Document Summary

Describe how positive feedback loops help to expel a baby from the womb during labour and delivery. Ensure that you describe the components of a feedback loop and indicate which organs/structures act as these components in the example given above. Be sure to describe how the feedback loop is interrupted (i. e. how a return to homeostasis is achieved). Is the property of a system in which variables are regulated so that internal conditions remain stable and relatively constant. A series of wheels and wheels you have in your body, constantly turning to stay imbalance. A turning in one effects the turning of the other. When you lose the ability to change, you lose the ability to live. The cervix stretches, or dilates, as labor begins. Pressures sensitive receptor cells in the cervix detect the stretch. These receptors send nerve impulses to the brain (the hypothalamus) [control center: figures out what to do when the stimulus is detected].
