BIO-319 QUIZ 2 STUDY GUIDE CH. 3,4,18
WITH COMPLETE SOLUTIONS
Define digestion - ANSWER-the process by which food is broken down into absorbable
units.
Name and describe the function of the organs of the digestive system - ANSWER-
Mouth
A body opening where an animal takes in food. Mechanical and Chemical digestion
start here.
Teeth
Hard structures in the mouth used for Mechanical Digestion: cutting, biting, and chewing
food.
Saliva
The liquid produced in the mouth that aids Chemical Digestion.
Esophagus
The tube connecting the mouth to the stomach. Food is moved through a process called
Peristalsis.
Stomach
The organ where food is reduced to liquid Chyme by Chemical (acid) and Mechanical
(muscle activity) digestion.
Small Intestine
The part of the digestive system between the stomach and large intestine that absorbs
nutrients from digested food using the Villi.
Large Intestine
The part of the digestive system between the small intestine and the rectum where
water is removed from the solid waste. Also called the Colon.
Colon
, The large intestine where solid waste is dried and compacted in preparation for
elimination.
Digestive System
The system of organs and structures responsible for the digestion, absorption, and
elimination of food. The digestive system includes Teeth, Mouth, Esophagus, Stomach,
Small, Intestine, Large Intestine. It relies on support from other organs like the Liver,
Gall Bladder, and Pancreas.
Digestion
The process of breaking down food into nutrients that can be used by cells.
Liver
Produces Bile to help break down fats in the small intestines
Gall Bladder
Stores extra Bile produced by the liver
Pancreas
Produces Enzymes to help further break down carbohydrates, fats, and proteins in the
small intestines
List the name and functions of the accessory organs of the digestive system -
ANSWER-Mouth
-Teeth chew food
-Tongue positions and tastes food
Salivary glands
-saliva moistens food
-Bicarbonate maintains pH
-Amylase digests starch
-Lysozyme inhibits bacteria
Pharynx
-passageway for food and air
-participates in swallowing
Esophagus
-Moves food from pharynx to stomach
