Detailed explanation-1: -The release of oxytocin from the posterior pituitary gland during labor is an example of positive feedback mechanism. Oxytocin stimulates the muscle contractions that push the baby through the birth canal.

Detailed explanation-2: -Examples of processes that utilise positive feedback loops include: Childbirth – stretching of uterine walls cause contractions that further stretch the walls (this continues until birthing occurs) Lactation – the child feeding stimulates milk production which causes further feeding (continues until baby stops feeding)

Detailed explanation-3: -Explanation: Contraction of the uterus during childbirth causes the release of oxytocin, which stimulates stronger contractions of the uterus, causing more oxytocin release. This perpetual cycle results in a positive feedback response.
