A human body cell would have 46 chromosomes. Since a human egg cell is a reproductive cell (sex cell), it would contain only half the number of chromosomes as a body cell. Thus, a human egg cell would have 23 chromosomes. A sex cell has half the number of chromosomes for a good reason. When two sex cells reproduce, they combine to form double the number of chromosomes. So when two cells with 23 chromosomes each reproduce, the offspring would have 46 chromosomes.
Female Reproductive System. From the top of the uterus extend the fallopian tubes, which lead backward and downward to the ovaries. These are the two small sacs that contain the eggs. A woman is born with about 400,000 eggs. Each month during her reproductive years, usually only a single egg, or ovum, matures.The egg matures inside a follicle within an ovary. At midcycle, the egg is released from the follicle in a process called ovulation. The egg then enters and travels down one of the fallopian tubes toward the uterus.he egg matures inside a follicle within an ovary.
