The endocrine gland, a crucial part of the human body’s regulatory system, functions without ducts, unlike exocrine glands. It secretes hormones directly into the bloodstream, influencing the activity of target cells and organs throughout the body. These hormones serve as chemical messengers, controlling numerous physiological processes such as metabolism, growth and development, reproduction, and stress response. Endocrine glands include the pituitary gland, thyroid gland, adrenal glands, pancreas, ovaries, and testes, among others.
Each gland produces specific hormones that play vital roles in maintaining homeostasis and coordinating various bodily functions. Despite lacking ducts, endocrine glands possess a rich blood supply that allows hormones to be transported efficiently to target tissues across the body. The intricate interplay of hormones produced by the endocrine system ensures proper regulation of bodily functions and enables adaptation to internal and external environmental changes, contributing to overall health and well-being.
