What is the function of the fallopian tubes in the female reproductive system?

The function of the fallopian tubes, also known as oviducts, is primarily to transport the egg from the ovaries to the uterus and facilitate fertilization. After ovulation, when an egg is released from the ovary, it is captured by the fimbriae (the finger-like projections) of the fallopian tube. The fallopian tubes are the site where fertilization typically occurs; sperm travel through these tubes to meet and fertilize the egg. Once fertilization happens, the developing embryo travels down the fallopian tube to reach the uterus, where it can implant and continue developing.

Other options pertain to different aspects of female reproductive health. The production of estrogen and progesterone is primarily carried out by the ovaries, not the fallopian tubes. Providing oxygen to the fetus is a function that occurs in the placenta during pregnancy, not in the fallopian tubes. The support of the uterus during pregnancy involves various structures such as ligaments and the pelvic floor, rather than the fallopian tubes themselves. Thus, the correct choice focuses on the essential role of the fallopian tubes in egg transportation and fertilization.
