True or False:
Homeostasis is NOT a dynamic equilibrium of the internal environment.
False
- Homeostasis is a dynamic equilibrium of the internal environment. All body systems contribute ot homeostasis, by the nervous and endocrine systems are most important. Homeostasis is necessary for health.
Name the 3 control mechanisms of the body that work together during homeostasis.
- receptor(s)
- control center
- effector(s)
__________ __________ _________ reduce the effect of the original stimulus, and are essential for maintaining homeostatic control
- Negative feedback mechanisms
Body temperature, heart rate, breathing rate and depth, and blood levels of glucose and certain irons are regulated by negative feedback mechanisms.
_________ ____________ __________ intensify the initial stimulus, leading to an enhancement of the response during homeostatic control.
