood to various organs and tissues throughout the body, regulating multiple bodily functions and processes. The endocrine system, which includes these glands, plays a crucial role in maintaining homeostasis by controlling functions such as metabolism, growth, and mood. Examples of endocrine glands include the pituitary gland, which is often referred to as the "master gland" because it controls other glands in the endocrine system, the pancreas, which secretes insulin and glucagon to regulate blood sugar levels, and the adrenal glands, which produce hormones like adrenaline and cortisol.
