Unit 9 Practice Questions

Front

What is emphysema?

Back

A form of Chronic Obstructive Pulmonary Disease (COPD) characterized by chronic inflammation of the lungs, leading to an abnormal increase in air spaces near the bronchioles and accumulation of carbon dioxide, causing hyperventilation and a pink tone in the skin.

Front

What are conchae?

Back

Three bone-like structures inside the nasal cavity that increase the turbulence of airflow in the nasal passage.

Front

What is the cardiopulmonary system?

Back

The system that includes both the respiratory system and the cardiovascular system, working together to facilitate gas exchange and transport.

Front

What happens when cilia in the respiratory tract are damaged?

Back

There is an inability to sweep airway contaminants, leading to increased risk of infections and respiratory issues.

Back

To facilitate the exchange of oxygen and carbon dioxide between the body and the environment.
