Step-by-step solution for: ? Digestion Experiment - Human Digestive System for Kids
To solve the problem, we need to match the descriptions in the left column with the correct anatomical structures or processes listed in the right column. Let's go through each description step by step:
---
- This describes the Mouth.
- The mouth is a hollow cavity that contains teeth, which grind and break down food into smaller pieces.
Answer: Mouth
---
- This describes the Tongue.
- The tongue has taste buds for tasting flavors and helps move food around during chewing.
Answer: Tongue
---
- This describes the Salivary glands.
- Salivary glands produce saliva, which moistens food and contains enzymes (like amylase) that begin breaking down carbohydrates.
Answer: Salivary glands
---
- This describes the Pharynx.
- The pharynx is a muscular tube that connects the mouth to the esophagus and helps propel food from the mouth to the esophagus.
Answer: Pharynx
---
- This describes the Esophagus.
- The esophagus is a muscular tube that uses peristaltic movements to push food from the pharynx to the stomach.
Answer: Esophagus
---
- This describes the Stomach.
- The stomach mixes food with gastric juices (containing hydrochloric acid and enzymes like pepsin) to break it down into a semi-liquid substance called chyme.
Answer: Stomach
---
- This describes the Pancreas.
- The pancreas produces pancreatic juice, which contains enzymes like lipase (for fats), amylase (for starches), and proteases (for proteins).
Answer: Pancreas
---
- This describes the Liver.
- The liver produces bile, which emulsifies fats to aid in their digestion and absorption.
Answer: Liver
---
- This describes the Gallbladder.
- The gallbladder stores and concentrates bile produced by the liver until it is released into the small intestine when needed.
Answer: Gallbladder
---
- This describes the Small intestine.
- The small intestine is the primary site of nutrient absorption, where digested nutrients are absorbed into the bloodstream.
Answer: Small intestine
---
- This describes the Large intestine.
- The large intestine absorbs water from the remaining indigestible material and forms feces.
Answer: Large intestine
---
- This describes the Rectum.
- The rectum is the final part of the large intestine where feces are stored until they are expelled through the anus.
Answer: Rectum
---
Here is the completed matching:
1. Hollow cavity where teeth are housed and food is ground → Mouth
2. Allows us to taste flavors and helps move food around to be chewed → Tongue
3. Secretes saliva that moistens and helps break down food → Salivary glands
4. Tube that connects the mouth to the esophagus → Pharynx
5. Muscle tube that connects the pharynx with the stomach → Esophagus
6. Organ where food is mixed and broken down into liquid mixture → Stomach
7. Produces juice to break down fats, sugars, fats, and starches → Pancreas
8. Secretes bile for digestion and absorption → Liver
9. Stores bile produced by the liver until needed → Gallbladder
10. Absorbs nutrients from already digested food → Small intestine
11. The last structure to process food, absorbs remaining water → Large intestine
12. Final section of the large intestine, rectum stores feces until expulsion → Rectum
