What are fallopian tube why do we need fallopian tubes?

Ovarian connector: Fallopian tubes connect the ovaries where eggs are kept and released to the uterus where eggs meet sperm, implant and develop into babies.

Catch: The fimbria in the fallopian tubes are the catchers of the eggs. Once caught the eggs travel down the tube to meet/connect with the sperm to form the embryo. The cilia in the tube then move the embryo into the uterus to implant. Without the tube pregnancy is not possible under natural circumstances.
