The human body is composed of many organ systems, one of which is the reproductive system. The reproductive system of the male is different from the reproductive system of the female. How do they differ?
The female reproductive system consists of a pair of ovaries. Its functions are;
1. To produce an egg cell.
2. to produce the female hormone, progesterone, which determines the secondary sex characteristics.
These ovaries are connected to the uterus through the fallopian tubes. Monthly, each ovary takes turn in releasing a mature egg. This is called ovulation. When the egg cell unites with a sperm cell, this is called fertilization. The fertilized egg is called a zygote. The zygote soon develops into an embryo.
The uterus is a hollow, pear-shaped organ that sheds blood during menstruation. The zygote stays in the uterus until birth. The vagina is a muscular tube. It leads to the uterus. It is called the birth canal. The fallopian tube is the passageway from the ovary to the uterus. The cervix is a muscular ring that connects the uterus to the vagina.
