WorksheetsPractice CFA - The Digestive System
Total questions: 10
Worksheet time: 5mins
How does mechanical digestion differ from chemical digestion?
Mechanical involves enzymes; chemical involves chewing
Mechanical changes food’s structure; chemical changes molecules
Mechanical occurs in the pancreas; chemical occurs in the liver
Mechanical uses acids; chemical uses physical motion
Why would removing the large intestine severely affect the body’s balance?
It helps digest all fats and proteins
It produces most of the body’s insulin
It absorbs water and forms solid waste
It neutralizes acids from the stomach
If the gallbladder fails to release bile, what process will be most directly affected?
Digestion of carbohydrates in the mouth
Breakdown of proteins in the stomach
Emulsification of fats in the intestine
Absorption of water in the colon
A person has difficulty swallowing food. Which part of the digestive system is most likely affected?
Pancreas due to enzyme shortage
Esophagus due to muscle function
Stomach due to acid production
Liver due to bile secretion
Which organ is responsible for nutrient absorption into the blood?
Esophagus through smooth muscle action
Stomach through chemical breakdown
Small intestine through villi structures
Large intestine through water removal
What is the main function of the digestive system?
To produce energy for cellular respiration
To circulate nutrients to all body systems
To regulate hormones in the bloodstream
To break down food for nutrient absorption
How does the stomach protect itself from its own acidic environment during digestion?
It produces a thick layer of mucus that coats its lining, preventing damage from stomach acid.
It releases enzymes that neutralize the acid before it can cause any harm to the stomach walls.
It continuously replaces its lining every few hours to avoid the effects of acid damage.
It reduces its acid production during food digestion to prevent any irritation.
Teeth chewing is an example of what type of digestion?
Mechanical digestion
Indigestion
Gastrointestinal digestion
Chemical digestion
What do you call the wave-like motion in your esophagus in the digestion process?
Pertalsis
Peristalsis
Peristals
Perstalation
Emma ate a meal that was high in fats. After digestion in the stomach, the chyme moves into the small intestine. What is most likely happening during this stage?
Bile from the liver is being released to emulsify fats for easier absorption.
The stomach is releasing more acid to further break down the food.
Enzymes in the large intestine are beginning to absorb water from the chyme.
The pancreas is filtering out toxins before the nutrients enter the bloodstream.
