Oviduct is an environment for sperm capacitation , fertilization , embryo development and transport . Its rear wall : serosa , smooth muscle and mucous membrane , covered with cylindrical epithelium . It is divided into three cell types . The proportion varies in different parts of the fallopian tube. The first is the snapshot cells , which determine , among other things gametes and embryo transfer in the light of the fallopian tube. The second type is a secretory cells that produce and secrete specific glycoproteins . Third cells are przypodstawne . The mucous membrane is subject to cyclical changes associated with the change of the concentration of sex steroid hormones in the course of the menstrual cycle . In its morphology identified eight phases: 1 preciliogenna , 2 ciliogenna , 3 urzęsienia with a predominance of cells urzęsiających over urzęsionymi , 4 urzęsienia ciliated cells predominantly over urzęsiającymi to 5 ciliated cells of the secretory activity of the secretory cells , 6 early regression , 7 late regression , 8 complete regression . An important for the normal function of the fallopian tube is also a reproduction process tubal fluid , consisting of fallopian tube epithelial cell secretion , peritoneal fluid , and the filtrate blood vessels. Its composition and quantity are dependent on the amount of sex hormones. Muscular mucosa and play an important role in the transport of ova and embryos . In addition urzęsieniem snapshot cells are important oviduct smooth muscle contraction , which are dependent on the stimulation of receptors a and b , while the number of estrogen and progesterone. Knowledge of the role of the oviduct in the process of reproduction , as well as its correct anatomical structure is important in assessing the significance of morphological changes were noticed prior to the origin of tubal infertility treatment .
