Based on a test already found in the Library (12th Gr Digestive System), this quiz has been modified to suit the South African curriculum, with additional questions added.

Which sequence shows the pathway that food takes in the digestive system?

stomach, esophagus, small intestine, large intestine

stomach, esophagus, large intestine, small intestine

esophagus, stomach, small intestine, large intestine

esophagus, stomach, large intestine, small intestine

The digestion process begins in which of the following?

stomach

small intestine

large intestine

mouth

The pyloric sphincter is between the

Small Intestine and Large Intestine

Esophagus and Stomach

Stomach and duodenum

Pharynx and Esophagus

Which best describes the role of the esophagus in digestion?

It releases acid and mixes the food.

It aids in absorption of nutrients from food.

It carried food from the mouth to the stomach.

It carries food from the stomach to the intestines.

Bile is produced by the _, and stored in the __.

gallbladder, gallbladder

gallbladder, small intestine

liver, gallbladder

gallbladder, liver

The appendix is attached to the

ileum

cecum

colon

anal canal

Which of the following are components of the large intestine? (Select all that apply.)

What does the stomach do for the body?

It breaks food down.

It absorbs food.

None of the above

It assimilates food.

Which part of the digestive system absorbs most of the nutrients for the body to use?

3

What is the primary function of the large intestine?

to remove water from undigested waste

to beak down complex carbohydrates

to absorb nutrients

to digest proteins

The digestive system of most birds include a strucure called the gizzard. The gizzard crushes and grinds food, often with the help of smaller stones that the bird has swallowed.
Which of the following structures in the human digestive system has a function most similar to that of a bird's gizzard.

esophagus

small intestine

large intestine

teeth

Jorge is studying the digestive system. He found research indicating that more bacteria live in the large intestine that there are cells in the human body.

Based upon this research, which of these can Jorge logically conclude?

Bacteria are produced by the human body.

The large intestine is diseased.

The large intestine is made of bacteria.

Bacteria are necessary for digestion to occur.

Scientists are researching the effects of a drug used to treat acid reflux on digestion of food in the stomach. Pepsin is an enzyme found in the stomach that is active in digesting proteins.

If the drug being researched dramatically decreases the acidity in the stomach, which of the following is expected to occur?

Pepsin will be less active, causing a decrease in the digestion of proteins in the stomach.

The higher pH will stimulate pepsin  activity and decreased the amount

The lower pH will cause the denaturing of pepsin and result in digestion of fewer proteins in the stomach.

Production of pepsin will increase, resulting in more proteins being digested in the stomach.

The structure of the digestive tube in the grasshopper and earthworm consists of many folds. The folds affect the efficiency of food absorption by which of the following functions?

increasing surface area

reducing transpiration

reducing storage of sugars

increasing hormone secretion

What is peristalsis? What is its role in human digestion?

The diagram above shows the relationship between villi and microvilli. Label the more detailed diagram of the microstructure of a villus.

Match the functions on the left to the correct organs on the right (drag and drop).

Mixing food with saliva
Secretes basic solution to neutralise stomach acid
Mechanical digestion
Contains papillae (sense organ)
Secretes digestive juices for digestion in the small intestine
Secrete neutral to slightly acidic fluid to prevent bacterial growth
Forms bolus
Secrete fluid to assist in mechanical digestion
Secretes hormones to regulate sugar levels in the blood
Produce enzymes that begin the starch digestion

Tongue
Salivary glands
Pancreas
