Health blog!

Welcome students to our class blog. We will be using this space for class discussions to examine, evaluate, and share knowledge. Discussions provide opportunities for students to think critically on the topics we will be learning about in Health class. Concepts, assignments, and readings will be used as the basis for our discussions to create a positive learning community in which students are willing to share their ideas and to accept constructive criticism from their peers.

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

Homeostasis controls and maintains an adecuate temperature for your body. It is important since it regulates your body stability. It is essential because if we dont have a regulated internal stability then we develop disorders.

2. Give three examples of ways your skin helps maintain homeostasis in your body.

It maintains homostasis by acting as a barrier that protects your body from microorganisms or factors that affect it. It cushions internal organs making them more inmune to injuries. It responds to stimuli in hot and cold climates. In hot climates muscles relax so they can realese heat. In cold climates muscles contract to maintain heat.

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

Neurons send signal to our molecules that stimulate them and they make our muscles shiver. When we shiver our muscles are producing faster contractions so we can maintain and make heat.

  1. I really like the way you explained the third question. I didn't pay atention to the part that neurons send signals tou our molecules to stimulate them and make us shiver or sweat. Good answers to the other questions.

  2. As Andrea, I also like the way you explained question three because the part of the signals sent when your body responds to stimuli was not so clear. Now I see the connection between this and the way bodies shiver to retain heat.
