Question

A) inspiratory and expiratory neurons.
B) structures of the bronchial tree.
C) pharynx, larynx, and trachea.
D) pleural membranes.

Accepted Answer

The bronchial tree is the structure that allows air to enter and exit the lungs. This includes the bronchi and bronchioles that branch off from the trachea and lead to the alveoli where gas exchange occurs. The inspiratory and expiratory neurons are located in the brainstem and control the breathing process. The pharynx, larynx, and trachea are part of the respiratory system but are not specifically located within the lungs themselves. The pleural membranes are thin layers of tissue that surround the lungs and help to protect and cushion them.
