SCB 115 Lab 10 Exercise 17 – Respiratory System

Learning Objectives

After completing this lab, the students will be able to:

  • identify the structures of the respiratory system.
  • know the pathway of air from outside the body to the site of gas exchange in the lungs and the structures involved.
  • understand the mechanism of breathing.
