How does the egg move to fallopian tube when it is dischrge by ovary?

The process by which the egg moves from the ovary to the fallopian tube is known as ovulation. Here's a step-by-step explanation of how it occurs:

1. Ovulation: During the menstrual cycle, typically around day 14 (though this can vary among individuals), a mature egg is released from one of the ovaries. This process is triggered by a surge in luteinizing hormone (LH) from the pituitary gland.

2. Graafian Follicle Rupture: The mature egg is contained within a structure called the Graafian follicle. The LH surge causes the Graafian follicle to rupture, releasing the egg into the peritoneal cavity.

3. Cilia and Peristalsis: The fallopian tubes are lined with cilia, tiny hair-like projections, and muscular walls. The cilia create a wave-like motion that helps move the egg toward the fallopian tube. Additionally, the muscular contractions of the fallopian tubes, known as peristalsis, aid in transporting the egg.

4. Fimbriae: The distal ends of the fallopian tubes are called fimbriae. These finger-like projections help capture the egg as it is released from the ovary. The fimbriae are covered in cilia and also contribute to the movement of the egg into the fallopian tube.

5. Tubal Transport: Once the egg is inside the fallopian tube, it continues to be propelled toward the uterus by the cilia and peristalsis. This process of tubal transport can take several days.

During this journey, the egg may encounter sperm if fertilization has occurred. If fertilization occurs, the fertilized egg, now called a zygote, continues its journey through the fallopian tube and eventually implants in the lining of the uterus, leading to pregnancy.
