Endocrine System Essay

The endocrine system is one of the major systems in the body, it is one of the two systems established for regulating the body to achieve homeostasis. This system plays a role in long distance intercellular communication, coordination, and homeostasis control (Rice University-Open Stax, 2016). It is made up of a collection of glands which produce hormones, regulate metabolism, growth and development, tissue function, sexual function, reproduction, sleep, mood, in addition to a plethora of other things (Zimmermann, 2016). The glands included in this system are the pituitary gland, thyroid gland, parathyroid glands, adrenal glands, pancreas, ovaries in females, and testicles in males (Zimmermann, 2016). These glands are ductless and release their products into the blood or lymph. These products are hormones which come in three classes: steroid glands that secrete these hormones in the testes, ovaries, and adrenal cortex, proteins, and catecholamine.
With the endocrine system being made up of multiple glands there are also …show more content…
Studies have shown that where levels of thyroid hormones are low, usually HGH levels are low as well (Reed, N.A). Furthermore, HGH can inhibit the cellular utilization of glucose as an energy source, when used by endurance athletes it increases fat metabolism instead of CHO. HGH stimulates the catabolism of fats and the conversion of glycogen to glucose. Combined with the stimulation of Thyroxine (TSH) and HGH increase catabolism thereby the result is an additional supply of energy to the body. There are some other impacts of HGH which are negative. One of which is the hypersecretion of HGH. This produces gigantism, in adults’ bones of the hands, feet, cheek, and jaws thicken; tissue growth such as thickening of the eye lids, as well as the skin itself thickening especially on the feet and
