Endocrine System Endocrine glands-secrete chemical substances called hormones directly into the bloodstream for transport to target tissues. Hormones: three basic types 1. steroid hormones: are lipid originally synthesized from cholesterol There are more than 20 steroid hormones in the body, ie.  Hormones | Back to Top. The endocrine system is a collection of glands that secrete chemical messages we call hormones. These signals are passed through the blood to arrive at a target organ, which has cells possessing the appropriate receptor. The pancreas contains exocrine cells that secrete digestive enzymes into the small intestine and clusters of endocrine cells (the pancreatic islets). The islets secrete the hormones insulin and glucagon, which regulate blood glucose levels. Hormones are chemical substances that help to regulate processes in the body. Hormones are secreted by glands and travel to their target organs in the bloodstream. Several hormones are involved in the female menstrual cycle. Hormones are chemicals secreted by glands in the body. Different hormones affect different target organs. The bloodstream transports hormones from the glands to the target organs. Move the mouse over the different glands to see what they do. The pituitary gland secretes nine hormones that regulate homeostasis by stimulating other endocrine glands to produce and secrete their own hormones. The pituitary gland has two components: the anterior (front) pituitary (or adenohypophysis) and the posterior (back) pituitary (neurohypophysis). The endocrine system is one of two systems that control and coordinate many functions to keep our bodies working in balance, called homeostasis. Our nervous system uses electrical impulses, the endocrine system uses chemicals called hormones. Endocrine glands are glands of the endocrine system that secrete their products, hormones, directly into the blood rather than through a duct. The major glands of the endocrine system include the pineal gland, pituitary gland, pancreas, ovaries, testes, thyroid gland, parathyroid gland, hypothalamus and adrenal glands. The hypothalamus and pituitary gland are neuroendocrine organs. Local chemical messengers, not generally considered part of the endocrine system, include autocrines, which act on the cells that secrete them, and paracrines, which act on a different cell type nearby. Hormones: Chemical substances secreted by endocrine glands that are carried in the bloodstream to tissues and organs, stimulating them to maintain and regulate basic bodily functions. Metabolism: Sum of all the physiological processes by which an organism maintains life. The pituitary gland has long been called the master gland because it regulates many other endocrine glands. It secretes multiple hormones that, in turn, trigger the release of other hormones from other endocrine sites. The endocrine system is the human body's network of glands that produce more than 100 hormones to maintain and regulate basic bodily functions. Hormones are chemical substances carried in the bloodstream to tissues and organs, stimulating them to perform some action. The pituitary gland has long been called the master gland because it regulates many other endocrine glands. It secretes multiple hormones that, in turn, trigger the release of other hormones from other endocrine sites. The adrenal gland is another endocrine gland regulated by the pituitary. The adrenal cortex, the outer part of each of the two adrenal glands, produces aldosterone, cortisol, and other steroids. These substances regulate salt concentration in body fluids and glucose, fat, and protein metabolism. Pituitary Control. The master gland, i.e., the gland that regulates many of the other endocrine glands, is the pituitary, located at the base of the brain. Also called the hypophysis, the pituitary secretes at least five hormones that directly affect the other endocrine glands. The endocrine system is a control system of ductless glands that secrete hormones within specific organs. Hormones act as messengers, and are carried by the bloodstream to different cells in the body, which interpret these messages and act on them. A hormone is a chemical messenger produced by a cell that effects specific change in the cellular activity of other cells (target cells). Unlike exocrine glands (which produce substances such as saliva, milk, stomach acid and digestive enzymes), endocrine glands do not secrete substances into ducts (tubes).
