hengitysvirrat
Hengitysvirrat, or breathing currents, describe the movement of air through the respiratory tract during breathing. In physiology the term refers to the pattern and rate of air flow between the atmosphere and the lungs as driven by pressure differences. The concept is also used in building engineering to refer to controlled indoor air movement created by ventilation systems.
In the human respiratory system, inspiration occurs when respiratory muscles contract, enlarging the thoracic cavity and
Clinical relevance: Disturbed hengitysvirrat are characteristic of respiratory diseases. Asthma and COPD increase airway resistance and
Environmental context: The term also describes air movement in buildings, influenced by ventilation design, temperature differences,
