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.

concept check 27.3

1. Explain why homeostasis is important for your body's functioning
homeostasis is the internal stability of our body it is very important because our tissues can only survive in a narrow range of temperature, and homeostasis keeps the temperature around 37ºc so we can survive.
2. Give three examples of ways your skin helps maintain homeostasis in your body
  • the layered construction of our skin helps insulate the body on cold days.
  • when the external temperature is too hot your skin responds to this stimuli by sweating trought its pores to lower the internal temperature.
  • the skin phisically separates your body from the external envyronment making homeostasis easier.
3. Explain one way that your body maintains a constant temperature while outside on a cold day
on a cold day you shiver so you maintain your temperature, when you shiver your skeletal muscles rapidly contract realising heat so your internal temperature doesn't change.

  1. You clearly responded to all the questions in a very precise way, I liked how you included the fact that we maintain a body temperature of 37 degrees all the time, not depending on the external temp.

  2. The answers are well stated but you could improve by being more specific
