Lungs
In the context of space and astronautical engineering, lungs refer to the respiratory system of humans and animals that are used to breathe in oxygen and exhale carbon dioxide. In space, the lack of gravity causes fluids to shift towards the upper body, including the lungs, which can lead to changes in lung function and capacity. Astronauts must undergo rigorous training and medical evaluations to ensure their lungs are healthy and can withstand the stresses of spaceflight. Additionally, spacecraft must be equipped with proper air filtration and circulation systems to maintain a breathable atmosphere for the crew. Understanding the effects of microgravity on lung function is important for long-duration space missions and the development of countermeasures to mitigate any negative impacts.
