50
Q

What are the two types of feedback systems? Differentiate the two.

  • Positive feedback “strengthens” or reinforces a change in one of the body’s controlled conditions.
51
Q

When blood glucose level is increased, the receptors in the pancreas will detect and produce insulin.

A

Negative feedback system

This system just reverses the change in order to bring the body back to homeostasis.

52
Q

In childbirth, the baby’s head in the cervix stimulates the pituitary gland to produce oxytocin which will then stimulate uterine contraction. This will push the baby towards the cervix.

Positive feedback system

This system strengthens or reinforces a change in the body’s controlled condition. In this case, what was strengthened are the uterine contractions.
