helps regulate and maintain various body functions by synthesizing (making) and releasing hormones‚ chemical messengers. The major areas of control and integration include responses to stress and injury‚ growth and development‚ absorption of nutrients‚ energy metabolism‚ water and electrolyte balance‚ reproduction‚ birth‚ and lactation. The endocrine system is composed of glands that release their hormones directly into the bloodstream for chemical signaling of target cells. These glands include

Overview of the Endocrine System * System of ductless glands that secrete hormones * Hormones are “messenger molecules” * Circulate in the blood * Act on distant target cells * Target cells respond to the hormones for which they have receptors * The effects are dependent on the programmed response of the target cells * Hormones are just molecular triggers * Basic categories of hormones * Amino acid based: modified amino acids (or amines)‚ peptides (short chains
