Ein Mann sitzt in einem Wald auf einem Koffer und hält den Becher einer Thermoskanne in einer Hand. Er blickt in die Ferne, zwischen Bäumen hindurch - vor seinem Gesicht verdunstet eine Atemwolke.

Respiratory system

The air passes through the mouth and nose, down the throat, past the larynx and vocal cords, and through the bronchial tubes into the lungs. From there, oxygen is released into the blood. Conversely, carbon dioxide is released from the lungs into the respiratory system for exhalation. Respiratory system disorders can hinder this vital process – and thus affect the body as a whole.
