What are Pair of slender ducts through which eggs pass from the ovaries to uterus in female reproductive system.?

The pair of slender ducts through which eggs pass from the ovaries to the uterus in the female reproductive system are called fallopian tubes or uterine tubes. These tubes are also known as oviducts or salpinx. They serve as the pathway for the eggs released during ovulation to travel from the ovaries to the uterus.

Here's a brief overview of the structure and function of fallopian tubes:

1. Structure:

- The fallopian tubes are thin, muscular tubes that extend from the ovaries on either side of the uterus.

- Each fallopian tube is approximately 10-12 cm in length.

- The tubes have a funnel-shaped opening near the ovary called the infundibulum, which contains finger-like projections called fimbriae that help capture the released egg.

- The fallopian tubes are lined with ciliated cells that help propel the egg toward the uterus.

2. Function:

- The primary function of the fallopian tubes is to transport the egg from the ovary to the uterus.

- After ovulation, the fimbriae of the fallopian tubes sweep the released egg into the infundibulum.

- The cilia lining the fallopian tubes then create a wave-like motion that helps move the egg toward the uterus.

- Fertilization typically occurs in the fallopian tubes when the sperm cells travel from the vagina and cervix through the uterus to reach the egg.

3. Ectopic Pregnancy:

- Sometimes, the fertilized egg can implant and begin to develop outside the uterus, usually within the fallopian tubes. This is known as an ectopic pregnancy, which can be a serious medical condition.

4. Tubal Ligation:

- Fallopian tubes can be surgically blocked or severed as a method of permanent birth control, also known as tubal ligation.

The fallopian tubes play a crucial role in the process of conception and serve as important pathways for the movement of eggs and the occurrence of fertilization.
