Intro to Homeostasis

Recall what word describes maintaining a constant internal environment.

• Heterotrophism

• Thermoregulation

• Homologous

• Homeostasis

Recall what thermoregulation keeps constant in the body

• pH

• Water

• Temperature

• Blood glucose

Select the answers that are true for homeostasis:

Select ALL correct options

• Negative feedback systems regulate changes in homeostasis

• Maintains human core body temperature at 35 degrees

• Is a control system that maintains a stable internal environment

• Increased hair growth is an example of homeostasis

Recall what negative feedback means in the context of homeostasis.

• No action is caused by environmental stimulus

• A negative temperature is always maintained

• No feedback is given to the receptor

• The effect of a stimulus is counteracted by a response

Recall what tolerance limits are in homeostatic organisms

• The number of cells that can contribute to homeostasis at any one time

• The restricted range of conditions in which cellular processes can continue

• The most environmental change possible

• The amount of homeostasis that an organism can tolerate
