Oviducts (uterine tubes or Fallopian tubes) -- bilateral, first part of genital tract; site of fertilization and transport of early embryo to uterus.

Examine sections of the oviduct and identify the mesentery, highly vascularized serosa, and the well-developed muscularis, and the very highly folded mucosa.

Examine the simple columnar epithelium at higher power and note the presence of two cell types:

• Ciliated cells and
• Slightly taller non-ciliated secretory cells.

What are the functions of the cells lining this region of the oviduct?

What two histological features of the oviduct relate to the movement of its contents?

Now for the uterus.
