Respiratory Tract
In space and astronautical engineering, the respiratory tract refers to the system of organs and tissues involved in breathing and gas exchange during spaceflight. The respiratory tract includes the nose, mouth, throat, trachea, bronchi, and lungs. In microgravity environments, the respiratory system can be affected by changes in air pressure, humidity, and temperature, as well as by the accumulation of carbon dioxide and other pollutants. Astronauts must undergo rigorous training and medical evaluations to ensure that their respiratory systems are functioning properly before, during, and after spaceflight. Additionally, spacecraft and habitats must be designed to maintain optimal air quality and circulation to support the health and safety of crew members.
