Let's solve this worksheet step by step. The task is to match the correct organ from the list with its corresponding function.
Organs provided:
- esophagus
- small intestine
- rectum
- gallbladder
- stomach
- anus
- large intestine
- mouth
- pancreas
Now, let’s go through each description and match it to the correct organ:
---
1.
Breaks food into small pieces with the help of the teeth and saliva.
→ This happens in the
mouth, where chewing (mastication) breaks food down, and saliva begins chemical digestion.
✔ Answer: mouth
2.
Carries food from the mouth to the stomach.
→ The
esophagus is the tube that transports food from the mouth to the stomach via peristalsis.
✔ Answer: esophagus
3.
Churns and mixes food with digestive juices that have acids and enzymes.
→ The
stomach performs mechanical churning and mixes food with gastric juices (containing hydrochloric acid and pepsin).
✔ Answer: stomach
4.
Produces enzymes that are released into the small intestine to help with digestion.
→ The
pancreas produces digestive enzymes (like amylase, lipase, proteases) and releases them into the small intestine via the pancreatic duct.
✔ Answer: pancreas
5.
Stores the bile the liver produces, releases bile into the duodenum to help digest fats in the food you eat.
→ The
gallbladder stores and concentrates bile produced by the liver and releases it into the duodenum when needed.
✔ Answer: gallbladder
6.
Digests and absorbs proteins, fats, and carbohydrates.
→ The
small intestine is the main site for digestion and absorption of nutrients. It receives enzymes from the pancreas and bile from the gallbladder.
✔ Answer: small intestine
7.
Absorbs salt and water from food, leaving a soft mass called stool.
→ The
large intestine (colon) absorbs water and electrolytes from indigestible food matter, forming feces (stool).
✔ Answer: large intestine
8.
Acts as the stool's temporary storage.
→ The
rectum holds feces until defecation.
✔ Answer: rectum
9.
Where stool exits the body.
→ The
anus is the opening at the end of the digestive tract through which stool is expelled.
✔ Answer: anus

Final Answers:
1. mouth
2. esophagus
3. stomach
4. pancreas
5. gallbladder
6. small intestine
7. large intestine
8. rectum
9. anus
