The diagram of the digestive system online exercise for | Live ... - Free Printable

Let's solve the labeling task for the Structure of the Digestive System diagram.

We are given a diagram with numbered labels (1 to 12), and we need to match each number to the correct organ from the list provided:

Organs List:

- Mouth
- Salivary Glands
- Epiglottis
- Esophagus
- Stomach
- Liver
- Gall Bladder
- Pancreas
- Small Intestine
- Large Intestine
- Rectum
- Anus

Now, let’s identify each labeled part based on standard human anatomy:

---

Step-by-step identification:

1. Label 1 – Points to the mouth
→ Mouth

2. Label 2 – Points to glands near the mouth (under the jaw)
→ Salivary Glands

3. Label 3 – Points to the large organ on the upper right side (above the stomach)
→ Liver

4. Label 4 – Points to the small green sac attached to the liver
→ Gall Bladder

5. Label 5 – Points to the lower end of the digestive tract, where waste exits
→ Anus

6. Label 6 – Points to the long coiled tube below the stomach (main site of nutrient absorption)
→ Small Intestine

7. Label 7 – Points to the wider tube surrounding the small intestine (where water is absorbed)
→ Large Intestine

8. Label 8 – Points to the organ just below the esophagus, holding food temporarily
→ Stomach

9. Label 9 – Points to the organ behind the stomach, releasing enzymes into the small intestine
→ Pancreas

10. Label 10 – Points to the tube connecting the throat to the stomach
→ Esophagus

11. Label 11 – Points to the flap that covers the windpipe during swallowing
→ Epiglottis

12. Label 12 – Points to the rectal area, just before the anus
→ Rectum

Final Answer Key:

| Number | Organ |
|--------|-------------------|
| 1 | Mouth |
| 2 | Salivary Glands |
| 3 | Liver |
| 4 | Gall Bladder |
| 5 | Anus |
| 6 | Small Intestine |
| 7 | Large Intestine |
| 8 | Stomach |
| 9 | Pancreas |
| 10 | Esophagus |
| 11 | Epiglottis |
| 12 | Rectum |

Explanation:

This diagram illustrates the human digestive system, showing how food moves through the body. The process starts at the mouth, where digestion begins. Food travels down the esophagus, enters the stomach for mechanical and chemical breakdown, then moves to the small intestine for nutrient absorption. The large intestine absorbs water, and the remaining waste passes through the rectum and out via the anus.

Accessory organs like the liver, gallbladder, and pancreas help in digestion by producing bile and digestive enzymes.

The epiglottis prevents food from entering the airway during swallowing.

✔ So, fill in the blanks as follows:

1. Mouth
2. Salivary Glands
3. Liver
4. Gall Bladder
5. Anus
6. Small Intestine
7. Large Intestine
8. Stomach
9. Pancreas
10. Esophagus
11. Epiglottis
12. Rectum
