digestive system organs worksheet - worksheetszone - Free Printable

Let’s go step by step to solve this task.

We are given a list of organs and need to color them based on two categories:

- Blue circle: Accessory organs of digestion
- Red circle: A part of gastrointestinal tract

First, let’s understand what these mean in simple terms:

✔ Gastrointestinal (GI) tract = The main tube that food travels through — from mouth to anus. It includes: Mouth → Esophagus → Stomach → Small intestine → Large intestine → Rectum → Anus

✔ Accessory organs = Organs that help with digestion but food does NOT pass through them. They make juices or enzymes to break down food. These include: Liver, Pancreas, Gallbladder, Salivary glands

Now let’s go through each organ one by one:

1. Toungue → Actually, it should be “Tongue”. It’s inside the mouth and helps move food — so it’s part of GI tract → Red

2. Esophagus → Tube that carries food to stomach → Part of GI tract → Red

3. Large intestine → Where water is absorbed and waste forms → Part of GI tract → Red

4. Liver → Makes bile to help digest fat → Food doesn’t go through it → Accessory organ → Blue

5. Rectum → Holds poop before it leaves body → End of GI tract → Red

6. Mouth → Where digestion starts → First part of GI tract → Red

7. Pancreas → Makes digestive enzymes → Food doesn’t go through it → Accessory organ → Blue

8. Stomach → Breaks down food → Part of GI tract → Red

9. Gallbladder → Stores bile from liver → Accessory organ → Blue

10. Anus → Exit point for waste → Last part of GI tract → Red

11. Salivary glands → Make saliva to start breaking down food → Accessory organ → Blue

12. Small intestine → Most digestion happens here → Part of GI tract → Red

Wait — we have 12 items? Let me count again from the image layout:

Left column:
- Toungue
- Large intestine
- Rectum
- pancreas
- Gallbladder
- Saliavy glands → Should be “Salivary glands”

Right column:
- Esophagus
- liuer → Should be “Liver”
- Mouth
- stomach
- Anus
- Small intestine

Yes, 12 total.

Now assign colors:

🔴 Red (GI tract):
- Tongue
- Esophagus
- Large intestine
- Rectum
- Mouth
- Stomach
- Anus
- Small intestine

🔵 Blue (Accessory organs):
- Liver
- Pancreas
- Gallbladder
- Salivary glands

Double-check:

GI tract path: Mouth → Tongue (inside mouth) → Esophagus → Stomach → Small intestine → Large intestine → Rectum → Anus → ✔ All red

Accessory: Liver, Pancreas, Gallbladder, Salivary glands → ✔ All blue

Note: “Toungue” and “liuer” and “Saliavy” are typos — we treat them as Tongue, Liver, Salivary glands.

Final Answer:

Color the following RED (part of gastrointestinal tract):
- Tongue
- Esophagus
- Large intestine
- Rectum
- Mouth
- Stomach
- Anus
- Small intestine

Color the following BLUE (accessory organs of digestion):
- Liver
- Pancreas
- Gallbladder
- Salivary glands
