ANATOMY AND PHYSIOLOGY 



Like the stomach, it is composed of four coats or tunics 

 mucous, submucous, muscular and serous. 



The mucous coat is the glandular coat; that is, the glands which 

 secrete intestinal juice are imbedded in the mucous coat, and their 

 ducts open on its surface.

 Large intestine thrown upward, small intestine drawn to left. 



In addition, small gland-like bodies of lymphoid structure are scattered 

 throughout this coat. They have no ducts. They are probably lymph 

 nodules the so-called solitary glands. 



The submucous coat bears the fine vessels and nerves which 

 supply the mucous coat. It connects the mucous and muscular 

 coats together.
