hengitystoiminta
Hengitystoiminta refers to the physiological processes involved in breathing, the exchange of gases between an organism and its environment. This vital function ensures the supply of oxygen necessary for cellular respiration and the removal of carbon dioxide, a metabolic waste product. The process can be broadly divided into ventilation and gas exchange.
Ventilation, or breathing, is the mechanical movement of air into and out of the lungs. In mammals,
Gas exchange occurs in the alveoli, tiny air sacs in the lungs. Here, oxygen from inhaled air
In humans, the respiratory system, comprising the nose, pharynx, larynx, trachea, bronchi, and lungs, facilitates this
