The Fallopian tube is also called the oviduct or even uterine tube. They are a pair of  muscular, J shaped ,long and skinny ducts in a human female stomach area. They carry male sperm cells to the egg then supply a suitable space for fertilization. The mucous membrane lining the Fallopian tube gives off secretions to help to carry the sperm and the egg and to keep them alive. They carry the egg from the ovary where it is made, to the central channel of the uterus. Each fallopian tube is about 4–5 inches long and about 0.2–0.6 inches in diameter.

 The passage of the tube is lined with a layer of mucous membrane that has a lot of folds and small cone like pieces of tissue. There are three layers of muscle tissue over the mucous membrane. the furthest in layer has winding fibres, the middle layer has circle like fibres, and the outer layer has fibres that end in many branches by the ovaries. This forms a funnel-like depository called the infundibulum. 

Overall the main function are to help in transport and carry of the ovum from the ovary, to the uterus, Carry sperm to the egg and give a healthy place for fertilization and carry the egg to the uterus for fetal growth. If all of this happens correctly and successfully the fetus will grow and a baby will be born in 9 months. Studies look at Fallopian tube health for answers about how fertile a woman may be. it is a very important part of what makes a woman a woman and able to bare children.
