Homeostasis
What is the set point?
The regulation of temperature.
What is thermoregulation?
When the kidneys excrete substances that are not needed.
What is secretion?
Blood-clotting is an example of _________.
What is positive feedback?
The common type of feedback.
What is negative feedback?
Something that disrupts homeostasis.
What is stimulus?
The maintenance of a relatively constant internal despite varying environmental factors.
What is homeostasis?
Organisms that generate heat internally.
What are endotherms?
This organ helps regulate glucose levels.
What is the pancreas?
The regulation of water/solute concentration.
What is osmoregulation?
These detect changes from stimulus.
What are sensors/receptors?
When capillaries expand and fill with blood to release heat.
What is vasodilation?
Organisms that maintain constant internal conditions.
What are regulators?
A process in the kidneys where filtrate is processed or modified.
What is reabsorption?
The hormone released when blood-glucose levels are too low.
What is glucagon?
Any organ or cell that ultimately responds to stimulus.
What is an effector?
When muscles tighten and loosen to produce energy and therefore heat.
