 * Pathway of the egg cell**

The egg cells are produced in the **ovaries.** When a female begins puberty, she will begin to ovulate. (Ovulation) __Ovulation__ is the process of releasing a mature egg cell (ovum) from an ovary. This process typically occurs every 28 days for the average adult female. Once the egg cell (ovum) has been released by the ovary, it is scooped up by the fimbria. **Fimbria** are fringe-like projections around the ovary that help ensure the egg makes its way in to the fallopian tubes. Once the egg is in the fallopian tubes, it makes its journey to the uterus. The **fallopian tubes** have two main jobs: (1) deliver the egg from the ovary to the uterus, and (2) fertilization of the egg cell occurs in the fallopian tubes. Fertilization, as is pertains to the reproductive system, is the union of the sperm and egg cell into 1. The union of an egg cell and sperm cell is known as an embryo.

//__**Typically, an egg cell is not fertilized by a sperm cell. If an egg cell is not fertilized;**__// It begins to break down and make its way into the uterus. The uterine lining (nutrients and blood need to help the upcoming baby) is created through a hormone known as progesterone. The uterine line breaks down and the egg as well as uterine lining leaves the body **(uterus - cervix - vagina)** through the process known as menstruation (female period). __Menstruation__ is a process that occurs roughly every 28 days in women.

//__**If the egg cell is fertilized;**__// It will travel to the __uterus__ and will implant itself along the uterine wall. The uterine lining (nutrients and blood need to help the upcoming baby) is created through a hormone known as progesterone. Roughly ever 28 days, a woman will produce a uterine lining need to nourish a potential baby. Over the course of 9 months, an embryo will develop into a fetus (2 months) and fetus eventually develops into a baby (7 months).
