Negative feedback loops maintain homeostasis in the human body. During labour, a positive feedback loop is an integral part of the process. a. What is a positive feedback loop? b. Describe the TWO positive feedback that is used during parturition. Make sure to include both hormones involved in parturition.
Adi S.
During childbirth, a hormone produced by the pituitary gland causes muscles of the mother's uterus (or womb) to contract. The more contractions there are, the more hormone is produced. Which best explains why this occurs? Positive feedback is used to build more contractions. Positive feedback is used to lessen the effects of the contractions. Negative feedback is used to build more contractions. Negative feedback is used to lessen the effects of the contractions.
Anand J.
During childbirth, the hormone oxytocin causes contraction of the uterine wall muscles. As contractions increase, more oxytocin is released from the pituitary, leading to more contractions. This is an example of which mechanism? a. end product inhibition b. negative feedback mechanism c. positive feedback mechanism d. feedback inhibition
