Which term describes 'wet' or crackling sounds during lung auscultation?

Explanation:
Rales describe wet, crackling sounds heard when listening to the lungs. They arise when air moves through fluid in the small airways or when alveoli reopen after being collapsed. Fine crackles are high-pitched pops heard at the end of inspiration, while coarse crackles are deeper and longer. These sounds point to fluid in the lungs, as seen with pulmonary edema, pneumonia, or other interstitial processes. This helps distinguish them from wheezes (musical, continuous sounds from narrowed airways), rhonchi (low, snoring-like sounds from secretions in larger airways), and stridor (harsh, high-pitched sound from upper airway obstruction).
