THE THYROID GLAND A large secretor do up of two lobes joined by a replacement mass (isthmus), located at the base of the throat. Composed of obtrude structures called follicles. The function of the thyroid secreter gland is to take iodine, gear up in many foods, and convert it into thyroid hormones: Thyroxine (T4) and tonne (T3). thyroidal carrels are the only cells in the organic structure that are adequate to(p) to absorb Iodine. These cells combine iodine and the aminic acid tyrosine to ramp up T3 and T4. THE HORMONES T3 and T4 controls the rate of glucose being burn or oxidized and converted to eubstance heat or chemic energy (bodys major(ip) metabolic hormone). Every cell in the body depends upon thyroid hormones for regulation of their metabolism. Thyroxine (T4) is the major hormone secreted by the thyroid follicles. Most Triiodothyronine (T3) is form at the buns tissue by the conversion from Thyroxine. (All cells neediness constant sum up of chemical energy so therefore all body cells are tar set abouts). CHEMICAL variance Each hormone is constructed from two conjugate tyrosine amino acids with limit Iodine atoms. T3 has 3 iodine atoms and T4 has four.
REGULATION-NEGATIVE FEEDBACK The thyroid gland is down the stairs control of pituitary gland. When the level of hormones(T3 and T4) drops also low, the pituitary produces thyroid gland stimulating hormone (TSH). TSH past stimulates the thyroid gland to produce more hormones. The thyro! id gland makes and secretes the hormones, which raises their level in the blood. The pituitary gland senses this and decreases the levels of TSH hormone. DISORDERS HYPERTHYROIDISM An overproduction of t3 and t4. some(prenominal) things can cause this such as gravid`s disease or a damaged thyroid gland. sculpt disease is when your immune system mistakenly attacks your thyroid...If you desire to get a full essay, order it on our website:
