Biology Regents Practice - Respiratory System

When you inhale, which structure first filters and moistens the air that enters the body?

• Trachea

• Alveoli

• Cilia in the nose

• Bronchioles

The exchange of oxygen and carbon dioxide between air and blood in the lungs occurs primarily in the:

• Diaphragm

• Bronchi

• Alveoli

• Larynx

An athlete experiences damage to the diaphragm muscle. What is the most likely immediate effect on their respiratory system?

• Decreased ability to filter dust from inhaled air

• Inability to exchange gases in the alveoli

• Impaired ability to inhale and exhale air

• Difficulty producing sounds in the larynx

Analyze how the different parts of the respiratory system work together to ensure that oxygen is efficiently delivered to the body’s cells, and describe what might happen if one part fails.

Some diseases and pollutants can damage the cilia lining the respiratory tract. Evaluate how damage to the cilia can affect both the process of respiration and overall health. Support your answer with evidence.
