KEY CONCEPT Systems interact to maintain
homeostasis.
2
I can describe the interaction between organ
systems in terms of homeostasis.I can describe
the effect of disruption of homeostasis.
3
Each organ system affects other organ systems.

• Organ systems must also work together to keep the

• Organ systems must also work together to keep the
  organism healthy.

• Organ systems work together to produce Vitamin D.
• Thermoregulation maintains a steady body
  temperature.

A disruption of homeostasis can be harmful.

• Homeostasis can be disrupted for several reasons.
  
• sensors fail
• targets do not receive messages
• injury
• illness

• Short-term disruption usually causes little or no
  harm.

• Long-term disruptions can cause more damage.
• Diabetes is a serious long-term disruption of
