Homeostasis GapFill

 HomeostasisHomologyThermoregulationMyopia is the control of the internal environment of either the body or a cell, so that optimum conditions are controlled, despite any external or internal changes. Examples of systems controlled by this mechanism include the amount of water in the body, the temperature of the body, and the blood  glucosecellstarchATP concentration. Either nervous or  hormonalcontrolgeneticmuscular systems are used to control these levels, and all include a  detectorglandreceptorhormone, a coordination centre and an effector.

The human body must work within a very narrow temperature range, as beyond these temperature ranges,  cellscell membranesmusclesenzymes are not able to function. Body temperature is detected by the  hypothalamuspituitary glandadrenal glandsthyroid gland. If too high, blood vessels  shortendilateconstrictare removed and the sweat glands become activated.

The pancreas is the endocrine tissue that is responsible for  producing calciumproducing glucoseblood calcium concentrationblood glucose concentration. When the concentration is high, the pancreas is stimulated to produce  testosteroneinsulinoestrogenglucagon. This causes the movement of  glucoseglycogenureaoxygen from the blood into liver and muscle cells, and excess is converted into  glucagonstarchglycogencellulose.

Failure to control blood glucose concentration is an indicator of diabetes.  AcuteChronicType 1Type 2 diabetes is when the pancreas fails to produce enough insulin, as opposed to the body no longer being able to respond to the insulin produced.
