Identify each structure labeled in the diagram.

oral cavity

stomachpancreas

small intestine

rectum

gall bladder

large intestine

1. Where does protein digestion begin?

2. What is the function of F?

3. Where are nutrients absorbed into the blood?

In the stomach

Absorb water

In the small intestine

4. What does C produce? Where does it go?

5. What is the function of G?

6. Chemical digestion is completed in this structure.

7. What type of digestion occurs in A?

Pancreatic juiceGoes to the small intestine

store bile

small intestine

mechanical and chemical

1.What is the name of this process? What is its function?

2.Where in the digestive tract does this occur?

•peristalsis•To push food through the digestive tract

esophagus, stomach, small intestine, large intestine

1.What is structure F? What is the function of this substance?

2. What occurs in structure B?

3. What is the function of structure A?

•liver •to produce bile

chemical digestion of proteins

The esophagus pushes food down into the stomach using peristalsis.

1.Through which of these structures does food pass?

2.Which organs are not part of the gastrovascular tract? How do they aid in digestion?

Esophagus (A)Stomach (B)

Small intestine (D)

•Liver (F) – produces bile that goes to the SI•Gall bladder (E) – stores bile•Pancreas (C) – releases pancreatic juice into SI

Describe the role of the small intestine in digestion.

•Where most chemical digestion occurs

•Where chemical digestion is completed

•Lined with VILLI which absorb nutrients into the blood
