Lab 13 The Respiratory BIO202
L
System
Student Name: Monilola Anigala
Access Code (located on the lid of your lab kit): AC-I731J5
Pre-Lab Questions
1. Name two functions of the nasal cavity mucosa.
The nasal cavity mucosa protects the respiratory system by humidifying and filtering the
inhaled air.
2. Why is the trachea reinforced with cartilaginous rings?
The trachea is fortified with cartilaginous rings that act as a scaffold, preventing it from
collapsing and ensuring unobstructed airflow during respiration.
3. Describe the path a molecule of oxygen takes to get to body tissue, starting with the nares.
An oxygen molecule's journey through the respiratory system begins with inhalation through
the nostrils and culminates in diffusion into the bloodstream at the alveoli, paving the way
for its delivery to body tissues.
4. What is asthma?
Asthma is a persistent respiratory ailment characterized by inflamed and constricted airways,
resulting in recurring episodes of wheezing, coughing, and breathing distress.
