ANSWERS 2025-2026
mechanical digestion
Part of digestion that uses movement and muscles to break down
food into smaller pieces
digestion
breaking down nutrients into small, soluble molecules that can be
absorbed into the blood
chemical digestion
the digestion process in which enzymes are used to break foods
into their smaller chemical buiding blocks
occurs via hydrolysis
,hydrolysis
A chemical process that lyses, or splits, molecules by the addition
of water; an essential process in digestion.
enzymes
molecules, usually proteins or nucleic acids, that act as catalysts
in biochemical reactions
used in chemical reactions
humans digestion tube extends from
mouth to anus
called alimentary canal
anus
A muscular opening at the end of the rectum through which waste
material is eliminated from the body
, alimentary canal
Also known as the gastrointestinal (GI) tract of the digestive tract,
the alimentary canal is the long muscular "tube" that includes the
mouth esophagus, somatch, small intesitne, and large intestine.
carries out stages of digestive process (mechanical and chemical
digestion and absorb ion)
accessory organs
In the GI tract, organs that play a role in digestion but not directly
part of the alimentary canal.
These include the liver, the gallbladder, the pancreas
what takes place in the mouth?
mechanical digestion
saliva is released from salivary glands to breakdown carbs
