Label Structures of the Digestive System - Free Printable

Let's solve this Digestive System Worksheet by labeling the structures correctly based on the diagram and the provided word bank.

---

🔍 Step-by-step Solution:

We are given a diagram of the human digestive system with blank labels pointing to various organs. Below is a list of terms to choose from:

Word Bank:
- liver
- esophagus
- ascending colon
- duodenum
- rectum
- pancreas
- appendix
- transverse colon
- jejunum
- stomach
- gallbladder
- cecum
- descending colon
- ileum
- anus

Now, let’s identify each structure in the diagram from top to bottom and left to right.

---

#### 1. Top-left (above liver):
- The tube coming down from the mouth → esophagus

#### 2. Large organ on the upper right (brownish):
- This is the liver

#### 3. Small green sac beneath the liver:
- This is the gallbladder

#### 4. Curved organ below the liver, receiving food:
- This is the stomach

#### 5. Long green tube extending from stomach (curved part):
- First section after stomach → duodenum
- Then continues into jejunum
- Then ileum (last part of small intestine)

#### 6. Green coiled tube leading to large intestine:
- The ileum connects to the cecum, which is the beginning of the large intestine.

#### 7. C-shaped structure at the start of the large intestine:
- cecum

#### 8. Small pouch attached to cecum:
- appendix

#### 9. Horizontal segment of large intestine:
- transverse colon

#### 10. Descending vertical segment on the left:
- descending colon

#### 11. Ascending vertical segment on the right:
- ascending colon

#### 12. Final straight section before exit:
- rectum

#### 13. End point (exit):
- anus

#### 14. Pancreas:
- Located behind the stomach, connecting to the duodenum → pancreas

✔ Final Labeling (from top to bottom, left to right):

Let’s go through the lines one by one:

1. Esophagus – top tube from mouth
2. Liver – large organ above stomach
3. Gallbladder – small green sac under liver
4. Stomach – J-shaped organ below liver
5. Duodenum – first part of small intestine
6. Jejunum – middle part of small intestine
7. Ileum – last part of small intestine
8. Cecum – where small intestine meets large intestine
9. Appendix – small pouch off cecum
10. Transverse colon – horizontal part of large intestine
11. Descending colon – left side vertical part
12. Ascending colon – right side vertical part
13. Rectum – final straight portion
14. Anus – end opening
15. Pancreas – behind stomach, near duodenum

> ⚠️ Note: The pancreas might be labeled separately near the duodenum, even if not directly pointed to.
