Welcome to this lesson on the female reproductive system. Today you are going to be learning about the structure and function of the female reproductive system. Specifically, you will learn about:
The female reproductive system is a body system specific to females that plays a role in the development of offspring from the time of conception through birth. Please refer to the diagram below as you work your way through this lesson.
A female has two ovaries, one on each side and the ovaries produce and release egg cells called oocytes. Oocytes are immature egg cells that are produced in the ovaries and they don't become mature unless they become fertilized.
Egg cells, sometimes called gametes, will be released from the ovaries and will move into the oviduct or fallopian tube. As egg cells move through the fallopian tubes they may encounter sperm and this is where fertilization occurs.
From there, regardless if the egg becomes fertilized or not, it will travel toward the uterus. The uterus is the location for the development of a fertilized egg which will eventually become an embryo.
The myometrium is a muscular layer of the uterus and will expand quite a bit if a baby is developing within the uterus, creating room for the developing embryo and fetus.
The endometrium is another component of the uterus and is the inner lining of the it. This is where the embryo would implant if the egg had become fertilized and would began its development.
The cervix is the lower part of the uterus that leads out to the vagina. The vagina is essentially the birth canal and leads from the cervix to the outside. The vagina is essentially where a baby exits the mother and where sperm is first introduced.
Oogenesis is the word used for the formation of an egg and takes place in the ovaries. A matured egg is released into the ova duct and may become fertilized but if it doesn't the egg will still moves toward the uterus. If the egg is not fertilized it will be expelled through menstruation out the cervix and then out the vagina.
This lesson has been an overview on the structure and function of the female reproductive system. Specifically, this lesson focused on the ovaries, the ova duct, the uterus, and oogenesis.
Keep up the learning and have a great day!

The female reproductive system’s primary job is to mature and release ova (eggs) while the secondary functions are to gestate, deliver and nourish the child. The primary organs are the ovaries while the accessory organs are the vagina, cervix, uterus, fallopian tubes and breasts.
Female reproductive organs that produce oocytes.
Cells (eggs in females, sperm in males) which are haploid (contain 23 chromosomes).
Immature egg cells that are released from ovaries.
A duct that connects ovaries to the uterus through which egg cells travel; also called "fallopian tubes".
An organ of the female reproductive system in which fertilized eggs develop into an embryo.
The inner lining of the uterus.
The lower portion of the uterus which opens to the vagina.
The organ of the female reproductive system which serves as the location where sperm enter and also serves as the birth canal.
The process by which egg cells are formed.
