Question

Positive feedback is necessary in which of the following situations?
A)Blood pressure

Positive feedback is necessary during childbirth because the stretching of the cervix causes the release of the hormone oxytocin, which enhances contractions, leading to further cervical stretching and increased oxytocin release until the baby is delivered.
