Respiratory sounds, also known as lung sounds or breath sounds, are the specific sounds generated by the movement of air through the respiratory system. [1] These may be easily audible or identified through auscultation of the respiratory system through the lung fields with a stethoscope as well as from the spectral characteristics of lung sounds.

Pneuma (πνεῦμα) is an ancient Greek word for "breath", and in a religious context for "spirit". [1] [2] It has various technical meanings for medical writers and philosophers of classical antiquity, particularly in regard to physiology, and is also used in Greek translations of ruach רוח in the Hebrew Bible, and in the Greek New Testament.
Real-time magnetic resonance imaging of the human thorax during breathing X-ray video of a female American alligator while breathing. Breathing (spiration [1] or ventilation) is the rhythmical process of moving air into and out of the lungs to facilitate gas exchange with the internal environment, mostly to flush out carbon dioxide and bring in oxygen.
An easy to understand example is a traumatic pneumothorax, where air enters the pleural space from outside the body, as occurs with puncture to the chest wall. Similarly, scuba divers ascending while holding their breath with their lungs fully inflated can cause air sacs to burst and leak high pressure air into the pleural space.
The sound is almost guttural and the aspirant is inhaled, not exhaled, air. Thus, for an English-speaker exhaling the response, the exhaled sound is not understood by native Samar-speakers. The American English trouble expression "uh-oh" does not approximate it. Eastern, Western, and Northern Samar have different accents in the same dialect.
The automatic rhythmical breathing in and out, can be interrupted by coughing, sneezing (forms of very forceful exhalation), by the expression of a wide range of emotions (laughing, sighing, crying out in pain, exasperated intakes of breath) and by such voluntary acts as speech, singing, whistling and the playing of wind instruments.
The rough breathing comes from the left-hand half of the letter H. [1] In some archaic Greek alphabets, the letter was used for , and this usage survives in the Latin letter H. In other dialects, it was used for the vowel [ ɛː ] ( Eta ), and this usage survives in the modern system of writing Ancient Greek , and in Modern Greek .
Various breathing abnormalities . Ataxic respirations are one of many unique respiration styles in an ill patient. There is an apparent controversy surrounding the novelty of ataxic respirations versus the well-known Cheyne-Stokes and cluster respirations, which Dr. Camille Biot deemed mutually exclusive. [3]
