Quiz Question 3
To clarify the role of bile in the digestion of lipids/fats ....
When food enters the stomach, the process of breaking it down to its component parts begins. The broken
down food is called chyme and is a watery liquid that is then emptied into the small intestine - the
duodenum. When the chyme enters the duodenum, bile is secreted into the duodenum and its purpose is to
coat the lipid molecules to keep them in suspension within the watery chyme mixture. By doing this, the
fat digesting enzymes can work on the lipid molecules and break them down into the component parts.
IF you do not have bile, then the lipid molecules will all clump together - think of oil and vinegar salad
dressing that has been alllowed to set a while in the fridge ....... Anf of course, by sticking together, the
lipid molecules could not be truly digested and absorbed.
Hope this helps you understand the process and question 3. on the lesson quiz.
