What triggers the start of the body's respiratory system?

• Central nervous system

• Autonomic nervous system

What happens to the diaphragm and intercostal muscles when the body prepares to take in oxygen-rich air?

• Both diaphragm and intercostal muscles contract

• Both diaphragm and intercostal muscles flatten

• Diaphragm contracts and intercostal muscles flatten

• Diaphragm and intercostal muscles remain unchanged

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

• Transporting oxygen to the body's cells

• Expanding the lungs to create more space

• Dividing into thousands of tinier passages

• Exhaling carbon dioxide from the body

What is the purpose of the alveoli in the lungs?

• To produce red blood cells

• To transport oxygen throughout the body

What is the basic process by which oxygen and carbon dioxide are exchanged in the lungs?

• Diffusion

• Active transport

• Filtration

• Osmosis

How is oxygen transported throughout the body?

• Through the bronchioles

• Via the autonomic nervous system

• Via the bloodstream

• Through the alveoli

What happens to the carbon dioxide in the lungs?

• It is inhaled into the body

• It is expelled from the body

• It is converted into oxygen

• It is stored in the alveoli

What causes the diaphragm and intercostal muscles to compress the lungs?
