What is the main function of the oviduct in the female reproductive system?

The main function of the oviduct, also known as the fallopian tube, is indeed the fertilization of the egg. After the ovary releases an egg during ovulation, the egg is captured by the fimbriae (finger-like projections) of the oviduct. It is in the oviduct where sperm can meet the egg, leading to fertilization. The fertilized egg, now called a zygote, then travels down the oviduct to implant in the uterus.

While the oviduct plays a crucial role in the process of fertilization, the other options pertain to different functions within the female reproductive system. The production of eggs occurs in the ovaries, sperm transport is primarily facilitated by the male reproductive system, and the site of the placenta, essential for fetal development during pregnancy, is located in the uterus, not the oviduct.
