The serosa or fibrous layer of the gastrointestinal tract

The serosa layer is a smooth tissue membrane of mesothelium lining the contents and inner walls of body cavities, which secrete serous fluid to allow lubricated sliding movements between opposing surfaces. It is the outermost layer of the gastrointestinal tract and is composed of a secretory epithelial layer and a connective tissue layer underneath . The epithelial layer, known as mesothelium, consists of a single layer of avascular flat nucleated cells (simple squamous epithelium) which produce the lubricating serous fluid . The connective tissue layer provides the blood vessels and nerves for the overlying secretory cells, and also serves as the binding layer which allows the whole serous membrane to adhere to organs and other structures . #serosalayer
