Villi are projections of the intestinal lining that increase absorptive surface area.
572
Which digestive process is similar to soap emulsifying greasy dirt?
RRB Group-D
17/08/2022 / Shift II
2022
✓ Answer:ABile salts splitting large fat globules into smaller droplets
Bile salts emulsify fat into small droplets, increasing the surface area for lipase action.
573
Where are villi found in the body?
RRB NTPC (Stage-I)

2021
✓ Answer:ASmall intestine
The small intestine contains villi specialized for nutrient absorption.
574
Match the labelled organs in the source diagram: a = oesophagus, b = large intestine, c = small intestine, d = liver. Functions: i. Villi absorb water from food; ii. Length depends on the food an organism eats; iii. Helps emulsify fats; iv. No digestion. Select the matching option.
RRB Group-D
30/08/2022 / Shift I
2022
✓ Answer:Da-iv, b-i, c-ii, d-iii
Source key: D. The source statement i is flawed: the large intestine absorbs water but does not have villi. Villi occur in the small intestine. The organ labels are transcribed from the diagram, and the original matching choices are retained.
575
What are the finger-like projections that increase the small intestine's area for absorption called?
RRB Group-D
13/09/2022 / Shift II
2022
✓ Answer:DVilli
Villi enlarge the intestinal surface available for absorption.
576
What is the site of complete digestion of carbohydrates, proteins and fats?
RRB Group-D
17/09/2022 / Shift III
2022
✓ Answer:BSmall intestine
Pancreatic and intestinal enzymes complete digestion of these nutrients in the small intestine.
577
According to the source, enzymes for the final conversion of proteins into amino acids, carbohydrates into glucose, and fats into fatty acids and glycerol are present in:
RRB Group-D
26/08/2022 / Shift I
2022
✓ Answer:BIntestinal juice
Source key: B. Intestinal enzymes complete peptide and carbohydrate digestion. This school-level description simplifies fat digestion, which depends mainly on pancreatic lipase in the small intestine.
578
Lactose intolerance is:
RRB NTPC (Stage-I)
15/02/2021 / Shift II
2021
✓ Answer:DAn inability to adequately break down the sugar found in dairy products
Insufficient lactase activity impairs digestion of lactose, the principal sugar in milk.
579
Which part of the alimentary canal carries out complete digestion of carbohydrates, proteins and fats?
RRB Group-D
09/09/2022 / Shift I
2022
✓ Answer:ASmall intestine
Digestion is completed mainly in the small intestine.
580
Which features enable intestinal villi to absorb digested food? (i) Finger-like shape and very thin walls. (ii) Large surface area. (iii) Small pores for food to pass through. (iv) Rich blood-capillary supply.
RRB Group-D
26/08/2022 / Shift III
2022
✓ Answer:A(i), (ii) and (iv)
Villi provide a large, thin absorptive surface with a rich blood supply. Nutrients cross the epithelial lining rather than passing through simple pores.
