0:59 to 2:42 Bonus info: this type of structure made of layers will be present in many organs with a tube structure for example the ureter, ductus deferens, gall bladder (vesica fellea)... just with minor variations so its important to know this basic layering!
2:20 Different parts of the GI track are located in different ares of the body. They can be intraperitoneal, retroperitoneal Primary or Secondary and Subperitoneal. Itraperitonel means that it is in the peritoneal cavity and therefor covered by SEROSA (a thin layer of connective tissue). Retro- (behind) means it is behind the peritoneal cavity, Primary meaning that developed outside the peritoneum and stayed there and secondary meaning that the organ was once covered by peritoneum and later through development the peritoneum got obliterated and now it outside the peritonea cavity therefor covered by ADVENTITIA (It is loose and thicker, irregular collagenous connective tissue composed of fibroblasts, nerves, blood vessels, and other components). Sub= below the peritoneum.
