Glucose Balance in the Body
Learning Objective
I can describe how the body maintains a stable glucose level
Key Concepts
Homeostasis is the state of balance in the body, such as maintaining a certain pH level, blood glucose, and internal body temperature.
Negative feedback is when a variable triggers a counteracting response to return to a set point, while positive feedback intensifies the variable instead of counteracting it.
An example of positive feedback is during childbirth, where pressure on the cervix causes the release of hormones, leading to more contractions and pressure, ultimately helping the baby to be born.
