Figure 39.7 Which of the following statements about the mammalian respiratory system is false?
- When we breathe in, air travels from the pharynx to the trachea.
Introduction:
In the respiratory system, the air enters into the body through nostrils to nose. This nostril has two nasal cavities with hair and mucus. In this cavity, airs is filtered and maintain its temperature according to body temperature. Next air passes through pharynx, and removed germs here and further air moves to larynx then trachea. In trachea again air is filtered by mucus. Finally two bronchi made of extent form of trachea and further air pass by each of one leads to lung.
Answer to Problem 1VCQ
Correct answer:
Correct answer is option (b) the bronchioles branch in to bronchi.
Explanation of Solution
Explanation/justification for the correct answer:
Option (c) is given as the bronchioles branch in to bronchi. Air pass from the cavity of the nasal passes using throat that known as the pharynx, further move to the voice box, which known as the larynx. Further air flows in order to reach the trachea and eventually air pass to bronchi and bronchioles that are present in lungs.
Explanation for incorrect answer:
Option (a) is given as when we breathe in, air travels from the pharynx to trachea, When we breath in, air travels from the pharynx to trachea, is a true statement. Hence, it is an incorrect answer.
Option (c) is given as alveolar ducts connect to alveolar sacs. Alveolar ducts connect to alveolar sacs is a true statement. Hence, it is an incorrect answer.
Option (d) is given as gas exchange between the lung and blood takes place in the alveolus. Gas exchange between the lung and blood takes place in the alveolus, is a true statement. Hence, it is an incorrect answer.
Thus, for mammalian respiratory system bronchioles branch in to bronchi is not true statement.
