The only language where such sounds are known to be contrastive in normal vocabulary is the extinct ritual language Damin (also the only language outside Africa with clicks); however, Damin appears to have been intentionally designed to differ from normal speech.
The lungs expand and contract during the breathing cycle, drawing air in and out of the lungs. The volume of air moved in or out of the lungs under normal resting circumstances (the resting tidal volume of about 500 ml), and volumes moved during maximally forced inhalation and maximally forced exhalation are measured in humans by spirometry. [12]
The three types of ingressive sounds are lingual ingressive or velaric ingressive (from the tongue and the velum), glottalic ingressive (from the glottis), and pulmonic ingressive (from the lungs). The opposite of an ingressive sound is an egressive sound, by which the air stream is created by pushing air out through the mouth or nose. The ...
In birds and mammals, lungs are located above the diaphragm. The presence of an exceptionally well-preserved fossil of Sinosauropteryx, with lungs located beneath the diaphragm as in crocodiles, has been used to argue that dinosaurs could not have sustained an active warm-blooded physiology, or that birds could not have evolved from dinosaurs.
This is created by producing an air bubble between the left (or right) upper jaw and the cheek that can act as an alternative "lung". The person then uses muscular action to drive the air through a small gap between or behind the teeth into the mouth. The sound so produced makes a high rough sound. This then is articulated to make speech.
In postural drainage, the patient's body is positioned so that the trachea is inclined downward and below the affected chest area. [9] The body is positioned so that secretions drain into sequentially larger bronchi. [5] Frames, tilt tables, and pillows may be used to support patients in these positions. [1] [6] Up to 12 postures may be used. [10]

The air moves from outside the body through the tracheostoma directly to the lungs, without passing through the upper respiratory organs of the nose, mouth, and throat. Because it bypasses the vocal folds, speech can be severely impaired, and the development of an esophageal voice becomes necessary.
