DETAILED SYNTHESIS. 



Fig -233. THE SEROUS 



MEMBRANE OF THE STOMACH 



CAN BE TRACED up at 4, then 

 forward under the liver, L, 

 up over it to 3, where it 

 passes to the under surface 

 of the diaphragm, D , from 

 the front part of which it 

 extends down, forming the 

 inner sdrface of the walls of 

 the abdomen, and is there 

 called peritoneum. From 5, 

 the serous membrane of the 

 front part of the stomach 

 extends down, as seen, turns 

 up, passes to the under part 

 of C, colon, the surface of 

 which it forms, then ex- 

 tends to the duodenum, D, 

 turning down at 10 from 



* 



tend to I, small intestine. 

 the external coat of which it forms, and extends up back, adhering 

 throughout to 11, thus forming what is called a mesentery, in the midst 

 of which blood-vessels, lacteals, and nerves are found connecting with the 

 second stomach. Again, at 5, the serous membrane from the jack of the 

 stomach extends down to 6, adhering all the way to the layer from the 

 front of the stomach ; it turns up, dividing at C, the colon, to form its 

 front and upper surface, a part of its mesentery, at 7, a small portion of 

 D, binding down the pancreas P, and so on around to L, and down to S, 

 the starting-point. 



Second Stomach. 



1078. The food, having been dissolved, and its sev- 

 eral varieties set at liberty in the first stomach, THE 



PASTY MASS, CALLED CHYME, IS READY TO RECEIVE the 



influence of different fluids adapted to act upon each 

 variety and prepare it to pass into the Blood, while a 

 great extent of surface is necessary in order that every 

 particle of useful substance may be abstracted. 



Describe Fiz. 233. Are the contents of the abdomen attached to itsfront walls? 

 Do the contents in reality perfectly fill the walls ? 1078. What is ?
