Which type of digestion involves the physical breakdown of food into smaller pieces?
Mechanical Digestion
Chemical Digestion
What is the substance found in the stomach that allows for chemical digestion to take place?
Gastric Juices
Saliva

Insulin
Movement of food via involuntary muscle contractions is known as...
Peristalsis
Excretion
Squeezing
Transpiration
The enzyme found in saliva and the small intestine that breaks down carbohydrates
Amylase

Amylase
Protease
Lipase
The enzyme secreted by the pancreas that breaks down proteins
Amylase
Protease
Lipase
Pancrease
The gallbladder is most closely associated in it's function and position with the
esophagus
liver
pancreas
stomach
The function of the large intestine is to
digest protein
create bile
absorb water
produce gastric juices
This structure functions to increase the surface area of the small intestine
Lumen
Villi/Microvilli
Mucosa
Submucosa
Where is protein digested?
small intestine
large intestine
stomach
liver
Which is NOT a function of the Digestive System?
To rid the body of solid waste
Absorb nutrients for energy & growth
Break down nutrients from food
Absorb water
Store energy for cell respiration
Where does most assimilation take place?
In the small intestine
In the large intestine
In the cells
In the mouth
(b) = epithelial cells
(b) = goblet cells
(b) = mucosa
(b) = lacteal
(c) = circular muscles
(c) = epithelial cells
(c) = capillaries
(c) = goblet cells
A = epithelial layer; B = mucosa
C = circular muscle; D = longitudinal muscle
A = mucosa; B = epithelial layer
C = longitudinal muscle; D = circular muscle
A = epithelial layer ; B = villus
C = mucosa; D = longitudinal muscle
A = mucosa ; B = goblet cells
C = longitudinal muscle; D = plasma membrane
Lacteal carries....
monosaccharides to the liver
triglycerides to the lymphatic system
amino acids to the bloodstream
all of the above
The pancreas secretes...... (3)
amylase
endopeptidases
lipases
bile
lactase
What is true about gastric juices? (3)
It is highly acidic
It is highly alkaline
It contains proteases
It kills bacteria
It breaks proteins into amino acids
The main function of the large intestine is.....
to absorb nutrients from chyme
to absorb water from the remaining food
to masticate the chyme further
to add enzymes such as endopeptidases and amylase to the chyme
What substance emulsifies fats?
lipase
bile
pepsin
amylase
Which are true about epithelial cells in the small intestine? (3)
They are a single layer thick
They can contain immobilized/embedded enzymes
They are packed with mitochondria
They excrete bile
They are immune to proteases
Which is true about the digestion of proteins? (2)
They are broken down into polypeptides in the stomach by pepsin
They are broken down into amino acids in the small intestine by endopeptidase
They are broken down into glycerol in the small intestine by lipase
Once the amino acids diffuse into the epithelial cells they reform into a polypeptide
They are absorbed into the lacteal and distributed by the lymphatic system
Which are true about bile? (3)
It lubricates the movement of food along the intestines
It contains enzymes that break down proteins
It is made in the liver
It emulsifies fats
Finger-like projections in the small intestine that serve to increase surface area for better absorption.....
flagellum
villi
cillia
epithelia
What is the product of digestion by amylase?
glucose
maltose
fructose
sucrose
Which layer of the gut is responsible for peristalsis?
Smooth muscles
Mucosa
Submucosa
Serosa
Which layer of the alimentary canal has exocrine glands that release digestive enzymes and mucus?
mucosa
submucosa
muscular layer
serosa
Which layers of the alimentary canal are made of connective tissue?
mucosa
submucosa
muscular layer
serosa
