10 Questions
What is the function of the cilia in the respiratory system?
To push out unwanted particles present in the inhaled air
How are the walls of the alveoli designed for efficient gas exchange?
Extremely thin and moist to allow for faster diffusion of gases
What is the role of the bronchi in the respiratory system?
To lead into the right and left lungs respectively
Why is the wall of the trachea strengthened by C-shaped rings of cartilage?
To prevent it from collapsing
What happens to carbon dioxide and oxygen during gas exchange in the alveoli?
