The main function of the human
digestive system is to
1) rid the body of cellular waste materials
2) break down large molecules so they
can enter cells
3) break down glucose in order to release
energy
4) change amino acids into proteins and
carbohydrates
Food is ingested through the
1) salivary glands
2) small intestine
3) mouth
4) rectum
Mechanical digestion in the oral
cavity is primarily the result of
1) peristalsis
2) chewing food
3) absorption
4) egestion
Chemical digestion in the mouth is
the result of
1) enzymes
2) hydrochloric acid
3) bile
4) pancreatic juice
Food that is swallowed enters the
1) stomach
2) small intestine
3) esophagus
4) large intestine
The esophagus pushed food
down into the stomach by the
involuntary process of
1. digestion
2. peristalsis
3. absorption
4. excretion
Identify the type of digestion that
takes place in the stomach.
1) mechanical digestion
2) chemical digestion
3) both mechanical and chemical
digestion
How does mechanical digestion in
the stomach occur?
1) enzymes
2) hydrochloric acid
3) peristalsis
4) mucus
How does chemical digestion in the
stomach occur?
1) peristalsis
2) enzymes
3) mucus
4) ulcers
Which substances in the small
intestine of humans serve to
increase the surface area for
absorption?
1. intestinal glands
2. villi
3. pseudopodia
4. cilia
Identify how the stomach lining is
protected from hydrochloric acid.
1) peristalsis
2) mucus
3) enzymes
4) bacteria
Identify the type of digestion that
occurs in the small intestine.
1) mechanical digestion
2) chemical digestion
3) both mechanical and chemical
digestion
Which statement regarding the small
intestine is incorrect?
1. Villi on the lining of the small intestine
absorb nutrients into the blood.
2. Chemical digestion is completed in the
small intestine.
3. Mechanical digestion is completed in the
small intestine.
4. The small intestine is where most
digestion occurs.
Which structures in the small
intestine absorb nutrients into the
blood?
1. intestinal glands
2. villi
3. pseudopods
4. cilia
Which substances are released into the
small intestine of a human and aid in the
digestion of food?
1) bile, pancreatic juice, and intestinal juice
2) hydrochloric acid, pancreatic juice, and
intestinal juice
3) salivary amylase, intestinal juice, and
pancreatic juice
4) bile, hydrochloric acid, and salivary
amylase
