What is the role of alveoli in the respiratory system?

• Alveoli produce mucus in the respiratory system.

• Alveoli facilitate gas exchange in the respiratory system.

• Alveoli regulate blood flow in the respiratory system.

• Alveoli store oxygen in the respiratory system.

What is the main function of the diaphragm in respiration?

• To contract and flatten during inhalation, increasing thoracic cavity volume and allowing air to flow into the lungs.

• To produce sound for speech.

• To regulate the amount of oxygen entering the bloodstream.

• To expand and contract during exhalation, pushing air out of the lungs.
