Question

how does passive breathing differ from breathing for phonation in regards to anatomy and physiology?

Answer 1

In the physiological point of view, Passive breathing is the type of breathing as the diaphragm contracts , it increases its length and the diameter of the chest cavity and then the lungs is expanded. The lungs will expand more in passive breathing than that of active breathing.

In the physiological point of view , the phonation is defined as the sound is produced when the vocal cord oscillates, and when the sound is produced by vocal folds, then the sound is filtered through vocal tract.

In the anatomical point of view, during passive respiration, during the forced inhalation phase, large amount of oxygen is occupied in the lungs by expanding the wall of the lung. The thoracic cage gradually increases in its size and the respiratory muscle come to action during the process.

In anatomical point of view, the phonation or phonatory process occurs when the air is expelled from the lungs through the glottis and it creates a pressure in the larynx. When the pressure is increased, the vocal folds starts to oscillate.
