Blood & Respiratory

Respiratory System Lab

Purpose:

The purpose of this lab is to become familiar with the anatomy and physiology of the respiratory system.

Materials:

To complete this lab you will need access to McGraw Hill’s Connect platform, and through it you can access the Cadaver Dissection Tool, also known as A&P Revealed.

Procedure:

Log in to Connect, and navigate to the Cadaver Dissection Tool. It will open automatically when you click on it. This is a memory-intensive program, so it is recommended that you close other windows and programs before attempting to utilize it.
