Question 3 • 26-27 Ignite Health Science Concepts - EL3602
The lower respiratory system, especially the lungs and alveoli, moves oxygen into the blood and removes carbon dioxide. Damage can interfere with oxygen delivery, so A applies; it can also cause carbon dioxide to build up or be removed too quickly, changing the blood’s pH, so D applies. Blood movement to cells is mainly a circulatory-system function, and lung damage does not necessarily stop the surrounding muscles from working.
