Question

question 1
which of the following shows the correct sequence of airflow through the respiratory system?
a trachea, bronchi, lungs, alveoli, bronchioles bloodstream
b esophagus, bronchi, bronchiole, lungs, bloodstream, alveoli
c mouth, throat, esophagus, bronchi, bronchioles, alveoli
d mouth, throat, trachea, bronchi, bronchioles, alveoli
e esophagus, trachea, lungs, diaphragm, alveoli

question 2
breathing through the normal drinking straw simulated what breathing feels like to ____
a an asthmatic
b a smoker
c a person with copd
d an athlete

Explanation:

Question 1: The esophagus is part of the digestive system, not respiratory, so B, C, E are incorrect. A has alveoli before bronchioles (reverse order). D follows the correct respiratory airflow path: mouth → throat (pharynx/larynx) → trachea → bronchi → bronchioles → alveoli.
Question 2: A normal straw narrows the airway, simulating asthma where bronchoconstriction restricts airflow. Smokers/COPD involve lung damage (not just airway narrowing), athletes have enhanced breathing.

Answer:

Question 1: D. Mouth, throat, trachea, bronchi, bronchioles, alveoli
Question 2: A. An asthmatic
