Question
Fertilisation takes place in __________.
Solution
Fertilisation takes place in the fallopian tube.
Explanation:
During copulation (coitus), semen is released by the penis into the vagina (insemination). The motile sperms swim rapidly, pass through the cervix, enter the uterus and finally reach the ampullary region of the fallopian tube. The ovum released by the ovary is also transported to the ampullary region, where fertilisation takes place.
