Generally, the body is in homeostasis when its needs are met and its functioning properly.
The resulting cardiac rate or pulse rate, therefore, is maintained in a state of dynamic constancy by negative feedback loops initiated by sensors in response to changes in blood pressure and other factors.earning objectives for this lab exercise. 1.
