The peritrophic matrix (from the prefix peri-, meaning around, and -trophic, referring to nutrition(food)) or peritrophic membrane is a semi-permeable, non-cellular structure which surrounds the food bolus in an organism's midgut. Although they are often found in insects,[1] peritrophic matrixes are found in seven different phyla.[2] The peritrophic matrix serves several functions, including improvement of digestion, protection against mechanical and chemical damage and serving as a barrier to infection by pathogens.[3] Such peritrophic envelopes are also of great ecological importance in marine environments.
