Question

Match the stages of the uterine cycle

A.Proliferative phase
B.Menstrual phase
C.Secretory phase

Answer 1

The stages of the uterine cycle are the menstrual phase, proliferative phase, and secretory phase.

Step-by-step explanation:

The stages of the uterine cycle are as follows:

1. Menstrual phase: This stage generally occurs from days 1 to 5 of the cycle and involves the shedding of the endometrial tissue.
2. Proliferative phase: This phase occurs from approximately day 7 to 14. During this time, estrogen secreted by the maturing ovarian follicle causes the lining of the uterus to grow and thicken.
3. Secretory phase: This is the final phase of the uterine cycle, which typically takes place from day 15 to 28. Progesterone, produced by the corpus luteum in the ovary, stimulates changes in the endometrium, making it more receptive to the implantation of a blastocyst.
