label digestive systems worksheet - worksheetszone - Free Printable

The task is to label the parts of the digestive system in the provided diagram using the terms listed on the left side. Below is the solution with explanations for each part:

Solution:

1. Oral cavity: This is the mouth, where digestion begins with chewing and saliva.
- Label it at the top of the diagram near the head.

2. Pharynx: This is the throat, which connects the mouth to the esophagus.
- Label it just below the oral cavity.

3. Esophagus: This is the tube that transports food from the pharynx to the stomach.
- Label it as the vertical tube leading down from the pharynx.

4. Stomach: This is a muscular organ that stores food and mixes it with gastric juices.
- Label it as the large, curved organ in the upper abdomen.

5. Liver: This organ produces bile, which helps digest fats.
- Label it as the large, brownish organ located above the stomach.

6. Gallbladder: This small sac stores and releases bile produced by the liver.
- Label it as the small, green sac near the liver.

7. Pancreas: This organ produces enzymes that help digest carbohydrates, proteins, and fats.
- Label it as the light-colored organ located behind the stomach.

8. Duodenum: This is the first part of the small intestine, where most chemical digestion occurs.
- Label it as the short, coiled section of the small intestine near the stomach.

9. Large intestine: This is where water is absorbed, and waste is formed.
- Label it as the larger, looped section of the intestine.

10. Rectum: This is the final part of the large intestine where waste is stored before elimination.
- Label it as the straight section of the large intestine leading to the anus.

11. Anus: This is the opening through which waste leaves the body.
- Label it as the opening at the end of the rectum.

12. Salivary glands: These glands produce saliva, which helps moisten food and begin carbohydrate digestion.
- Label them near the oral cavity (mouth).

13. Epi-glottis: This flap of tissue prevents food from entering the trachea (windpipe) during swallowing.
- Label it near the pharynx, slightly above the esophagus.

Final Labeled Diagram:

- Oral cavity: Top of the diagram
- Pharynx: Just below the oral cavity
- Esophagus: Vertical tube leading down from the pharynx
- Stomach: Curved organ in the upper abdomen
- Liver: Large, brownish organ above the stomach
- Gallbladder: Small, green sac near the liver
- Pancreas: Light-colored organ behind the stomach
- Duodenum: Short, coiled section near the stomach
- Large intestine: Looped section of the intestine
- Rectum: Straight section leading to the anus
- Anus: Opening at the end of the rectum
- Salivary glands: Near the oral cavity
- Epiglottis: Near the pharynx

Explanation:

Each part of the digestive system plays a specific role in breaking down food and absorbing nutrients. By labeling the diagram correctly, you can visualize how these organs work together to process food from ingestion to elimination.
