- homeostasis
- maintains optimal conditions for enzyme action and all cell functions
- controls in the body
- blood glucose concentration
- monitored and controlled by the pancreas
- when too low; pancreas produces insulin, glucose moves from the blood into the cells
- in liver and muscle cells excess glucose is converted to glycogen for storage
- when too low; pancreas produces hormone glucagon which causes glycogen to be converted into glucose
- when too low; pancreas produces insulin, glucose moves from the blood into the cells
- diabetes
- type 1; pancreas fails to produce sufficient insulin leading to uncontrolled glucose levels
- normally treated by insulin injection
- type 2; obesity is a risk factor
- body cells no longer respond to insulin
- common treatments include changing diet and increasing exercise
- type 1; pancreas fails to produce sufficient insulin leading to uncontrolled glucose levels
- monitored and controlled by the pancreas
- body temperature
- thermoregulato-ry centre
- contains receptors sensitive to the temperature of the blood
- skin
- contains temperature recpetors
- sends nervous impulses to the thermoregulato-ry centre
- thermoregulato-ry centre
- water levels
- blood glucose concentration
- response to internal and external change
