Part 2: Histology of the Digestive System
- Obtain the slides listed below that are available for today’s lab.
- Focus on each sample and identify the structures listed for each type of tissue.
- Indicate the total magnification you make each illustration at in the space provided.
- Illustrate each tissue you observe with the microscope at the magnification you listed.
- Label each illustration with the structures listed for each.
Oral Cavity
Label the tissue with: stratified squamous epithelium, mucosa, lamina propria
Esophagus
Label the tissue with: mucosa, submucosa, muscularis externa, serosa, lumen, stratified squamous epithelium, lamina propria
Stomach
Make one illustration at a low magnification and another at a higher magnification to view structures in the mucosa.
Label the tissue with: mucosa, submucosa, muscularis externa, serosa, goblet cells, simple columnar epithelium lamina propria, gastric pits, gastric glands
Liver
Label the tissue with: lobule, portal canals, central veins, hepatocytes, sinusoids
Small Intestine
Make one illustration at a low magnification and another at a higher magnification to view structures in the mucosa.
Label the tissue with: mucosa, submucosa, muscularis externa, serosa, plicae circulares (circular folds), villi, simple columnar epithelium, lamina propria, goblet cells, microvilli
Large Intestine
Make one illustration at a low magnification and another at a higher magnification to view structures in the mucosa.
Label the tissue with: mucosa, submucosa, muscularis externa, serosa, simple columnar epithelium, lamina propria, goblet cells, intestinal glands, muscularis mucosa
Part 3: Digestive System Laboratory Activities
Oral Cavity, Esophagus, and Stomach
- Use the anatomical models provided to your group in your group.
- As a group, identify the structures listed below.
- Write each of the following structures on masking tape or labeling tape (with correct spelling) and stick onto the model to label each structure.

4. When you are done, take photos of your labeled anatomical model(s). Ask your instructor to verify the labeling is correct.

Liver, Gallbladder, and Pancreas
- Use the anatomical models provided to your group in your group.
- As a group, identify the structures listed below.
- Write each of the following structures on masking tape or labeling tape (with correct spelling) and stick onto the model to label each structure.

Flow of the Gastrointestinal Tract
1. As a group, determine the route a bolus/chyme/feces take through the digestive tract. List each structure of the alimentary canal in order. When the list is complete, show when it is called "bolus," when it is called "chyme," and when it is called "feces," by adding labels to your list.
