human digestive system - ESL worksheet by carcarla - Free Printable

Let's solve the task step by step based on the image you've provided. The goal is to label the digestive system diagram and fill in the blanks in the accompanying text.

✔ Step 1: Label the Digestive System Diagram

We have a list of organs to label:

- SMALL INTESTINE
- RECTUM
- STOMACH
- MOUTH AND SALIVARY GLANDS
- TONGUE
- ESOPHAGUS
- LARGE INTESTINE
- LIVER
- PHARYNX
- TEETH
- APPENDIX

Now, match each part of the diagram with the correct label.

#### From top to bottom (based on the diagram):

1. Mouth (with teeth and tongue) → *MOUTH AND SALIVARY GLANDS*
- The mouth includes the lips, teeth, tongue, and salivary glands.
2. Esophagus → *ESOPHAGUS*
- The tube connecting the mouth to the stomach.
3. Stomach → *STOMACH*
- The J-shaped organ below the esophagus.
4. Liver → *LIVER*
- Located above the stomach, on the right side.
5. Small Intestine → *SMALL INTESTINE*
- Coiled tube inside the abdomen, connected to the stomach.
6. Large Intestine → *LARGE INTESTINE*
- The larger tube surrounding the small intestine.
7. Rectum → *RECTUM*
- The final section before the anus.
8. Appendix → *APPENDIX*
- A small pouch attached to the large intestine (usually near the cecum).
9. Pharynx → *PHARYNX*
- Located behind the mouth and nasal cavity; connects mouth to esophagus and larynx.

> Note: In the diagram, pharynx might be hard to see, but it’s the area just behind the mouth before the esophagus. It's often labeled as part of the throat.

So, labeling from top to bottom:

| Position | Label |
|--------|-------|
| 1 (top) | MOUTH AND SALIVARY GLANDS |
| 2 | ESOPHAGUS |
| 3 | STOMACH |
| 4 | LIVER |
| 5 | SMALL INTESTINE |
| 6 | LARGE INTESTINE |
| 7 | RECTUM |
| 8 | APPENDIX |
| 9 | PHARYNX |

> ⚠️ Note: The tongue and teeth are already shown within the mouth. They're part of the "mouth and salivary glands" category.

✔ Step 2: Fill in the Blanks in the Text

#### Paragraph 1:
> Most of the digestive organs, like the ________ and ________, are tubes.
> The digestive system is essentially a long, twisting tube that runs from the mouth to the anus.

✔ Answer:
Most of the digestive organs, like the esophagus and small intestine, are tubes.
(Other valid answers could be large intestine, rectum, etc., but "esophagus" and "small intestine" are best for this context.)

#### Section: The Start of the Process – The Mouth

> Food is broken down by the _______________ and by the chemical action of salivary enzymes.

✔ Answer:
Food is broken down by the teeth and by the chemical action of salivary enzymes.
*(Mechanical digestion by teeth, chemical by saliva)*

#### Section: On the Way to the Stomach – The Esophagus

> After the food enters the ________________________.
> The esophagus is a long tube that runs from the ________________ to the ________________.

✔ Answer:
After the food enters the pharynx.
The esophagus is a long tube that runs from the mouth to the stomach.

> 🔍 Explanation: After chewing, food is swallowed into the pharynx, then moves down the esophagus to the stomach.

✔ Final Answers Summary:

#### Diagram Labels (from top to bottom):
1. MOUTH AND SALIVARY GLANDS
2. ESOPHAGUS
3. STOMACH
4. LIVER
5. SMALL INTESTINE
6. LARGE INTESTINE
7. RECTUM
8. APPENDIX
9. PHARYNX

> *(Note: Pharynx is often located between the mouth and esophagus — so it may be drawn just below the mouth and above the esophagus.)*

#### Text Fill-ins:

1. Most of the digestive organs, like the esophagus and small intestine, are tubes.
2. Food is broken down by the teeth and by the chemical action of salivary enzymes.
3. After the food enters the pharynx.
4. The esophagus is a long tube that runs from the mouth to the stomach.

📌 Additional Notes:

- Salivary glands produce saliva containing amylase, which starts breaking down starch.
- The liver produces bile, which helps digest fats.
- The appendix is a small organ with no major digestive role (possibly immune function).
- The large intestine absorbs water and forms feces.
- The rectum stores feces until excretion.
