Exploring the System
The skin plays a major role in maintaining homeostasis:
Hairs on the skin trap warmth Glands under the skin secrete sweat onto the
surface of the skin in order to increase heat loss if the body is too hot
Capillaries near the surface can open when your body needs to cool off and close when you need to conserve heat
Interrelationships
The skin works with other body systems to keep the body functioning properly
Circulatory System – because of capillaries below the skin's surface, patches can be used to deliver medications through the skin into the blood for things such as heart problems
Interrelationships
The skin works with other body systems to keep the body functioning properly
Neurons embedded in the skin are used to send signals to the spinal cord and then to the brain
Ex. – touching a hot stove, or stumping your toe
