Homeostasis - Nicholas Smith

Homeostasis
Main Ideas:
- The ability to maintain a stable internal environment
- Body Regulations: Temperature, Heart Rate, pH, Lung flow, Sugar, Insulin, Glucose, Water Balance
- pH control uses a buffer: a solution that resists the change in pH, usually a weak acid/base
- Glucose Levels Control - release of insulin when glucose levels are high, body signals liver to break down glycogen when glucose level are low.

- metabolism: must consume food, blood vessel dilation and constriction, hair and fat, shivering, lay out in the sun or sit by a fire, sweat 

I've known a little bit about Homeostasis from the past but what really surprises me is that it can control multiple things in your body and not miss a beat, for example it can regulate your body's internal temperature and maintain a normal heart rate. Homeostasis occurs within all organisms and the body needs structure like this in order for survival, if something were to change in one area then everything changes. I really liked researching Homeostasis and reading how it can control body regulations and adapt to a certain environment or lifestyle that you train your body to perform at, say as an athlete or if you live in a cold environment. I think Homeostasis can be used to make a baseline on where the human body needs to be in order to be healthy or in order to prepare or train the body to adapt to new conditions.
