Determine whether a positive or a negative feedback mechanism is taking place in each example. Put a plus (+) sign if it is a positive feedback mechanism and a negative (-) sign if it is a negative feedback mechanism. Situations Brief Explanation 21. Luteal phase Follicle changes into corpus luteum resulting to an increase in estrogen and progesterone levels that keeps the endometrium thick. 22. Ovulation 23. Childbirth 24. Lactation 25. Menstruation The dominant follicle releases estrogen which stimulates LH and FSH release to promote further follicular growth. The stretching of uterine walls causes contractions that further stretch the walls. These continues until birthing occurs. Suckling stimulates milk production which causes further feeding (continues until baby stops feeding). Uterine lining sheds due to reabsorption of corpus luteum and decreased level of estrogen and progesterone. Type of Feedback
