Space Environment:
It occurs in space, particularly aboard orbiting spacecraft like the International Space Station (ISS), where astronauts experience weightlessness.
Reduced Gravity:
Microgravity refers to the condition where objects appear to experience very low or near-zero gravitational force.
Definition:
Microgravity refers to the condition in which objects appear to be weightless and experience very little gravitational force. This happens in environments like space, where the gravitational pull from Earth is weak due to the distance from the planet.
Impact on the Human Body:
Prolonged exposure to microgravity can lead to physiological changes such as muscle atrophy, bone density loss, fluid redistribution (leading to a "puffy face" in astronauts), and cardiovascular deconditioning.
