<<Disclaimer: Verify this information before applying it to your situation.>> I've seen pictures of villi and the surface of the small bowel (both healthy and with celiac), but the scale of the picture is never shown. What's the size of the villi? Millimeters, 1/10 mm, or 1/1000 mm. I have slides from my own biopsy but don't know what microscope magnification to use. Any references?
