Label the Diagram: The Human Digestive System | Worksheet ... - Free Printable

Let’s go step by step to label the human digestive system diagram using the word bank.

We’ll match each number on the diagram with the correct organ or part from the word bank:

Word Bank:
- salivary gland
- tongue
- teeth
- salivary glands (plural — but note: there are two places for “salivary glands” in the diagram, as noted)
- esophagus
- gallbladder
- pancreas
- large intestine
- appendix
- stomach
- liver
- small intestine
- rectum

Now, let’s identify each numbered line based on standard anatomy of the human digestive system:

1. Points to the mouth area → likely teeth (since it’s pointing at the front of the mouth where teeth are)
2. Also points to mouth area, slightly lower → likely tongue
3. Points to a gland near the jaw/cheek → salivary gland (one of them)
4. Points to another gland near the other side of the jaw → salivary glands (second location — note says there are two places)
5. Points to the tube going down from throat to stomach → esophagus
6. Points to the J-shaped organ after esophagus → stomach
7. Points to the coiled tubes below stomach → small intestine
8. Points to the upper right abdominal organ (large, dark shape) → liver
9. Points to the structure under the liver → gallbladder
10. Points to the organ behind the stomach → pancreas
11. Points to the wider tube surrounding small intestine → large intestine
12. Points to the very end of the large intestine before exit → rectum
13. Points to the tiny pouch attached to large intestine → appendix

Wait — let’s double-check numbering and positions carefully.

Looking again at typical diagrams:

Usually:
- 1 = teeth
- 2 = tongue
- 3 = salivary gland (parotid, near ear/jaw)
- 4 = salivary glands (submandibular/sublingual — under jaw/tongue) — so yes, two spots for salivary glands
- 5 = esophagus
- 6 = stomach
- 7 = small intestine
- 8 = liver
- 9 = gallbladder (under liver)
- 10 = pancreas (behind stomach)
- 11 = large intestine
- 12 = rectum
- 13 = appendix

But wait — in some diagrams, #13 might be pointing to the cecum or appendix. Since “appendix” is in the word bank and it’s a small pouch off the large intestine, that fits.

Also, note: The word bank has “salivary gland” (singular) and “salivary glands” (plural). The note says: “There are two places on the diagram where you will label salivary glands.” So we use “salivary gland” for one spot and “salivary glands” for the other? Or both get “salivary glands”? Actually, looking at the word bank, it lists both “salivary gland” and “salivary glands” — probably meaning one is singular label, one is plural. But anatomically, they’re all called salivary glands. However, since the instruction says “use the word bank”, we must pick exactly what’s listed.

So:

→ For #3: likely “salivary gland” (if it’s pointing to one specific gland)
→ For #4: “salivary glands” (if it’s pointing to multiple or the group)

But actually, in many school diagrams, #3 and #4 are both labeled “salivary glands” — but here the word bank gives both forms. Let’s assume:

#3 → salivary gland
#4 → salivary glands

(Alternatively, maybe #3 is tongue? Wait no — #2 is already tongue.)

Let me reassign based on common labeling:

Standard labeling order for such diagrams:

1. Teeth
2. Tongue
3. Salivary gland (e.g., parotid)
4. Salivary glands (e.g., submandibular — under jaw)
5. Esophagus
6. Stomach
7. Small intestine
8. Liver
9. Gallbladder
10. Pancreas
11. Large intestine
12. Rectum
13. Appendix

Yes, this matches.

Final check: All words used?

Used:
- teeth (#1)
- tongue (#2)
- salivary gland (#3)
- salivary glands (#4)
- esophagus (#5)
- stomach (#6)
- small intestine (#7)
- liver (#8)
- gallbladder (#9)
- pancreas (#10)
- large intestine (#11)
- rectum (#12)
- appendix (#13)

All 13 items matched. Word bank had 13 terms? Let’s count word bank:

salivary gland
tongue
teeth
salivary glands
esophagus
gallbladder
pancreas
large intestine
appendix
stomach
liver
small intestine
rectum

That’s 13 terms. Perfect.
