Calcium Homeostasis
Calcium homeostasis refers to the maintenance of a stable concentration of calcium ions in the extracellular fluid within a narrow range, which is essential for normal physiological function. In space and astronautical engineering context, calcium homeostasis is particularly important for astronauts, as they experience significant changes in calcium metabolism during spaceflight due to the absence of gravity and other environmental factors. These changes can lead to bone loss, muscle weakness, and other health issues. Therefore, understanding and maintaining calcium homeostasis is crucial for the health and well-being of astronauts during space missions.
