The Digestive System of the Human Body

The process in which your body breaks down food into small nutrient molecules is called:

Where does peristolsis take place?

A muscular tube that connects the mouth to the stomach.

The process that involves involuntary contractions through the esophagus is called:

This organ stores bile.

Most mechanical digestion, and some chemical digestion takes place in the:

The flap of tissue that covers the windpipe is called the

Where does the MOST chemical digestion take place?

Structures inside the small intestine, that create a larger surface area for absorption of food

Where final absorption of only water, and waste materials are compressed, to be eliminated.

The last section of the digestive system where water is absorbed, and waste eliminated.

What chemical in the mouth contains an enzyme to begin chemical digestion?

The mouth releases this fluid when it waters to help in mechanical and chemical digestion.

A substance produced by the liver that breaks down fat particles.

The part of the digestive system in which most chemical digestion takes place.

What are the structures that line the small intestines:

Water is a nutrient in which chemical digestion takes place in.

What part of the digestive system secretes saliva?

This organ makes bile.

What organ releases enzymes to break down starches, proteins, and fats in the small intestine?

What type of digestion takes place in the Mouth?

Water only is absorbed in the

A flap of tissue that seals off the windpipe and prevents food from entering.

The energy your body needs comes from:

The structure(s) that enable(s) the small intestines to absorb lots of nutrients?

The mouth and stomach are lined with a slippery substance called:

One of the jobs of the __________________ intestines is to prepare waste for elimination.

This organ stores bile

Chemical digestion is helped along by a strong acid in the stomach called:

Pepsin works best in the presence of

Involuntary waves of muscle contractions that move food along the digestive system.

A slippery substance that is produced by the body.

When nutrient molecules pass through the wall of the digestive system into the blood.

A J-shaped muscular pouch, in which mechanical and chemical digestion occur.

When comparing the size of the small and large intestines, measurement is based on:

What takes place in the large intestines?

What organ produces bile?

A muscular opening at the end of the digestive system where waste is eliminated from the body

A protein that speeds up chemical reactions

The type of involuntary muscle that moves through the digestive tract is called:

Digestion begins in the

An organ that produces an enzyme that breaks down starches, proteins, and fats.
