What is a key feature of vesicular breathing?

Vesicular breathing is characterized by a lower pitch and a softer quality compared to bronchial breath sounds. This type of breath sound is typically heard over the lung fields and represents the normal air movement through the alveoli.

The softer intensity of vesicular breath sounds results from the ability of the lungs to filter and modify the airflow, which diffuses as it moves through the peripheral lung tissue. This is in contrast to bronchial sounds, which are typically louder and higher in pitch as they originate from the central airways, where sound is not dampened as much by surrounding tissue. Therefore, the distinguishing qualities of vesicular breathing, such as its softer volume and lower pitch, signify normal lung function and air exchange in the alveoli, making this answer accurate.

Other options incorrectly describe characteristics associated with different breath sounds or patterns that do not apply to normal vesicular breathing.
