Question

Asthma is a disease of the lungs that affects the bronchial tubes. Asthma attacks can be triggered by smoke, pollen, exercise, and cold air. When exposed to a trigger, the smooth muscle rings in the bronchial tubes become constricted and inflamed. The image below shows a healthy bronchial tube and one from a person during an asthma attack. How would an asthma attack most likely affect oxygen delivery in the body? A. Oxygen delivery would be decreased due to a decrease in blood flow. B. Oxygen delivery would be decreased due to a decrease in air intake. C. Oxygen delivery would be increased due to an increase in blood flow. D. Oxygen delivery would be increased due to an increase in air intake.

Answer 1

The answer is actually "Oxygen delivery would be decreased due to a decrease in air intake." (B)

One, I have asthma, and two, I got this question right on the test xD

Answer 2

B. Oxygen delivery would be decreased due to a decrease in air intake.

Step-by-step explanation:

Asthma is a chronic disease caused by inflammation of the bronchi. Such inflammation causes airway closure, which causes decreased air intake in the body and ends up impairing breathing due to reduced oxygen delivery. Its symptoms are: dry, irritating cough, wheezing, chest discomfort and shortness of breath. With this we can state that the correct answer to your question is the letter B.

Asthma is one of the most common respiratory diseases worldwide. There are at least 300 million people with asthma worldwide and a mortality rate that reaches 250,000 patients per year.
