Hyperpnea – fast and deep breathing; Hyperventilation – increased breathing that causes CO 2 loss; Hypopnea – slow and shallow breathing; Hypoventilation – decreased breathing that causes CO 2 gain; Labored breathing – physical presentation of respiratory distress; Tachypnea – increased breathing rate
Respiration is the rhythmical process of breathing, in which air is drawn into the alveoli of the lungs via inhalation and subsequently expelled via exhalation. When a human being inhales, air travels down the trachea, through the bronchial tubes, and into the lungs. The entire tract is protected by the rib cage, spine, and sternum. In the ...
Breath: The New Science of a Lost Art is a 2020 popular science book by science journalist James Nestor.The book provides a historical, scientific and personal examination of breathing, with a specific interest in contrasting the differences between mouth breathing and nasal breathing.
The differences between the atmospheric and intrapulmonary pressures, driving air in and out of the lungs during the breathing cycle, are in the region of only 2–3 kPa. [18] [19] A doubling or more of these small pressure differences could be achieved only by very major changes in the breathing effort at high altitudes.
In mammals, physiological respiration involves respiratory cycles of inhaled and exhaled breaths. Inhalation (breathing in) is usually an active movement that brings air into the lungs where the process of gas exchange takes place between the air in the alveoli and the blood in the pulmonary capillaries.

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.
However, chronic mouth breathing leads to, or is a sign of, illness, and it does not have mucus in the mouth to trap the unwanted substance unlike the nostrils [5] [6] [7] They end in the microscopic dead-end sacs always opened, though the diameters of the various sections can be changed by the sympathetic and parasympathetic nervous systems.
Breathing is the repetitive process of bringing air into the lungs and taking waste products out. The oxygen brought in from the air is a constant, on-going need of an organism to maintain life. This need is still there during sleep so that the functioning of this process has to be automatic and be part of the autonomic nervous system .
