Model Answer
Path of sperm from vagina to oviduct:
Vagina → Cervix → Uterus → Oviduct (Fallopian tube)
During sexual intercourse, sperms enter through the vaginal passage. They travel upward through the cervix (the opening of the uterus into the vagina), into the uterus, and continue upward into the oviduct (fallopian tube), where they may encounter the egg and fertilisation takes place.

Explanation
- The examiner expects all four structures named in correct order — vagina, cervix, uterus, oviduct/fallopian tube. Missing any one costs a mark.
- The passage explicitly states: "The uterus opens into the vagina through the cervix" and "sperms enter through the vaginal passage… reach the oviduct." Use these exact structural names.
- "Oviduct" and "fallopian tube" are interchangeable — either is accepted.
- Do not add extra structures not mentioned in the passage (e.g., do not mention vas deferens, which belongs to the male system).
