Respiratory System Post Lab

What does the "clay" in the lung model represent?

• Diaphragm

• Chest cavity (chest opening)

• Lung

• Airway

What part of the lung model is represented by the "stretched balloon"?

• Diaphragm

• Chest cavity (chest opening)

• Lung

• Airway

In the lung model, what does the "straw" represent?

• Diaphragm

• Chest cavity (chest opening)

• Lung

• Airway

What is the function of the bronchioles in the respiratory system?

• They filter air before it goes into the lungs.

• They carry air in and out of the alveoli.

• They warm and moisten the air.

• They exchange gases directly with the blood.

Where are the alveoli located in the respiratory system?

• At the end of the bronchioles, deep within the lungs.

• Inside the nasal cavity, behind the nose.

• Throughout the lungs, extending from the bronchi.

• Behind the mouth and nasal cavity.

What is the primary role of the nasal cavity in the respiratory system?

• It is responsible for gas exchange.

• It filters, warms, and moistens air before it goes into the lungs.

• It carries air directly to the alveoli.

• It produces vocalizations.

What happens when the diaphragm muscle in humans contracts?

• The lungs exhale air.

• The lungs take in air.

• The heart rate increases.

• The blood pressure rises.

How is the model lung similar to the human respiratory system?

• Both exchange gases.

• Both use real muscles.

• Both involve air entering and leaving.

• Both have two lungs.

In the model lung, what causes air to enter when the balloon is pulled down?

• Increased air pressure inside the cup.

• Decreased air pressure inside the cup.

• The balloon expands automatically.

• The cup expands.

Which of the following is a difference between the model lung and the human respiratory system?

• The model lung uses a real muscle.

• The model lung is operated manually.

• The model lung has a higher capacity.

• The model lung uses electrical impulses.
