Physiology‚ Berry HOMEOSTASIS LAB ACTIVITY Introduction: Homeostasis means maintaining a relatively constant state of the body’s internal environment. The term used to describe a pattern of response to restore the body to normal stable level is termed negative feedback. When a stimulus (environment change) is met by a response that reverses (negates) the trend of the stimulus‚ it is negative feedback. As a result the internal environment is returned to normal. Pulse rate is constantly checked
