Question

Quizplus · Accepted Answer

Oxytocin is involved in a positive feedback loop during labour and delivery. As the baby moves downwards through the birth canal, pressure is applied to the cervix which triggers the release of oxytocin. This hormone then stimulates contractions of the uterine muscles, which pushes the baby further down and applies more pressure to the cervix, causing more oxytocin to be released and further stimulating contractions. This positive feedback loop continues until the baby is born.
