The Endocrine System regulates the body's metabolism, growth, and functions of the sexual organs. It consists of glands that secrete hormones directly to the circulatory system that are carried throughout distant target organs. This system is responsible for controlling the chemical functions of cells, tissues, and organs through the secretion of different types of hormones.
The Endocrine Systems includes the different glands (e.g. adrenal, parathyroid, thyroid, and pituitary), ovaries, pancreas, and testes.
