Part of digestion that uses movement and muscles to
mechanical digestion
break down food into smaller pieces
breaking down nutrients into small, soluble molecules
digestion
that can be absorbed into the blood
the digestion process in which enzymes are used to
break foods into their smaller chemical buiding blocks
chemical digestion
occurs via hydrolysis
A chemical process that lyses, or splits, molecules by
hydrolysis the addition of water; an essential process in
digestion.
molecules, usually proteins or nucleic acids, that act
as catalysts in biochemical reactions
enzymes
used in chemical reactions

Also known as the gastrointestinal (GI) tract of the
digestive tract, the alimentary canal is the long
muscular "tube" that includes the mouth esophagus,
alimentary canal somatch, small intesitne, and large intestine.
carries out stages of digestive process (mechanical
and chemical digestion and absorb ion)
In the GI tract, organs that play a role in digestion but
accessory organs not directly part of the alimentary canal.
These include the liver, the gallbladder, the pancreas
mechanical digestion
what takes place in the
saliva is released from salivary glands to breakdown
mouth?
carbs
three pairs of exocrine glands in the mouth that
salivary glands
secrete saliva
saliva contain amylase
enzyme in saliva that breaks the chemical bonds in
amylase
starches
muscular tube at the end of the gastrovascular cavity,
or throat, that connects the mouth with the rest of the
pharynx
digestive tract and serves as a passageway for air and
food
muscular tube that moves food from the pharynx to
esophagus
the stomach
The flap of tissue that seals off the windpipe and
epiglottis
prevents food from entering.
peristalsis
what takes place in the
gastric juices help breakdown proteins
stomach?
chyme is created
involuntary waves of muscle contraction that keep
peristalsis food moving along in one direction through the
digestive system

chemically breaksdown proteins
gastric juice
acidic (pH of 2)
mucus protects stomach wall from acidity of gastric juices
protease Enzyme that breaks down proteins
a semiliquid mass of partially digested food that
chyme
passes from the stomach into the small intestine
digestive organ in which most chemical digestion
small intestine takes place
majority of digestion and absorption occur here!!
how long is the SI? 6 meters
circular muscle that controls the movement of chyme
pyloric sphincter
from the stomach to the small intestines
liver large organ just above the stomach that produces bile
gallbladder stores bile
a mixture of salts and phospholipids that aids in the
bile
breakdown of fat
located partially behind the stomach in the abdomen,
and it functions as both an endocrine and exocrine
pancreas gland.
It produces digestive enzymes as well as insulin and
glucagon
after absorption, products blood and lymph
of digestion goes to
Small fingerlike projections on the walls of the small
villi
intestines that increase surface area
colon
organ that removes water from the undigested
large intestine
materials that pass through it
waste moves via peristalsis
rectum stores waste until egestion
