Answer:
B. Reduce lung volume and reduce gas diffusion rates in the lungs
Step-by-step explanation:
Smoking causes tar to accumulate in the alveoli, preventing them from expanding to take in air during inhalation. How would tar accumulation affect lung volume and gas diffusion rates in the lungs?
Increase lung volume and increase gas diffusion rates in the lungs
Reduce lung volume and reduce gas diffusion rates in the lungs
Increase lung volume and reduce gas diffusion rates in the lungs
Reduce lung volume and increase gas diffusion rates in the lungs
