Frequently Asked Questions
What is the Endocrine System
The human endocrine system is composed of various ductless glands that secrete various important hormones in the body. These hormones perform many functions starting from mood regulation, development and growth, metabolism, mechanism of action of organs, and so on. The primary function of the endocrine system is to check how hormones are released, depending upon the level of hormones produced and other substances present in the blood.
Endocrine Glands in the Human Body
Hypothalamus: Main functions of the hypothalamus include regulating body temperature, thirst, hunger, sleep, emotions, moods and even regulating the release of various hormones from the endocrine glands.
Thymus Gland: The thymus secretes the hormone thymosin which stimulates the production of T cells in the body which plays an important role in immunity.
Pineal Gland: This small gland is believed to be involved in the production of the sleep-regulating hormone melatonin.
Pituitary Gland: The pituitary gland influences the growth and development of an individual.
Parathyroid Gland: This gland secretes hormones that help regulate calcium levels in the body.
Thyroid Gland: The thyroid gland is responsible for secreting thyroid hormones and calcitonin that regulate metabolism and calcium absorption,
Adrenal Gland: The hormones secreted by the Adrenal gland regulate cortisol and stress hormones, a hormone responsible for raising blood glucose levels.
Pancreas: Pancreas produces insulin in the body, a hormone that maintains blood sugar levels.
Testes and Ovaries: Testes are responsible for the production of sperm. Just like testes, ovaries are the glands that produce female sex hormones.
