Explanation / Answer

1) The peanut may be lodged in trechea as it is swallowed into the wind pipe. It will obstruct the airway and impair breathing process. As the epiglottis failed to onstruct the food partical entering the airway, the peanut is lodged in trechea as its diameter is about 2 centimeter. And peanut cannot move further into bronchi having small diameter.
Hence, option B)

2) The trechea divided into Right and left primary bronchi, that moves inside right and left lungs respectively.
Hence, option E)

3) As the diameter of airway is decreased, the walls become more muscular to maintain the bronchomotor tone. The muscular linings help the narrow passage to contract and dilate properly as well as support them to remain open.
Hence, option C)

4) In asthma attack, antihistamines are to be administered to counteract the effect of histamine that caused bronchoconstriction. As, histamines are responsible for allergic reactions, it creates symptoms of asthma, antihistamine works to dilate the bronchi and relieve asthma.
Hence, option B)
