What Is Endocrinology?
The endocrine system is a system consisting of endocrine glands. These glands are organs that synthesize and secrete hormones. Hormones control different activities in our bodies. Different types of hormones control reproduction, metabolism, growth, and development. Hormones also control our response to our environment and help provide the appropriate amount of energy and nutrients required for our body's functions. The glands that make up the endocrine system are the hypothalamus, pituitary, thyroid, parathyroid, pancreas, ovaries in women, testicles in men, adrenal glands, adipose tissue, endothelium (cells that line the inner wall of the vessels). Endocrinology is a branch of science that studies and treats diseases related to this system.
