Final answer:
After ovulation, the egg is swept into the fallopian tube and takes about one week to travel through it towards the uterus.
Step-by-step explanation:
The journey of an egg through the fallopian tube towards the uterus is a crucial part of the reproductive process. After ovulation, when the egg bursts out of the follicle and through the wall of the ovary, the finger-like projections called fimbrae of the fallopian tube help guide it into the tube. The egg itself is nonmotile, so it relies on the movement generated by the cilia and the contractions of the smooth muscle lining the fallopian tube to move forward. It is estimated that it usually takes the egg or embryo about one week to complete its travel through the oviduct, which includes the portion of the fallopian tube leading to the uterus.
