Anatomy and physiology is the study of what
Structure and function
What is homeostasis
The body’s ability to detect change and oppose it to maintain relatively stable internal conditions. loss causes illness or death
What systems are responsible for maintaining homeostasis
Endocrine: responsible for changeover prolonged time nervous:
responsible for change that occurs rapid all
Negative feedback
Keeps variable close to the set point
most important in regulating homeostasis
What are the 3 components of negative feed back
- Receptor: senses change
- Integrating (control) center: processes the infor and directs a response
- Effector: carries out the corrective action to restore homeostasis
What is positive feedback
A self amplifying cycle that leads to greater change in the same direction
(Normal way of producing rapid changes) if unchecked can be harmful
