1. Explain why homeostasis is important to your body's functioning.
It's important because it maintains the adequate conditions, such as temperature, for tissues to survive

2. Give an example of an organ that exchanges chemicals, and explain how its structure allows this.
Lungs: interstitial fluid allows oxygen to travel through empty spaces between cells in tissues so cells can oxygenate and produce cellular respiration; CO2 is released by the same way.

3. Give three examples of ways your skin helps maintain homeostasis in your body.
Sweat avoids overheat, because it cools skin protecting it with the evaporation.
Hairs in the skin control temperature and protects skin from dirt.
Shivering is a response for maintaining temperature..


4. Explain one way that your body maintains a constant temperature while outside on a cold day.
Shivering maintains temperature inside body. Another way are the goose bumps created, they protect temperature from outer cold.
