Questions and Correct
Answers | New Update
Digestive System - ANSWER ✔✔organ system that processes food,
extracts nutrients, and eliminates residue
How does the digestive tract work as an assembly line - ANSWER
✔✔Breaks down nutrients into forms that can be used by the body &
absorbs them so they can be distributed to the tissues
What are the five stages of digestion - ANSWER ✔✔Ingestion,
Digestion, Absorption, Compaction, Defecation
,Ingestion - ANSWER ✔✔Selective intake of food
Digestion - ANSWER ✔✔Mechanical and chemical breakdown of
food into a form usable by the body
Absorption - ANSWER ✔✔Uptake of nutrient molecules into the
epithelial cells of the digestive tract and then into the blood and lymph
Compaction - ANSWER ✔✔Absorbing water and consolidating the
indigestible residue into feces
Defecation - ANSWER ✔✔Elimination of feces
Mechanical digestion - ANSWER ✔✔The physical breakdown of food
into smaller particles; cutting and grinding action of teeth, churning
action of stomach and small intestine, exposes more food surface to
digestive enzymes
Chemical Digestion - ANSWER ✔✔A series of hydrolysis reactions
that breaks dietary macromolecules into monomers (residuals), carried
out by digestive enzymes produced by salivary glands, stomach,

, What are the six function of the digestive tract - ANSWER ✔✔Motility,
secretion, digestion, absorption, storage and elimination, immune barrier
Motility - ANSWER ✔✔Ingestion, mastication, deglutition, peristalsis,

Absorption - ANSWER ✔✔Passing broken-down food into blood or
lymph
Storage and elimination - ANSWER ✔✔temporary storage and
elimination of undigested food
Immune barrier - ANSWER ✔✔Epithelium of small intestine are lined
with tight junctions that prevents swallowed pathogens from entering
body
Mastication - ANSWER ✔✔Chewing
Deglutination - ANSWER ✔✔Swallowing
Peristalsis - ANSWER ✔✔One-way movement through the tract
Segmentation - ANSWER ✔✔Churning/mixing
