homeostasis

• Sweating to cool the body down is an example of a negative-feedback mechanism.
• Increased stretching of the uterus caused by the contraction of the uterine muscles to push out the baby is an example of a positive-feedback mechanism.
• Homeostasis is the body’s maintenance of its internal conditions at a steady equilibrium with constant regulation as a response to changing conditions.
• Homeostasis of the body enables the body to respond to changes in temperature to maintain an internal temperature of 98.6°F.
• A body temperature that varies too much from this set point can result in the disruption of vital functions within the body.
