Consist of: epithelium , lamina propria (glues to epithelium) , & muscularis mucosa (smooth muscle folding) Job: lubrication, aid in coating so sto(cid:373)ach does(cid:374)(cid:859)t digest itself: submucosa. Inner circle & outer longitudinal to help w/ peristalsis. Job: is to contract and push food through gi track: serosa/ adventicia. Job: act like saran wrap: coating and providing lubrication (secretes serosal fluid) Mesothelium ct (thin: enteric ns (controlling/coordinating peristalsis) Have peritoneum on their anterior side only. & an oblique muscular layer (allows twisting to mix food: fundus.
