1 / -0

You have just put a piece of bread in your mouth. The enzyme that will be secreted in the saliva to begin its digestion is:

A
Pepsin

B
Gastrin

C
Trypsin

D
Amylase

Solution

Carbohydrate digestion begins in the mouth by the action of salivary amylase. Bread is a source of carbohydrates. Hence, its digestion begins in the mouth.

A
The tongue aids in the digestion of the food.

B
The saliva changes some of the starch in the food to sugar.

C
The tongue keeps the food in place in the mouth while the food is being chewed.

D
The digestive juices can react more easily with the food when chewed.

Solution

Tongue does not help in the process of digestion. It helps in mixing the food with the saliva. The tongue also keeps the food in place in the mouth while the food is being chewed.
Question 3
1 / -0

Read carefully the terms given below. Which of the following is the correct combination of organs that do not carry out any digestive functions?

A
Oesophagus, Large intestine, Rectum

B
Buccal cavity, Oesophagus, Rectum

C
Buccal cavity, Oesophagus, Large intestine

D
Small intestine, Large intestine, Rectum

Solution

Oesophagus, large intestine and rectum do not carry out any digestive functions. Digestion of carbohydrates starts in the buccal cavity. Carbohydrates, fats and proteins are digested in the small intestine.
Question 4
1 / -0

Which of the following is/are NOT a component of gastric juice?

A
Mucus

B
HCl

C
Bile

D
Enzymes

Solution

Bile is not a constituent of gastric juice. Bile is produced by the liver, and stored and concentrated in the gall bladder. Bile helps in the emulsification of fats.
Question 5
1 / -0

Which of the following is responsible for storing bile?

A
Liver

B
Gall bladder

C
Pancreas

D
Stomach

Solution

Bile is produced by the liver, and stored and concentrated in the gall bladder.
Question 6
1 / -0

The digestive system processes food into usable and unusable materials. The usable materials are sent to the body's cells as food. What happens to unusable materials?

A
They go into the pancreas to await disposal.

B
They go into the right ventricle to await disposal.

C
They go into the large intestine to await disposal.

D
They go into the small intestine to await disposal.

Solution

The undigested food material that is not absorbed in the small intestine passes into the large intestine. Here, water is absorbed and the remaining waste material is stored as faeces before being removed by defecation.
Question 7
1 / -0

Which of the following organs stores the faecal matter in the body?

A
Anus

B
Large intestine

C
Rectum

D
Appendix

Solution

The rectum is the final segment of the large intestine that connects the colon to the anus. It stores the faecal matter produced in the colon until the body is ready to eliminate the waste through the process of defecation.
Question 8
1 / -0

Cellulose-rich food substances are good source of roughage in human beings because

A
human beings do not have cellulose-digesting enzymes

B
cellulose gets absorbed in the human blood and converts into fibres

C
the cellulose-digesting bacteria convert cellulose into fibres

D
cellulose breaks down into smaller components which are egested as roughage

Solution

Cellulose and other types of fibre are components of plants that the human body cannot break down and absorb. When eaten, cellulose passes through the gastrointestinal tract relatively intact.
