Assignment Overview

This practice exercise helps students understand the anatomical structures of the respiratory system.


A one- to two-page (250- to 500-word) paper

Step 1  Explain three difficult concepts. 

As you review the information presented in this lesson and the textbook, identify the three most difficult concepts (or parts of a concept) in respiratory anatomy and respiration for most anatomy and physiology students. Select one difficult concept from each of these topic areas:

  • Anatomy of the Respiratory System
  • Mechanics of Breathing
  • Respiration

Step 2  Write an explanation of each concept. 

Write a clear one-paragraph explanation of each of these three concepts. Use images from the Internet or those that you scan into the document, if possible. At a minimum, submit a one- to two-page (250- to 500-word) paper.
