Lab 1: Homeostasis Background Information: Homeostasis is the existence of a stable environment in the body for survival. This process is always regulating bodily functions in order to keep the body in optimal condition. When conditions change a receptor senses and sends a message to a control center. The control center processes the information and sends an appropriate command to effectors. These effectors will respond to the command which will stimulate a positive or negative response.

Homeostasis Lab: The Effects of Exercise on Homeostasis Lab Write Up Introduction: The purpose of this lab is to discover the effect that various levels of exercise have on specific body parameters such as heart rate‚ body temperature‚ perspiration level‚ body color‚ and breathing rate. Homeostasis will be monitored to calculate the change in such body parameters. To find this information the subject will exercise for a controlled periods of time. At each rest‚ the subject will be recorded upon
