Microgravity Induced Changes

Microgravity, like that experienced in space, reduces the Earth's gravitational pull on the body, leading to various physiological changes. Without normal gravity, muscles weaken and shrink since they're used less. Bones lose minerals and become less dense, increasing fracture risk. Fluids in the body shift upward, affecting eye shape and brain pressure. The cardiovascular system adapts, potentially causing fainting or decreased endurance. Additionally, immune responses and cellular functions can be altered. These changes highlight how gravity influences bodily functions and underscore the importance of countermeasures during extended space missions.
