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
humans digestion tube mouth to anus
extends from called alimentary canal
A muscular opening at the end of the rectum through
anus
which waste material is eliminated from the body
, 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
