1. Explain why homeostasis is important to your body's functioning.
this is very important for our body, for it to function properly because it is what helps stabilized the body temperature.
2. Give three examples of ways your skin helps mantain homeostasis in your body?
this is like a guard that protects your body from foreign particles,temperature is the most important because it helps protect inside organs from cold that is in the envirorment.
a. acts as a physical barrier against dirt and microorganisms entering the body
b. the skin layer helps protect the internal organs that way keeping them safe so they can work.
c. helps stimulate the temperature. and provides physical barrier for any external foreign particle.
3. Explain one way that your body maintains a constant temperature while outside on a cold day.
when you are exposed to cold that is in the envirorment, you involunatrily start to shake uncontrollably, till the contraction of your skeleton muscle release het that warms your body and then it stops the shivering.

1. Why is homeostasis important to your bodies functing?
Homeostasis is important because it is a mechanism which maintains a constant body environment for optimum body function. An example of this can be the heart which pumps blood faster to maintain the body at a certain temperature.Then the receptors in the skin signal or show a heat increase and send a signal to the hypothalamus which is the indicator. As a result you get vasodilation, in other words your hair lies flat on the skin, sweating and so on. This is important to a healthy function body because heat affects proteins for example. Say some hormones have a narrow optimum temperature, if it were to stay constantly high, then the hormones wouldn't function properly same goes for enzymes and a disordr might happen.
2. Give three examples of ways your skin helps mantain homeostasis in your body?
The skin acts as a protective shield for your body protecting it against foreign particles. The temperature would be the most important thing your skin helps regulate because without it humans would be like cold blooded animals, the same temperature as their enviroment.

- It acts as a physical barrier against dirt and microorganisms entering the body. Whenever you get hurt or cut it creates a scar tissue to keep the microorganisms out of the body.
- Its skin layers helps protect the internal organs, that way keeping them safe. If you get cut they will create some sort of regenerating tissue to keep all the internal organs safe.
- Reacts to stimuli when there is a change in body temperature. Your hairs drop so you sweat and that way keep up to the temperature until you are dehydrated.
3. Explain one way that your body maintains a constant temperature while outside in a cold day?
Shivering is one of the reactions that the body makes in a cold day. The muscles contract and releases heat in the body.
An example is when you are outside on a cold day your body keeps you warm by pulling cappilaries and small blood vessels in closer to your body in order to help keep the more important internal organs (heart, lungs, etc.) warm and functoning properly.Thats why your fingers and toes get cold first, your body realizes they are not of nearly the same importance as your vital organs.

2. Give three examples of ways your skin helps maintain homeostasis in your body.
When you sweat the skin is helping you cool dow.
After you sweat, the sweat is turned into vapor and it dries from your skin, so heat is being absorbed. When its hot, your body opens the pores to release heat, and when it cold the pore get smaller to keep heat in.
Also the nerves on your skin let you know when you being touched and it causes reactions to know when something is cold or hot.
