What is the primary function of the digestive system?
To break down and absorb nutrients, salts, and water, as well as to eliminate some wastes.
What is digestion?
Digestion is the process by which large complex molecules in food are broken down into smaller molecules that can be used by the body.
What is the digestive system?
A collection of organs that break down food into energy that can be used in cells.
What are sphincters?
Sphincters are rings of muscle which separate one section of the body from another.
What happens in the process of digestion (interactions?)
Digestion takes place through the interaction of enzymes, stomach acid, hormones, bile from the liver, and a network of nerves and muscles.
What happens after digestion is complete?
Nutrients are absorbed by the body and transported by the circulatory and lymphatic systems to all the cells. Undigested materials are then eliminated...

Digestion takes place through the interaction of enzymes, stomach acid, hormones, bile from the liver, and a network of nerves and muscles.
What happens after digestion is complete?
Nutrients are absorbed by the body and transported by the circulatory and lymphatic systems to all the cells. Undigested materials are then eliminated as liquids and solid wastes.
What are the two types of digestion that occurs in your mouth?
Mechanical and chemical digestion.
What is mechanical digestion in the mouth? What organs perform mechanical digestion? What happens to the food?
Chewing/mastication. Teeth, tongue, lips. The food is turned into a bolus.
What is chemical digestion in the mouth? (What does it involve?)
Chemical digestion in the mouth involves the action of enzymes. Salivary glands moisten the food and contains amylase, which breaks down starches into sugars. The tongue then moves the food to the esophagus.
What process keeps the food moving down the esophagus?
Peristalsis.
What is peristalsis?
Peristalsis is the contraction of smooth muscles to help push food down the esophagus.
What is the stomach?
A muscular sac that can expand to nearly twice its original size, and hold up to 2 L of food.
Which macromolecule(s) is/are digested in the stomach and small intestine? Which macromolecule(s) is/are digested only in the small intestine?
Proteins. Fats/Sugars.
What is the function of salivary amylase? Where is it located?
It breaks down complex starch molecules into sugars. Mouth.
What is the function of pepsin? Where is it located?
Pepsin is located in the stomach, and it breaks down proteins.
What is the function of maltase, lactase, and sucrase? Where are they located?
They break sugars into simpler molecules, and are located in the small intestine.
What is the function of peptidase? Where is it located?
Peptidase breaks down proteins into amino acids, and is located in the small intestine.
What is the function of trypsin? Where is it located?
Trypsin helps break down proteins. It is located in the small intestine and pancreas.
What is the function of amylase? Where is it located?
Amylase continues the breakdown of starches, and is located in the small intestine and pancreas.
What is the function of lipase? Where is it located?
Lipase helps break down fats, and is located in the small intestine and pancreas.
