Homework final

My other post was missing a question

1. Explain why homeostasis is important to your body's functioning.

For our organs to work, and our cells to live, they have to be kept with in a set of conditions. In homeostasis, the internal conditions of the body are kept constant. That way, all the systems of your body can function properly. Additionally, the ability to keep homeostasis is essentatial for survival and health.

2. Give an example of an organ that exchanges chemicals, and explain how its structure allows this.

The lungs, preform the exchange of oxygen and carbon dioxide between the blood and the outside air. The structure of capillaries in our lungs fits their function because that way their is a larger surface for chemical exchange. These capillaries are vere tiny, and there are many of them.
3. Give three examples of ways your skin helps maintain homeostasis in your body.

• Seat glands produce sweat as a response to hot outer conditions in order to keep inner temperature.
• The skin serves as a physical barrier against dirt, viruses, and harmful microorganisms that may infect and harm the body.
• The skin provides insulation from extreme outer temperatures and cushion to avoid physical injury of organs.

4. Explain one way that your body maintains a constant temperature while outside on a cold day.

As a response to the stimulus of cold weather, you shiver. When you do so, your skeletal muscles contract. Thus, that contraction produces heat that stabilizes body temperature..
