The reproductive system is essential in that it allows for
the continuation of the human species. This system is different in both males and
The role of the males reproductive system is to
manufacture sperm and then to deliver them to the females reproductive tract where
fertilization may occur. The role of the females reproductive system is to
accept the males sperm and carry it to an egg to be fertilized. If fertilization
occurs the female reproductive system is designed to nurture and care for the cell that
will soon grow into a baby.
The sperm is produced in the males
testis and then travels through a series of ducts to reach the exterior of the body.
The eggs are produced in the ovary of a female. When a egg is to be expelled or
ovulated a "blister" forms on the ovary. When the blister
bursts the egg is collected by the ends of the fallopian tubes and travels through them
where it can be fertilized by a single sperm.
If an egg is fertilized it travels
down into the uterus and embeds in the wall. There it divides rapidly and the cells
begin to specialize into the different organs of a pregnancy. Some of the cells form
the amniotic sac while some form the placenta and the umbilical cord. Only a small
number of these cells will eventually form the fetus.
