Lab 13 The Respiratory System BIO202L
Student Name:
Access Code (located on the lid of your lab kit):
Pre-Lab Questions
1. Name two functions of the nasal cavity mucosa.
Moistens, warms and also filters the air.
2. Why is the trachea reinforced with cartilaginous rings?
Because, it help the passageway stay open, even when there is too much force caused by
breathing.
3. Describe the path a molecule of oxygen takes to get to body tissue, starting with the nares.
Nose (nares) pharynx epiglottis larynx in the trachea
4. What is asthma?
Narrowing/swelling of the airways.
