Disease and disorders of the respiratory system include all of the following except
a. lung cancer.
b. stroke.
c. asthma.
d. emphysema.

b. stroke.

Explanation:

Lung cancer: cancer is when the cells start to grow out of control crowding out normal cells and causing problems in the lungsStroke: it occurs when the blood supply to the brain is reduced or interrupted killing cells due to the lack of oxygen and nutrients.Asthma: is a condition where the airways in the lungs inflame intermittently narrowing them.Emphysema is the gradual damage of lung tissue (specifically alveoli)

Considering this information we can conclude that only the stroke occurs out of the respiratory system because it affects the brain.

I hope you find this information useful and interesting! Good luck!
