Which part of fallopian tubes fertilization occur?
Solution:
- Fertilisation occurs in the female reproductive system, specifically in the junction of ampulla and isthmus of the fallopian tube, when a sperm fertilises an egg.
- The ovum produced by the ovary is picked up by the fimbria and transported into fallopian tube.
- The ovum reaches ampulla and then remains in the ampullary isthimus junction and is viable for 18 to 24 hours.
- If the fertilisation does not take place inside the fallopian tube within 24 hours, the egg loses its viability and gets destroyed.
