The Fallopian tube's inner mucosal layer is responsible for delivering gametes and embryos, as well as tubal fluid discharges. Epithelial cells and the lamina propria mucosa, a network of connective tissue with a mixed cell population, make up the endosalpinx. Ciliated epithelial cells and nonciliated secretory epithelial cells make up the epithelial tissue that lines the inner surface of the Fallopian tube. The lamina propria, which is made up of fibroblasts, immune cells, and progenitor cells, lies beneath the epithelial lining. To attain a high fluid secretion rate, the mucosal layer produces dense internal folds, increasing the surface area of epithelial cell lining.
