 clefts in the interglandular tissue. From this plexus the lymph is 

 carried into larger valved vessels in the submucous coat, and from 

 these, efferent vessels pass through the muscular coat to reach the

serous membrane, underneath which they pass away from the organ. 

 The muscular coat has its own network of lymphatic vessels. These 

 lie between the two principal layers, and their lymph is poured into 

 the efferent lymphatics of the organ. 



The nerves have the same arrangement and mode of distribution 

 as those of the small intestine (see next Lesson).
