Blood glucose level homeostasis uses the pancreas to secrete insulin and

glucagon to maintain level blood glucose levels.


✓ Give examples of homeostatic process




It contains a receptor, afferent pathway, a control center, an efferent

pathway, and finally an effector.


✓ What are the components of a feedback loop?




A negative feedback system has the body act to reverse the direction of

change. This tends to keep things constant. Because of this, it is the most

norepinephrine, increased thyroxine for elevating metabolism, and

increasing physical activity.


✓ How does the body regain homeostasis during hypothermia?




65%


✓ What percentage of human body is water.
