A STUDY OF BLOOD MANUFACTURE

the right side of the body, just beneath the diaphragm, and 

 partially covers the py- 

 loric end of the stomach. 

 It consists of several 

 lobes, and on its under 

 surface is a small, green- 

 ish brown sac called the 

 gall bladder. The deep 

 red color of the liver is 

 partly due to the fact 

 that one fourth of all 

 the blood of the body is 

 found within its tissues. 

 Functions of the Liver. 

 The liver performs 

 three important func- 

 tions. In the first place, 

 it secretes a golden 

 brown liquid called the 

 bile, which is either 

 poured at once through 

 the bile duct into the 

 small intestine or is 

 stored in the gall blad- 

 der until needed. If 

 the bile duct becomes 

 stopped up, the bile is 

 absorbed into the blood 

 and gives to the tissues 

 the yellow tint that is 

 characteristic of jaun- 

 dice. The liver, in the 



second place, serves as a 

 great storehouse for the 

 carbohydrates when the 

 blood does not need them for immediate use.
