An egg cell that is not fertilized follows which path?
a. Ovary, oviduct, uterus, cervix
b. Ovary, uterus, oviduct, cervix
c. Oviduct, ovary, cervix, uterus
d. Oviduct, ovary, uterus, cervix
e. Ovary, oviduct, cervix, uterus

Verified step by step guidance

1. Understand the anatomy of the female reproductive system: The key structures involved in the movement of an egg cell are the ovary, oviduct (also called the fallopian tube), uterus, and cervix.
2. Recall the function of the ovary: The ovary is where egg cells are produced and released during ovulation.
3. Identify the role of the oviduct: After ovulation, the egg cell travels through the oviduct, which is the site where fertilization typically occurs if sperm is present.
4. Determine the path of an unfertilized egg: If the egg is not fertilized, it continues its journey to the uterus, where it is eventually shed during menstruation.
5. Recognize the final step: The cervix is the lower part of the uterus that connects to the vagina, and it is the final structure the unfertilized egg passes through before leaving the body.

Key Concepts

Ovarian Cycle

The ovarian cycle involves the maturation of egg cells (oocytes) within the ovaries. Each month, a follicle develops and releases an egg during ovulation. If the egg is not fertilized, it will not proceed through the reproductive tract, making understanding this cycle crucial for answering the question.

Reproductive Tract Pathway

The reproductive tract pathway describes the route an egg cell takes through the female reproductive system. After ovulation, if the egg is not fertilized, it typically moves from the ovary to the oviduct, but without fertilization, it will not reach the uterus. This pathway is essential for determining the correct answer to the question.

Menstrual Cycle and Shedding

The menstrual cycle prepares the uterus for potential pregnancy. If fertilization does not occur, the egg and the uterine lining are shed during menstruation. This process highlights the fate of the egg cell and the importance of understanding the timing and sequence of events in the reproductive cycle.
