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. A positive

The term used to describe a pattern of response to restore the body to normal stable level is termed negative feedback.
