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.

Activity 1, Section 27.3

1.Explain why homeostasis is important to your body's functioning.
Homeostasis is the internal stability temperature in our body, it’s extremely important because our body can only function as it should between a small range of conditions. If our body can’t maintain stability within those conditions, between the set point, our tissues would not survive.

2.Give three examples of ways your skin helps maintain homeostasis in your body.• skin provides a physical barrier against dirt and microorganisms
• skin has a layered construction so it helps your body isolate from cold temperatures
• skin helps cushion internal organs in our body to protect us from possible injuries.

3.Explain one way that your body maintains a constant temperature while outside on a cold day.
The fast contractions of skeletal muscles release heat, helping your body maintain its temperature; this mechanism is called shivering.
