1.5 Epithelium in the gut

Look at some actual tissue samples for different parts of the gut.

Activity 2

Open the virtual microscope [Tip: hold Ctrl and click a link to open it in a new tab. (Hide tip)] in a new window or tab.

Examine Slides 3–5 from the ‘Week 2’ category within the virtual microscope.

The slides depict sections taken from the stomach (fundus region), illeum and colon, respectively. Spend a few minutes looking at the samples and note the different types of epithelium lining the tissue.

In each case, aim to identify the typical structures that denote the three main layers of gut tissue:

  • the mucosa

  • the submucosa

  • the smooth muscle of the muscularis externa.
