Detailed explanation-1: -Ampulla: The major channel in your fallopian tube, located in-between the infundibulum and the isthmus. Fertilization most often takes place in the ampulla.

Detailed explanation-2: -The fimbria are connected to a portion of the tube called the infundibulum which pushes the ovum into the ampulla. The ampulla is the widest portion of the Fallopian tube, making it a common place for sperm to meet egg and fertilization to occur.

Detailed explanation-3: -As mentioned previously, fertilization occurs in the ampullary segment of the fallopian tube. Transit time of the zygote from the ampulla to the ampulla-isthmic junction is approximately 30 hours, after which the zygote remains in the isthmus another 30 hours before resuming transit through the isthmus.

Detailed explanation-4: -The ampulla is typically where the sperm are met and fertilization occurs; meiosis II is promptly completed. After fertilization, the ovum is now called a zygote and travels toward the uterus with the aid of the hairlike cilia and the activity of the muscle of the fallopian tube.
