The Thyroid Hormones (T4 And T3)

THE THYROID GLAND A large secretor do up of two lobes joined by a metamorphose mass (isthmus), located at the base of the throat. Composed of fag social organizations called follicles. The function of the thyroid gland gland is to take iodine, entrap in many foods, and convert it into thyroid hormones: Thyroxine (T4) and thyroxine (T3).  thyroidal cadres are the only cells in the organic structure that are adequate to(p) to absorb Iodine. These cells combine iodine and the amino group acid tyrosine to ramp up T3 and T4. THE HORMONES T3 and T4 controls the rate of glucose being burned or oxidized and converted to eubstance heat or chemical 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 (T 3) is form at the buns tissue by the conversion from Thyroxine. (All cells collect constant sum up of chemical energy so therefore all body cells are tar pretends). CHEMICAL affiliate Each hormone is constructed from two conjugate tyrosine amino acids with terminal point Iodine atoms. T3 has 3 iodine atoms and T4 has four.

REGULATION-NEGATIVE FEEDBACK The thyroid gland is beneath control of pituitary gland. When the level of hormones(T3 and T4) drops also low, the pituitary produces thyroidal stimulating hormone (TSH). TSH past stimulates the thyroid gland to produce more hormones. T! he thyroid 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.  galore(postnominal) things can cause this such as gravid`s disease or a damaged thyroid gland. sculpture disease is when your immune system mistakenly attacks your thyroid...If you desire to get a full essay, order it on our website: OrderCustomPaper.com
