Understanding Microgravity Effects on Astronauts

Why is it crucial to study the effects of microgravity on the human body?

• To develop new medications

• To enable long-duration space travel

• To improve exercise routines on Earth

• To enhance astronaut communication

What happens to the body's fluid distribution in microgravity?

• Fluids shift towards the head

• Fluids move towards the feet

• Fluids remain evenly distributed

• Fluids evaporate quickly

What imaging technique is used to study fluid accumulation in astronauts' eyes?

• Magnetic Resonance Imaging (MRI)

• Optical Coherence Tomography (OCT)

• X-ray Imaging

• Ultrasound Imaging

What percentage of astronauts show early signs of fluid accumulation at the back of the eye?

• 30%

• 90%

• 50%

• 70%

How long can it take for vision changes to resolve after returning to Earth's gravity?

• 1 month

• 6 months

• 1 year

• 2 years
