Oviducts: The oviduct is also known as the fallopian or uterine tube. It is the passageway through which the ovum passes from the ovary to the uterine cavity. The oviducts are part of the genital tract. They have a wall of smooth muscle, an inner mucosal lining and an outer layer of loose supporting tissue (serosa). It provides vital structural and nutritional support for the development of the embryo. They are 12 cm long tubes.

Functions of Oviducts

• The fimbriated end of the fallopian tube receives secondary oocytes from the raptured follicle during ovulation.
• The ampulla part of the fallopian tube acts as a site for fertilization of the ovum by the sperm.
• The formation of cleavage, morula, and blastula of the zygote takes place in the fallopian tube.
• The transportation of blastocyst takes place with peristaltic movement of the fallopian tube.
