The diagram shows a simple outline
of the female reproductive system. What number indicates the
vagina?
Let’s go over the function of each
of these structures in the female reproductive system in order to answer our
question. We’ll start with the ovaries,
indicated as number 5. These are the organs responsible
for making an egg cell, or ovum. Each month, a single ovum is
released from the ovaries by a process called ovulation. This egg cell is released to a part
of the female reproductive system called the Fallopian tube, sometimes called the
oviduct. This is indicated by the number
1.
The ovum moves along the Fallopian
tube where it can combine with, or be fertilized by, a sperm cell. Sperm can be introduced after
sexual intercourse. The fertilized ovum continues to
move along the Fallopian tube toward the next structure called the uterus. This is represented by number
2. Inside the uterus, a fertilized egg
cell can implant into the uterine lining. This is what starts a
pregnancy. In the uterus, the baby can develop
until it’s born.
The cervix is a muscular ring of
tissue that can hold the baby in place while it’s developing. We can see the cervix as number
3. And finally, number 4 indicates the
vagina. This is a muscular tube that is
involved in sexual reproduction. Here is where semen can be
deposited, which contains sperm cells that can fertilize the ovum. Therefore, the number that
indicates the vagina is number 4.
