The endocrine system is a network of glands across the body that secrete chemical messengers called hormones. Below is an outline of different glands, the hormones they release and the action on the body. Gland Hormones Action The gland’ as it controls all other glands, for ‘Master Pituitary gland Oxytocin example, TSH signals action in the thyroid, ACTH signals Thyroid Stimulation action in the adrenal glands. Hormone (TSH) ACTH Primarily involved with the regulation of metabolism, Thyroid gland Thyroxine such as the conversion of food into energy for the muscles. PTH essentially acts to increase the concentration of Parathyroid gland Parathormone calcium in the blood from kidneys and bone. Promotes the absorption of from the blood into , and Pancreas Insulin cells. Responsible for reacting to threat via the fight or flight Adrenal glands Adrenaline & response. Noradrenaline Responsible for the development and regulation of Ovaries (female) Oestrogen and the female and . progesterone A key role in the development of system such as the Testes (male) Testosterone testes and , as well as promoting such as increased and mass, and the growth of .
