Correct answer: C. Fertilization
- A. Ovulation
- B. Implantation
- C. Fertilization
- D. None of these
Explanation
The oviduct, also known as the fallopian tube, is specialized for the transport of eggs (or ova) from the ovary to the uterus. It plays a crucial role in the female reproductive system. After ovulation, when an egg is released from an ovary, the oviduct captures the egg with its fimbriae, which are finger-like projections at the end of the tube. Cilia, tiny hair-like structures lining the walls of the oviduct, help move the egg along the tube toward the uterus. Fertilization typically occurs in the oviduct if sperm is present. If fertilization occurs, the resulting zygote (fertilized egg) begins to divide and forms a blastocyst. The oviduct continues to transport the developing embryo toward the uterus, where implantation can take place.

About Reproduction
Human reproduction covers the male and female reproductive organs, gamete formation, fertilization, implantation and hormonal regulation. The menstrual cycle includes ovarian and uterine changes controlled by pituitary and ovarian hormones, while sexually transmitted diseases are studied through their causes, transmission, symptoms, prevention and effects on fertility.
