Positive Feedback in Childbirth Worksheet

This positive feedback worksheet helps students understand how oxytocin regulates childbirth through a clear, step-by-step biological example.

Students are asked to label the stages of a positive feedback loop, reinforcing how signals from the nervous system and hormones work together to intensify a physiological response during labour.

What’s included:

A labelling worksheet explaining the positive feedback loop in childbirth

Key stages covered:

Nerve signals sent from the cervix to the brain

Pituitary gland release of oxytocin

Transport of oxytocin in the bloodstream

Uterine contractions pushing the baby toward the cervix

A fully completed answer key for easy marking

Simple, uncluttered layout suitable for printing or digital classrooms

Learning objectives:

Understand the concept of positive feedback

Describe the role of oxytocin in labour

Link the nervous and endocrine systems

Apply biological knowledge to a real-world physiological process

Suitable for:

Senior secondary Biology / Human Biology

GCSE, IGCSE, or Australian Curriculum Science

Homeostasis and feedback mechanisms topics

Revision lessons, homework, or independent work

This resource is ideal as a low-prep classroom activity, a revision task, or a quick formative assessment to check student understanding of feedback loops.
