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 concentration. Either nervous or systems are used to control these levels, and all include a , a coordination centre and an effector.
The human body must work within a very narrow temperature range, as beyond these temperature ranges, are not able to function. Body temperature is detected by the , and if too high, the sweat glands become activated.
The pancreas is the endocrine tissue that is responsible for . When the concentration is high, the pancreas is stimulated to produce . This causes the movement of from the blood into liver and muscle cells, and excess is converted into .
Failure to control blood glucose concentration is an indicator of diabetes. 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.
