Let's solve this step-by-step by matching each organ in
Column A with the correct description from
Column B, based on the diagram and the information provided.

Step 1: Understand the Diagram
From the image, we can gather the following key functions:
-
Mouth: Holds, tears, chews food; salivary glands secrete juices.
-
Teeth: Hold, tear, chew food (break and grind).
-
Tongue: Moves food into a ball for swallowing.
-
Salivary glands: Secrete digestive juices into the mouth.
-
Esophagus: Passageway between mouth and stomach.
-
Stomach: Receives food, churns it, adds gastric juices.
-
Liver: Produces bile.
-
Gall bladder: Stores bile until needed.
-
Pancreas: Produces digestive juices.
-
Small intestine: Absorbs usable food substances via blood vessels; digestion is complete here.
-
Large intestine: Stores unused solid substances after water is removed.
-
Rectum: Holds solid waste and controls its release.
-
Villi: Tiny finger-like projections in the small intestine that help absorb nutrients.

Now, let’s match each item in
Column A to the best statement in
Column B.

→
Answer: C
5.
teeth
→ "Breaks, grinds food into pieces"
→
Answer: G
6.
small intestine
→ "Absorbs food, sends it through body"
→
Answer: H
7.
salivary glands
→ "Produce juices in the mouth"
→
Answer: B
8.
gall bladder

✔ Final Answers:
1.
D — mouth
2.
E — large intestine
3.
A — liver
4.
C — stomach
5.
G — teeth
6.
H — small intestine
7.
B — salivary glands
8.
I — gall bladder
9.
F — villi

📝 Explanation Summary:
- The
mouth starts digestion mechanically (chewing) and chemically (saliva), so
D fits.
- The
large intestine absorbs water and stores waste, so
E.
- The
liver makes bile (a digestive fluid), so
A.
- The
stomach churns food and adds gastric juices, so
C.
-
Teeth break down food physically, so
G.
- The
small intestine absorbs nutrients into the bloodstream, so
H.
-
Salivary glands produce saliva (digestive juices), so
B.
- The
gall bladder stores bile until needed, so
I.
-
Villi are tiny projections in the small intestine that increase surface area for absorption, so
F.
✔ All matches are consistent with the diagram and biological knowledge.
