Interactive worksheet for identifying parts of the digestive system.

Let me carefully examine the diagram and match each organ label to its correct position in the digestive system.

First, I'll identify the locations of the blank boxes and match them with the organ names provided.

The organs listed are:
- Liver
- Gall bladder
- Pancreas
- Mouth
- Anus
- Large Intestines
- Small Intestines
- Epiglottis
- Esophagus
- Stomach
- Salivary Glands
- Rectum

Now I'll locate each part on the diagram:

1. Top left blank (near mouth/throat area) → Salivary Glands (they're near the mouth)
2. Top right blank (near mouth/throat) → Mouth
3. Next blank below mouth (tube going down) → Esophagus
4. Blank pointing to the flap covering windpipe during swallowing → Epiglottis
5. Large organ on right side (shaded gray) → Liver
6. Small sac attached to liver → Gall bladder
7. Organ below stomach (long tube coiled up) → Small Intestines
8. Larger tube surrounding small intestines → Large Intestines
9. Organ above small intestines, J-shaped → Stomach
10. Gland behind stomach → Pancreas
11. Bottom end of large intestine → Rectum
12. Very end opening → Anus

Let me double-check by tracing the digestive path:
Mouth → Salivary Glands (near mouth) → Epiglottis (covers trachea) → Esophagus → Stomach → Pancreas (next to stomach) → Liver → Gall bladder (on liver) → Small Intestines → Large Intestines → Rectum → Anus

Now I'll assign each blank in order from top to bottom, left to right:

Top row blanks (left to right):
- Left: Salivary Glands
- Right: Mouth

Next row (left to right):
- Left: Epiglottis
- Right: Esophagus

Middle section (left side, top to bottom):
- First: Liver
- Second: Gall bladder
- Third: Stomach
- Fourth: Small Intestines
- Fifth: Large Intestines
- Sixth: Rectum

Middle section (right side, top to bottom):
- First: Pancreas
- Second: (already used most) — wait, let me count the blanks.

Actually, let me count the blank boxes precisely:
- Top: 2 blanks
- Below that: 2 blanks
- Middle left: 4 blanks
- Middle right: 3 blanks
- Bottom: 2 blanks

That's 13 blanks total, but we have 12 organ names. Let me recount the organ list: 12 items.

Looking more carefully at the diagram structure:
- The two top blanks point to areas near the mouth/throat
- Then two blanks pointing to throat/esophagus area
- Then on the left side of abdomen: 4 blanks
- On the right side of abdomen: 3 blanks
- At the bottom: 2 blanks

The standard digestive system labeling would be:
1. Salivary Glands (near mouth)
2. Mouth
3. Epiglottis (flap in throat)
4. Esophagus (tube down)
5. Liver (large gray organ on right)
6. Gall bladder (small sac under liver)
7. Stomach (J-shaped organ)
8. Pancreas (behind stomach)
9. Small Intestines (coiled tube)
10. Large Intestines (outer frame around small intestines)
11. Rectum (end of large intestine)
12. Anus (final opening)

Let me map the blanks in the order they appear in the diagram from top to bottom, left to right:

Top left blank → Salivary Glands
Top right blank → Mouth
Middle left blank (below salivary glands) → Epiglottis
Middle right blank (below mouth) → Esophagus
Left side, first abdominal blank → Liver
Left side, second abdominal blank → Gall bladder
Left side, third abdominal blank → Stomach
Right side, first abdominal blank → Pancreas
Left side, fourth abdominal blank → Small Intestines
Right side, second abdominal blank → Large Intestines
Bottom left blank → Rectum
Bottom right blank → Anus

Wait, that's 12 blanks. Let me verify with the actual image structure.

Since I need to be precise, let me use the zoom tool to examine specific regions.
