The digestive system of an organism is quite a complicated system and it is influenced by many factors and substances as well as by a large number of different chemical elements. Any changes, even the slightest ones may produce a significant influence on the work of the organism at large and digestive system in particular.
At this respect it is noteworthy the role that pancreatic juice play in the process of digestion. The reason is that pancreatic juice is the major source of lipases, or fat-digesting enzymes while bile emulsifies fat, thereby increasing the ability of lipases to digest fatty food. Moreover, bile is also necessary for absorption of the products of fat breakdown. In such a way pancreatic and bile juices are very important because without them little fat breakdown and absorption can occur.
Consequently, the natural result of the absence of pancreatic and bile juice is fatty stool because fat consumed by a human being cannot be normally absorbed in the organism as it happens when there is sufficient amount of pancreatic and bile juice. The knowledge concerning the role of pancreatic and bile juice is very important, especially for a RN because it provides him/her with information about a proper nutrition and needs of human body making possible better functioning of digestive system due to a carefully arranged diet.
