William's mother, a respiratory nurse student, came to talk with our class on Monday afternoon. As you can see in this picture, she brought in a model of the trachea and bronchial tree. She shared with the students about how the lungs work and the various illnesses that would cause patients to need respiratory treatments. The class loved seeing an oxygen masks and other equipment that is used in hospitals. Thank you for sharing your time and knowledge with us, Mrs. Morris!
