MICROANATOMY

Detailed explanation-1: -Once inside the walls of the fallopian tube, muscle contractions push the egg gently towards the uterus. The egg will either meet sperm on its journey through the fallopian tube and fertilisation will happen, or it will arrive in the uterus unfertilised and be absorbed back into the body.

Detailed explanation-2: -When an egg pops out of an ovary, it enters the fallopian tube. Once the egg is in the fallopian tube, tiny hairs in the tube’s lining help push it down the narrow passageway toward the uterus.

Detailed explanation-3: -After the egg leaves the ovary, the walls of the follicle again close, and the space that was occupied by the egg begins to fill with new cells known as the corpus luteum. The corpus luteum secretes the female hormone progesterone, which helps to keep the uterine wall receptive to a fertilized egg.
