Respiratory System Quiz

During a biology class, Benjamin, Noah, and Priya were discussing the major function of the respiratory system. According to them, what is the primary role of the respiratory system?

• To supply the body with nitrogen

• To supply the body with water

• To supply the body with oxygen

• To supply the body with carbon dioxide

Anika, Aria, and Samuel are studying human anatomy. They are curious about the function of the paranasal sinuses. Can you help them understand?

• To produce mucus that flows into the nasal cavity

• To filter, heat, and moisten the air

• To provide an airway for breathing

• To produce oxygen for the body

During a biology class, Benjamin was asked to explain the function of the larynx. He said:

• It produces an airway and serves as the site of voice production

• It filters the air and removes impurities

• It produces carbon dioxide for the body

• It stores excess oxygen for the body

Nora, Avery, and Abigail are learning about the human respiratory system in their biology class. Their teacher asks, 'What is the function of the trachea in our body?'

• It stores excess carbon dioxide for the body

• It divides into primary bronchi

• It produces mucus for the lungs

• It provides an airway for breathing

Aiden, James, and Abigail are studying the human respiratory system. They learned about a part called the alveoli. Can you help them understand the function of the alveoli?

• To exchange gases within the lungs

• To store excess carbon dioxide for the body

• To filter the air and remove impurities

• To produce oxygen for the body

Aria, Kai, and Avery are studying human anatomy. They are discussing the function of the visceral pleura and parietal pleura. Can you help them understand its function?

• To provide an airway for breathing

• To surround the lungs and lie in close contact with the ribs

• To produce mucus for the lungs

• To divide the lungs into lobes

Jackson, David, and Sophia are studying for their biology exam. They learned that when we breathe, there's a certain pressure that helps our lungs to stay open. What is this pressure called?

• Intrapulmonary pressure

• Divisional lobe pressure

• Carbon dioxide storage pressure

• Oxygen production pressure

Avery, Nora, and Ava are studying the human respiratory system. They learned that when the inspiratory muscles are active, what happens?

• There is no change in volume or pressure

• There is a decrease in pressure and an increase in volume

• There is a decrease in volume and an increase in pressure

• There is a change in volume and a change in pressure

Ethan, Charlotte, and Kai are learning about the human body in their biology class. Their teacher asks, 'What is the function of ventilation, or breathing, when you are running in a marathon?'

• To store excess carbon dioxide for the body

• To allow air to enter along the pressure gradient

• To provide an airway for breathing

• To produce oxygen for the body

Elijah, Anika, and Charlotte are studying the human respiratory system. They are discussing what happens when the inspiratory muscles relax. What do you think they concluded?

• Expiration occurs

• Inspiration occurs

• The lungs close

• No change occurs
