lubricates the food, making it slick. It also protects the stomach from the strong
digestive juices.
What would happen if the stomach did not have mucous or produced more acid

What does the liver do?-correct-answer-It produces a greenish fluid called bile,
which is stored in the gallbladder. The acid from the stomach makes large fat
particles float to the top of the liquid. Bile physicallly breaks these fat particles
into smaller pieces.
What does the pancreas do?-correct-answer-It helps make insulin, a hormone
that allows glucose to pass from the bloodstream into your body's cells.
What is insulin?-correct-answer-A hormone that allows glucose to pass from the
bloodstream into your body's cells.
The walls of your small intestine are not smooth. They have many ridges and folds.
These ridges and folds are covered with tiny, fingerlike projections called what?-
correct-answer-Villi.
How is food absorbed?-correct-answer-The chyme is like a soup, and it is ready to
be absorbed through the cells on the surface of the villi. Molecules of nutrients
from your school lunch pass by diffusion, osmosis or active transport into the
blood vessels in the villi. Whatever is not absorbed is moved to the large intestine.
