Question

Which shows the pathway of the egg through the reproductive system?

ovary → fallopian tube → vagina → uterus
vagina → uterus → fallopian tube → ovary
fallopian tube → ovary → uterus → vagina
ovary → fallopian tube → uterus → vagina

Answer 1

Answer :-

" ovary → fallopian tube → uterus → vagina " is the correct answer as-

• after being released at the peritoneal cavity after rupture of the ovary's wall, the egg is catched by the fimbriae that is, the finger like projections present at the infundibulum end of each of the two fallopian tubes and these finger like projections push the egg into the fallopian tube after catching it.
• The egg makes it through the fallopian tube by the help of the continuous muscular contractions of the walls of the fallopian tube as the egg itself is not motile by nature.
• From here, regardless of whether the egg gets fertilised or not at the fallopian tube, the final pathway of it remains to go through the uterus, then the cervix and then the vagina.
