Question

describe the changes to the uterus and ovaries during one menstrual cycle

Answer 1

During the uterine cycle, the womb gets prepared and chances of pregnancy increases. While during the ovary cycle, the egg is formed and when it is mature it is released  into the outer end of the fallopian tube at ovulation. Before the ovary cycle, the oestrogen level gets raise. 

Answer 2

The regular natural change that occurs in the female reproductive organs is known as the menstrual cycle.
The lining of the womb or endometrium is prepared for a possible pregnancy during the 'uterine cycle'. During the 'ovarian cycle' an immature egg, primordial follicle or ovum develops in the ovary and is released into the outer end of the fallopian tube at ovulation when it is mature.
