Comments "...[researchers] estimate that the gastric pits increase the macroscopic surface area of the stomach mucosa by some 20% to 25%. There are but few microvilli on the surface cells of the gastric epithelium, and the area enlargement from these is negligible. Including the gastric pits, [they] therefore estimate the mucosal surface area of the postprandial gastric mucosa in vivo in the order of 500 cm^2. This figure includes the rugae which unfold when the stomach distends."
