Question

What does bile do for the digestive system?
It helps breakdown protein
It is not part of the digestive system
It is part of the blood

Answer 1

Bile plays a crucial role in the digestive system, primarily in the digestion and absorption of fats. It does this by emulsifying dietary fats, which increases the surface area for digestive enzymes to act upon, making it easier for the body to absorb fat-soluble vitamins and nutrients. Bile is produced by the liver and stored in the gallbladder, ultimately released into the small intestine during digestion.

So, from the options you provided, none are accurate descriptors of bile's function. Specifically, bile does not help break down proteins, it is indeed part of the digestive system, and it is not part of the blood.
