The large intestine stores bile.
The large intestine has a larger diameter than the small intestine.
The large intestine stores, compacts, and eliminates indigestible material.
What is the function of the small intestine?
Contains villi that pass nutrients to the bloodstream.
Produces stomach acid
Stores bile for the liver
Breaks down toxins
Which of the following is NOT a function of the liver?

True or False: Mechanical digestion is the breaking, crushing, and mashing of food.
True
False
Chemical digestion...
Is the chewing, mashing and breaking of food.
Is the breaking down of large molecules into nutrients.
Is the storage of bile from the liver
Happens only in the small intestine
How does bile help digest fat?
By removing the water from fat
By storing and filtering blood
Mechanical digestion
Bile breaks large fat droplets into very small droplets.

The pancreas makes hormones that regulate blood sugar.
The pancreas stores bile.
The pancreas makes fluids that protect the small intestine from acid.
The pancreas breaks down fat molecules.
What is the role of the gallbladder in digestion?
The gallbladder makes bile.
It is the largest organ in the digestive system.
The gallbladder stores bile produced by the liver.
It stores nutrients.
What is the role of the pancreas in digestion? Choose all that apply.
Absorbs nutrients into the bloodstream.
Makes hormones that help with blood sugar regulation
Stores bile
Makes enzymes that break down sugar, starches, and fats.

What happens if one organ of the digestive system is not functioning properly?
We will not be able to digest food properly.
We will have no problems.
It will only affect my digestive system, but not other body systems.
Why do we need to break apart the food we eat?
So it can fit into our stomachs
So our bodies can use the nutrients from the food
So liquids can be separated from solids
So that our bodies' enzymes have something to do.
Hydrochloric acid is a caustic chemical that can burn your skin- and yet it exists in your stomach. How can this be?
Your small intestines absorb all the hydrochloric acid
The food in your stomach absorbs all the acid
Your stomach lining protects you against burns
The hydrochloric acid in your stomach is different from the hydrochloric acid you would find in a chemistry lab
What is the main function of villi?
They move food from the stomach to the small intestine
They absorb nutrients into the bloodstream
They absorb water from chyme
They move food from the small intestine to the large intestine
What might happen if your large intestine did not absorb water from chyme?
You couldn't digest food.
You wouldn't be able to go to the bathroom.
You would become dehydrated.
Solid waste would not be able to move throughout the digestive system
Enzymes in your saliva help break down food, this is an example of ...
Mechanical digestion
Chemical digestion
