To solve this worksheet, we need to match the labels to the correct parts of the digestive system diagram. We will go through the diagram generally from top to bottom and left to right.
Step 1: The Upper Digestive Tract (Top Section)
1.
Esophagus: The long tube at the very top center that carries food down is the
esophagus.
2.
Liver: The large, reddish-brown organ on the left side of the image (which is the right side of the body) is the
liver.
3.
Gallbladder: The small green sac tucked underneath the liver is the
gallbladder.
4.
Stomach: The J-shaped organ on the right side of the image (left side of the body), next to the liver, is the
stomach.
5.
Pancreas: The yellowish, leaf-shaped gland located behind/below the stomach is the
pancreas.
Step 2: The Small Intestine (Middle Section)
The small intestine has three parts. Let's trace the path of food leaving the stomach.
6.
Duodenum: The very first short section of the small intestine, shaped like a "C" around the pancreas, is the
duodenum.
7.
Jejunum: The middle section of the coiled small intestine is the
jejunum.
8.
Ileum: The final section of the small intestine that connects to the large intestine is the
ileum.
Step 3: The Large Intestine (Outer Frame)
Now we follow the large intestine, which frames the small intestine.
9.
Cecum: The pouch-like beginning of the large intestine where the ileum connects is the
cecum.
10.
Appendix: The small, finger-like projection hanging off the cecum is the
appendix.
11.
Ascending Colon: The part of the colon that goes *up* the right side of the body (left side of the image) is the
ascending colon.
12.
Transverse Colon: The part that goes *across* the top is the
transverse colon.
13.
Descending Colon: The part that goes *down* the left side of the body (right side of the image) is the
descending colon.
Step 4: The Lower Digestive Tract (Bottom Section)
14.
Rectum: The straight section at the very end of the colon before the exit is the
rectum.
15.
Anus: The final opening at the bottom is the
anus.

Final Answer:
Here are the correct labels for the structures, listed generally from top to bottom based on their position in the diagram:
Top Section:
* Top center tube:
esophagus
* Large organ on the left:
liver
* Small green sac under the liver:
gallbladder
* J-shaped organ on the right:
stomach
* Gland below the stomach:
pancreas
Middle Section (Small Intestine):
* First loop after stomach:
duodenum
* Middle coils:
jejunum
* Last loops connecting to large intestine:
ileum
Large Intestine & Lower Section:
* Pouch at start of large intestine:
cecum
* Small tag hanging off cecum:
appendix
* Upward side of large intestine:
ascending colon
* Across the top:
transverse colon
* Downward side of large intestine:
descending colon
* End storage area:
rectum
* Final opening:
anus
