Summary
A surface film with a thickness of 280–570 Å covers the mesothelium of serous membranes in the rat. This film can be stained with ruthenium red. Its considerable water-binding capacity produces the reflecting surface of the serous membranes. The friction of the organs is thereby greatly reduced. Only a small amount of serous fluid must be produced to keep the surface moist. The glucosamino glycans of the surface film are probably synthesized by the mesothelial cells.
