Homeostasis and Negative/Positive Feedback
Guided Notes
3 key concepts
- 1
Homeostasis is the state of balance in the body, ensuring that conditions like blood pH, blood glucose, and internal body temperature remain within a certain range.
- 2
In negative feedback, a variable triggers a counteracting response to return to a set point, while in positive feedback, the variable is intensified instead of counteracted.
- 3
An example of positive feedback is the birth of a human baby, where pressure on the cervix leads to more hormone release and stronger uterine contractions.
