Once labor begins in childbirth, contractions increase in intensity and frequency, causing more contractions to occur until delivery.
the increasing labor contractions of childbirth are an example of what type of regulation?

positive feedback mechanism

Explanation:the body is able to regulate it's internal environment through homeostasis.it usually involves a receptors,an intergration center and an effector.

In positive feedback,the body enhances the initial stimuli and pushes it's level out of a normal range, which is beneficial to the body at the time.this is unlike negative feedback which reduces the stimuli.

During labour,the body releases the hormone oxytocin, which speeds up and increases contractions . this increase in contraction triggers an increase in oxytocin production until the child is born.

This is an example of positive feedback mechanism

it also supports my hypothesis. if you rest first you can squeeze the clothespin more times. from the data i collected the average of the eight people concluded exercise makes your muscles more fatigued and less able to squeeze the clothespin compared to resting before squeezing.

this is math not biology xd
