Director of system Located at base of brain – right above mouth Many important types of hormones are produced in pituitary gland including growth, sexual development, and water hormones.
Attached to pituitary gland Connects nervous and endocrine system
Found deep in brain Sensitive to different levels of light Lets you know what is hot, cold, and when you need to sleep or wake up
Found by Adam’s apple in throat Releases hormones necessary for growth and metabolism Releases hormone that is responsible for regulation of calcium in body
Found in chest Helps body fight disease by producing white blood cells called T cells
Located on top of kidneys Produces hormones that balance carbohydrates, protein, fat, water, and salt levels Also produces hormones that make your heart beat faster when you hear loud noises, are on a roller coaster, or if you are stressed out
Part of digestive and endocrine systems Produces hormones to balance glucose in blood Located beneath stomach – connected to small intestine
Produce hormones that control sexual development Located in groin area
Kidneys make The heart produces hormone to balance hormones that production of red balance blood blood cells pressure Produced when These hormones tell oxygen level in the kidneys to blood decreases remove more salt
Feedback mechanisms in the body are called negative mechanisms, because the final effect of the response is to turn off the response. When the hormone has been made to much the final response is shutting down reproduction of that hormone. When the body needs energy the thyroid gland releases thyroxine to increase cellular respiration and the more cellular respiration the more body energy is released.
The outcome of the positive feedback is not to maintain homeostasis, but makes a response that increases. For example when you cut yourself you’re bleeding is controlled by positive feedback. First the damaged area sends a signal which starts a chain of chemical reactions that leads to good blood clot, that let the scab and white blood cells heal the open skin
The amount of one hormone depends on the balance or imbalance of another For example, the pancreas produces two different hormones - one (insulin) decreases level of sugar in blood - another (gulucan) decreases level of sugar in blood The balance of these hormones maintain a stable blood sugar
Too little or too less of any hormone can cause disease For example, if the pancreas produces too little insulin, sugar levels in blood rise to dangerous levels The high blood sugar levels can damage circulatory system and kidneys
