Two more juices

The idea

Pancreatic juice is basic, neutralises acids and breaks down carbohydrates, proteins and fats; juice from the small intestine wall breaks fats, proteins and partially digested carbohydrates further into simpler forms.

Many helpers

Bile is not the only helper in the small intestine.

Which part also sends a juice that works on carbohydrates, proteins and fats?

• The pancreas
• The tongue
• The nose

• acidic. Pancreatic juice is basic. That is why it neutralises acids.
• neither acidic nor basic. It is basic, so it can neutralise acids.
• basic — correct. Yes!
• Pancreatic juice — correct. Yes!
• Bile. Bile breaks fats into tiny droplets, but pancreatic juice breaks down all three.
• Mucus. Mucus in the stomach protects its lining. It does not break down these nutrients.
• water. Water is already simple. It does not need to be broken down.
• partially digested carbohydrates — correct. Yes!
• plain stones. Stones are not food. The juice works on fats, proteins and partially digested carbohydrates.
• Both are acidic. Both are basic, not acidic.
