Question

During childbirth, a woman will experience muscle contractions in her uterus in response to pressure generated by the fetus. As the fetus moves and generates more pressure, the number of contractions increases, in a positive feedback loop. What is the difference between this and the negative feedback loops you've learned about?

Answer 1

Answer:

here

Explanation:

In a negative feedback loop, an increase in a factor will result in a change in the body that'll reduce the value of this factor to the set point.

For example, an increase in the blood glucose levels after a meal will cause an increase in the levels of insulin in the blood which will lower the glucose levels.

However, in this example, an increase in the pressure generated by the fetus also increases the frequency of uterus contractions. So the more the pressure, the more the contractions.
