Auscultation (based on the Latin verb auscultare "to listen") is the term for listening to the internal sounds of the body, usually using a stethoscope. Auscultation is performed for the purposes of examining the circulatory system and respiratory system (heart sounds and breath sounds), as well as the gastrointestinal system (bowel sounds).
The term was introduced by René-Théophile-Hyacinthe Laënnec. The act of listening to body sounds for diagnostic purposes has its origin further back in history,
