There are two types of hormones secreted in the endocrine system: Steroidal (or lipid based) and non-steroidal, (or protein based) hormones. The endocrine system provides an electrochemical connection from the hypothalamus of the brain to all the organs that control the body metabolism, growth and development, and reproduction. Without hormones, you could not grow, maintain a constant temperature, produce offspring, or perform the basic actions and functions that are essential for life. The ability to maintain homeostasis and respond to stimuli is largely due to hormones secreted within the body.
Yet this occurs in our bodies every day of our lives. It seems like a far fetched idea that a small chemical can enter the bloodstream and cause an action at a distant location in the body. Hormones act as "messengers," and are carried by the bloodstream to different cells in the body, which interpret these messages and act on them. The endocrine system is a control system of ductless glands that secrete hormones within specific organs. 5.1.1 T3 and T4 Function within the body.Increases heart rate, oxygen intake, and blood flowĬontrols sexual growth and function. Affects growth, maturation, and nervous system activity. Plays the most important role in controlling blood calcium levelsĬontrols metabolism. Grows the lining of the uterus for fertilization. Triggers the metabolism of glucose, protein, and fat.Īffects growth and function of uterus and breasts. Triggers the making and release of thyroid hormonesĪffects the making of red blood cells (RBCs) Starts and keeps up the making of milk in breasts. May play a role in trust and bonding, especially between parents and children. Triggers contraction of the uterus and milk release in breasts during breastfeeding.
Luteinizing hormone (LH) and follicle-stimulating hormone (FSH)Ĭontrols the making of sex hormones (estrogen and testosterone) and the making of eggs and sperm. Controls blood pressure.Ĭontrols the making of cortisol and other steroids in the adrenal glands.Īffects growth and development. Controls salt and water balance.Īffects water retention in kidneys and sodium balance. Controls blood sugar levels, blood pressure, and muscle strength. Response to injury, stress, and environmental factorsīelow is a list of hormones what they do in your body:Ĭontrols salt, water balance, and blood pressureĬontrols key functions in the body.
These are chemicals that control and coordinate many things in your body.
