Part of digestion that uses movement and muscles to break down
mechanical digestion
food into smaller pieces
breaking down nutrients into small, soluble molecules that can
digestion
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 the
hydrolysis
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 extends mouth to anus
from called alimentary canal
A muscular opening at the end of the rectum through which
anus
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, somatch, small intesitne, and large intestine.
alimentary canal
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 not
accessory organs directly part of the alimentary canal.
These include the liver, the gallbladder, the pancreas
mechanical digestion
what takes place in the mouth?
saliva is released from salivary glands to breakdown carbs
, salivary glands three pairs of exocrine glands in the mouth that secrete saliva
saliva contain amylase
amylase enzyme in saliva that breaks the chemical bonds in starches
muscular tube at the end of the gastrovascular cavity, or throat,
pharynx that connects the mouth with the rest of the digestive tract and
serves as a passageway for air and food
esophagus muscular tube that moves food from the pharynx to the stomach
The flap of tissue that seals off the windpipe and prevents food
epiglottis
from entering.
peristalsis
what takes place in the
gastric juices help breakdown proteins
stomach?
chyme is created
involuntary waves of muscle contraction that keep food moving
peristalsis
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 passes from the
chyme
stomach into the small intestine
digestive organ in which most chemical digestion takes place
small intestine
majority of digestion and absorption occur here!!
how long is the SI? 6 meters
circular muscle that controls the movement of chyme from the
pyloric sphincter
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 breakdown
bile
of fat
located partially behind the stomach in the abdomen, and it
pancreas functions as both an endocrine and exocrine gland.
It produces digestive enzymes as well as insulin and glucagon
after absorption, products of blood and lymph
digestion goes to
Small fingerlike projections on the walls of the small intestines
villi
that increase surface area
colon
organ that removes water from the undigested materials that
large intestine
pass through it
waste moves via peristalsis
rectum stores waste until egestion
egestion Removal of undigested waste
carbohydrate (enzymes, end 1. amylase, sucrase, maltase
products and important 2. glucose
locations) 3. starts in mouth, completed in SI
