kopsufunktsioon

Kopsufunktsioon refers to the physiological processes and capabilities of the lungs. It encompasses the mechanisms of breathing, the exchange of gases, and the overall health and efficiency of the respiratory system. The primary function of the lungs is to facilitate the uptake of oxygen from the inhaled air into the bloodstream and the removal of carbon dioxide, a waste product, from the blood into the exhaled air. This vital process is essential for cellular respiration and the survival of the organism.

The mechanics of breathing involve the coordinated action of the diaphragm and intercostal muscles, which alter the volume of the thoracic cavity, leading to changes in lung pressure and the flow of air. Lung volumes and capacities, such as tidal volume, inspiratory reserve volume, and vital capacity, are key metrics used to assess the functional status of the lungs. Pulmonary function tests, like spirometry, are commonly employed to measure these parameters and diagnose various respiratory conditions.

Beyond gas exchange, the lungs also play roles in other bodily functions, including vocalization, filtering inhaled particles, and regulating the pH balance of the blood. The intricate structure of the lungs, with millions of alveoli, provides an enormous surface area for efficient diffusion of gases. Maintaining healthy lung function is crucial for overall well-being and is influenced by factors such as air quality, lifestyle choices, and the absence of disease.
