Answer» (a) Ovaries: During the first phase of menstrual cycle, growth of follicles occur and primary oocyte matures in the follicle. The mature Graafian follicle bursts to release the ovum. In luteal phase, the remaining follicle forms corpus luteum, an endocrine gland that produces progesterone. (b) Uterus: The inner walls of the uterus are highly vascularised and muscular in nature and is known as endometrium. This wall takes active part in menstrual cycle because it breaks down due to the lack of progesterone. As a result, bleeding occurs. In the follicular phase, uterus enlarges in size. (c) Fallopian tube: The wall of the fallopian tubes thickens and its cilia and their movements are increased.
