Oviduct

The (also called Fallopian or uterine tube) transports ovum from the ovary to the uterus. Its wall is composed of three layers:

- exhibits thin that project into the lumen. These folds are a distinctive characteristic of the oviduct.
- Simple Columnar Epithelium - consists of two types of cells:
  - - the cilia wave towards the uterus to help propel ovum or fertilized zygote to the uterus.
  - - secrete fluid that provides nutrients for the ovum or fertilized zygote.
- - connective tissue that supports the epithelium and contains blood vessels and nerves.
- consists of an inner circular or spiral layer and an outer longitudinal layer whose peristaltic contractions help propel the ovum or fertilized zygote to the uterus.
Serosa - composed of a simple cuboidal epithelium (or mesothelium) supported by a thin layer of connective tissue.

Unlike many tubular tissues, there are no goblet cells or glands in the epithelium or any other glands in the wall of the oviducts.
