Solution

Answer: The human female gonads are ovaries. A maturing egg in the ovary is present in a sac of cells called follicle (1). As the egg grows larger, the follicle enlarges and gets filled with a fluid and is now called the Graafian (2) follicle. The process of releasing the egg from the ovary is called ovulation (3). The ovum is picked up by the oviduct funnel and fertilisation takes place in the oviduct (4). In about a week the blastocyst gets fixed in the endometrium of the uterus and this process is called implantation (5)

When a female child is born, her ovaries already contain thousands of immature eggs (or ova) contained to immature structures A. On maturing, A bursts open and an egg shoots out of the ovary in a process called B. The process B starts in the females at puberty and occurs again and again after a time period x. Before every occurrence of process B, the inner lining of the uterus becomes thick and soft with lots of blood vessels in it. When the egg cell gets fertilised by a sperm, then an event C occurs in the life of mature human female which lasts for time period y leading to the birth of a baby. If, however, the egg cell released by the ovary does not get a sperm to fuse with, then the thick and soft inner lining of the uterus breaks down and comes out of the female's body in an event called D. The occurrence of event D is controlled by chemical substances E.
