What is the difference between heart sounds and lung sounds?

I'm curious about the distinction between heart sounds and lung sounds. Could you elaborate on the key differences between these two types of bodily sounds? Heart sounds, presumably, are related to the rhythmic contractions of the heart muscle, while lung sounds seem to involve the breathing process. Are there any specific characteristics or patterns that distinguish one from the other? Additionally, how do doctors or healthcare professionals utilize these sounds during physical examinations? I'm interested in understanding the significance of these sounds in diagnosing potential health issues.
