Inside-Out Anatomy: The Digestive System | Worksheet - Free Printable

Let’s go through each part of the digestive system as labeled in your worksheet. We’ll match each number to its correct description based on what happens in that organ.

---

1. Salivary glands
These are under your tongue and in your cheeks. They make saliva, which starts breaking down food right in your mouth — especially starchy foods like bread or potatoes.

✔ Correct match: *glands in the cheeks and under the tongue which produce saliva to moisten food so it is chewed*

---

2. Esophagus
This is the tube that carries food from your mouth to your stomach. It uses muscle movements (called peristalsis) to push food down — even if you’re upside down!

✔ Correct match: *muscular tube which moves partially eaten food from the mouth down towards the stomach*

---

3. Stomach
Your stomach is like a stretchy bag that holds food and mixes it with strong acids and enzymes to break it into smaller pieces.

✔ Correct match: *muscular organ which churns food and secretes enzymes and acids for food digestion*

---

4. Small intestine
This long, coiled tube is where most nutrients get absorbed into your blood. The inner walls have tiny bumps called villi to help soak up nutrients.

✔ Correct match: *hollow tract where intestinal enzymes optimize absorption and nutrients are absorbed into the bloodstream*

---

5. Pancreas
This organ makes juices full of enzymes that help digest carbs, proteins, and fats. It sends these juices into the small intestine.

✔ Correct match: *organ which secretes enzymes for starch and protein digestion into the small intestine*

---

6. Liver
The liver does many jobs — one big job is making bile (which helps digest fat), cleaning toxins out of your blood, and storing extra nutrients.

✔ Correct match: *organ which processes digested food into useful substances for the body, secretes bile for fat digestion, and removes harmful toxins from the blood*

---

7. Gall bladder
This little sac sits under the liver and stores bile until you eat fatty food — then it squirts bile into the small intestine to help break down fat.

✔ Correct match: *storage sac for bile located on the lower surface of the liver*

---

8. Colon (large intestine)
After the small intestine, leftover stuff goes here. The colon soaks up water and turns waste into solid poop.

✔ Correct match: *main part of the large intestine which absorbs water from undigested food*

---

9. Rectum
This is the last stop before poop leaves your body. It holds the waste until you’re ready to go to the bathroom.

✔ Correct match: *final section of the large intestine which eliminates waste material from the body*

---

All matches are now correctly paired with their descriptions.
