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 form their peers.

Concept Check 27.3


Concept Check 27.3

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

Homeostasis helps maintain a steady temperature in your body of about 37°C or 98.6°F. When the body is too cold the homeostasis helps the body warm up and when the body is too warm the homeostasis helps the body cool it down. Without the homeostasis in you body, the body would not be able to function properly. Without functioning properly and maintaining the right temperature inside the human body, you would die.

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

  • The skin provides a physical barrier against dirt and microorganisms entering your body.
  • Its layered construction also helps to insulate the body on cold days and to cushion internal organs against physical injury. Your skin further helps maintain homeostasis by responding to such stimuli as slight changes in body temperature and water content.
  • The skin also helps when the body temperature begins to rise above normal, you respond in part by sweating through pores in your skin.
  • Perspiration also cools the body when is to warm. As the sweat is turned to a vapor heat is absorbed from the body.

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

Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when temperature surrounding is very different.

Thermoregulation helps the body temperature keep constant and it helps adapt to the temperature of the environment. It helps change its body temperature according to the temperature outside of its body.

1. Homeostasis is important for are bodies, becasue it is what contols the stability of temperaturas in are body, and because this type of tissue also can olny survive, and live at a certain temprature

2. It helps protect the organs.

It makes sweat, this way are body is capable to cool off.

Goosebumps are created, this Waite body heats inside.

3. One way in wich the body mantains a temperature, is when the pores are joined close together, this way the pores help in mataining the heat inside are body.
