Homeostasis

Homeostasis

• allows for a wildly fluctuating internal environment

• is impossible in vertebrates

• is the maintenance of a relatively stable internal environment and often incorporates a form of feedback regulation

• is the maintenance of a relatively stable external environment and often incorporates a form of feedback regulation

Which of the following is not regulated by homeostasis?

• body temperature

• blood sugar

• blood pH

• body movements

The group of organisms that use the process of homeostasis includes

• mammals, only

• animals, only

• plants and animals

• all living things

When glucose levels in the blood rise, your brain sends a signal to your pancreas. The pancreas releases insulin, which opens channels in cell membranes to allow glucose to enter the cell, lowering blood sugar levels.
