The wall of the alimentary canal is built from how many basic tissue layers?

  1. 6
  2. 4
  3. 3
  4. 5
Show answer and solution

Correct answer: B. 4

1. The layers are named from inside outward. 2. Mucosa, submucosa, muscularis and serosa are listed. 3. So there are 4 layers. _Source: OpenStax Anatomy and Physiology 2e, Chapter 23, The Digestive System._
