362 DETAILED SYNTHESIS. 



canal the semi-fluid mass is pressed slowly over the deli- 

 cate surface, and each particle ultimately brought in con- 

 tact with it, and removed either into the lacteals or into 

 the capillaries. 



1110. THE RESIDUAL MASS, constituting but a small 

 part, is urged onward into the colon, from which it can- 

 not readily return on account of the valve-like arrange- 

 ment shown at 8, Fig. 239. Another portion excreted 

 by the glands and cells of the second stomach is also 

 passed on into the colon. 



Colon. 



1111. THE COLON is a larger canal than the second 

 stomach or small intestine. Its mucous coat is formed 

 into pouches by the contraction of its muscular bands, 

 and its surface is studded with punctures, the mouths 

 of tubular glands, in appearance like those of the second 

 stomach ; but their office seems to be different, it being to 

 eliminate from the Blood useless material, which forms the 

 chief part of the contents usually to be found in the colon. 



1112. THE LONGITUDINAL MUSCULAR FIBRES OF THE 



COLON are gathered into three bundles, shorter than the 

 mucous or serous coats, giving the colon a pouched ap- 

 pearance, and producing a condition by which the con- 

 tents of the colon may be detained. 



1113. THE LENGTH OF THE COLON is about five feet, 

 commencing within the right hip (Fig. 234), where it is 

 fastened down quite closely (Fig. 240). It then ascends 

 to the liver, turns across the abdomen to the left side, 

 down which it follows, curving over the inner surface of 

 the hip, and then becomes straight, or the rectum. 



1114. Inf. It MUST BE EVIDENT that tight clothing or bandages 

 just above the hips will tend to obstruct the passage of the contents of 

 the colon, both upward into the transverse, and from it downward into 

 the descending.
