The Correct Answer is A
A. The hilum is the region on the medial side of the lung where the bronchus, blood vessels, and nerves enter and exit the lung.
B. The epiglottis is a flap of tissue that covers the trachea during swallowing to prevent food from entering the airways, but it is not related to the entry of structures into the lung.
C. The nares are the nostrils through which air enters the respiratory system, not the area where the bronchus and vessels enter the lung.
D. The conchae (also known as turbinates) are structures inside the nasal cavity that help warm and humidify air, not related to the lung’s entry point.

A. The epiglottis is a flap of cartilage located at the base of the tongue that covers the trachea (windpipe) during swallowing. This directs food and liquids into the esophagus and prevents them from entering the airway.
B. The conchae (or turbinates) are structures inside the nasal cavity that help warm and humidify air, not related to swallowing food or liquids.
C. The glottis is the opening between the vocal cords that leads to the trachea, but it is not responsible for directing food into the esophagus.
D. The Adam's apple is part of the larynx and is primarily related to voice production, not swallowing.
Correct Answer is B
Explanation
A. Capillaries are small blood vessels that are involved in the exchange of gases but are not part of the bronchial tree.
B. The bronchiole is the smallest division of the bronchial tree. It is a narrow airway that connects the larger bronchi to the alveoli, where gas exchange occurs.
C. Arterioles are small blood vessels that are part of the circulatory system, not the respiratory system.
D. The alveoli are the small air sacs at the end of the bronchioles where gas exchange occurs, but they are not the smallest subdivision of the bronchial tree—this is the bronchiole itself.
