Explanation:
Detailed explanation-1: -After ovulation, cells in the ovary (the corpus luteum), release progesterone and a small amount of oestrogen. This causes the lining of the uterus to thicken in preparation for pregnancy.
Detailed explanation-2: -The purpose of the menstrual cycle is to prepare the body for a possible pregnancy. During the menstrual cycle, a mature egg is produced by the ovaries and the lining of the uterus thickens to support a possible pregnancy.
Detailed explanation-3: -The menstrual phase occurs at the very beginning of the uterine cycle. It only occurs if no ovum is fertilised. The process begins with the breakdown of the corpus luteum which therefore ceases to produce progesterone.
