What are the 4 muscle layers of the stomach from inside to outside?
The GI tract contains four layers: the innermost layer is the mucosa, underneath this is the submucosa, followed by the muscularis propria and finally, the outermost layer – the adventitia. The structure of these layers varies, in different regions of the digestive system, depending on their function.
What is the outside of the stomach made of?
