Homeostasis

One of the most common examples of homeostasis is body temperature. When your body temperature rises above normal, how does your body respond?

• shivers

• sweats

• coughs

When your blood sugar is too high, what hormone is released?

• glucagon

• insulin

What is the evaporation of a liquid to cool the body?

• Shivering
• Sweating
• Vasodilation
• Vasoconstriction

If the environment gets cold, we will often shiver in order to:

• keep body temperature the same as the external temperature
• decrease body temperature
• increase body temperature
• regulate blood pressure

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

Why is the sensation of thirst important to maintaining homeostasis?

• Water removed by the kidneys must be replaced

• Oxygen cannot diffuse into cells if a person is dehydrated

• Water molecules are needed to carry carbon dioxide waste to the kidneys

Why does pulse rate increase during exercise?

• Oxygen and carbon dioxide must be removed from the body ASAP

• Gas exchange must happen more quickly than when a person is at rest

• Oxygen must be moved to the lungs and carbon dioxide must be moved to cells more quickly

• Carbon dioxide must be moved to the kidneys to be excreted
