filling with blood of the capillaries during digestion, 

 the villi are thrown into a state of turgescence during 

 this period, in consequence of which the central chyle 

 vessels are kept distended. Absorption is thus 

 greatly supported. The contraction of the muscular 

 tissue of the villi and of the muscular coat of the in-

274. The non-medullated nerves form a rich 

 plexus, called the the plexus tnyentericus of Auerbach 

 (Fig. 120A), with groups of ganglion cells in the 

 nodes ; this plexus lies between the longitudinal and 

 circular muscular coat. Another plexus connected 

 with the former lies in the submucous tissue ; this 

 is the plexus of Meissner, with ganglia. In both
