Hengitysfunktiona
Hengitysfunktiona refers to the process of breathing, which is essential for life. It encompasses both the physical mechanics of respiration and the physiological exchange of gases within the body. The primary goal of breathing is to supply oxygen to the body's cells and to remove carbon dioxide, a waste product of cellular metabolism.
The process of breathing involves two main phases: inspiration (inhalation) and expiration (exhalation). During inspiration, the
Expiration is typically a passive process. The diaphragm and intercostal muscles relax, causing the thoracic cavity
Once air reaches the alveoli, the tiny air sacs in the lungs, gas exchange occurs. Oxygen from
