What is the structure and function of the reproductive system, and what are the organs involved in the system?

The female reproductive system is composed of two ovaries
to produce ova, or eggs. There are two tubes called oviducts that are connected to the
uterus or womb. The oviduct is where the egg waits to be fertilized by a sperm cell in a
sexually active female. The uterus supports the growth and development of the embryo and
later on, the fetus. The vagina is the birth canal through which the baby is born. There
are hormones called estrogen and progesterone which maintain the menstrual cycle and a
pregnancy if one arises. Males have two testes, which are the essential male organs that
produce both sperm and testosterone, the male hormone. Sperm cells are male gametes that
join with an egg to produce an offspring. There are two vas deferens or sperm ducts that
connect the testes to the urethra, a tube that runs through the penis and is the way for
the sperm to leave the body, via ejaculation. There is a liquid called semen that blends
with the sperm, and is produced by seminal vesicles, prostate gland and cowper's glands.
This liquid aids the sperm's journey to the egg by providing a medium for sperm to swim
in. During sexual intercourse, the penis deposits sperm in the female vagina. If an egg
cell is present in the oviduct and a sperm cell swims up to the cervix, the uterus and
to an oviduct with a waiting egg cell and joins with it, fertilization occurs. These
systems become active after puberty.
