How does extreme temprature affect an astronaut

The temperatures in space can range from freezing cold to boiling hot, fatal both ways.

How does zero gravity affect bone density?

Since your bones don’t have to support the body against gravity. Your bones would no longer have a constant strain on them from things like walking and other daily tasks because of the lack of gravity. This causes bone density to lessen when in a zero-gravity environment for a prolonged time.

when in space, how long do astronauts have to workout for?

two and a half hours

How long does an astronaut need to heal before going back to work

about six weeks

what can ebullism do to a person?

at minimum it causes tissue swelling and bruising, and at worst it could block off an artery or blood vessel due to an air/gas bubble in the bloodstream.

100

how does zero gravity affect blood cells

It slows down the blood system

100

what is ebullism?

The reduced pressure of the environment lowers the boiling point of the fluid in the human body and causes the water in the blood and soft tissue to turn into water vapour

100

What does an astronaut have to do once they get home?

They have to go through hours of physical therapy

How does space radiation affect an astronaut 

The radiation in space that astronauts are exposed to puts them at risk for radiation sickness, increased risk of getting cancer, degenerative diseases, and effects on the central nervous systems in their lifetime. The radiation also causes direct damage to the DNA, through the interaction of charged particles with the DNA. All though the DNA more or less returns to its original state once removed from the stressful conditions of space, it will never be 100% the same after returning to Earth. There are still a lot of unknowns about the long term effects of space radiation.

How does zero gravity affect a person's muscles?

Your muscles weaken from not being constantly in use against gravity. You don’t really have to use your muscle a lot when you’re floating around in space. 

150

Does your blood boil in space

yes

150

What is the most common misconception about blood boiling in space?

It was believed by many that blood boils thanks to the extreme temprature which isnt true

How is space debris a possible threat to astronauts

If space debris happened to hit an astronaut, the impact could very well be fatal. Space debris could also destroy space shuttles and satellites, which could also be fatal to the astronauts and cost a lot of money.

How does zero gravity affect your immune system?

It weakens the immune system

200

What is the point of a space suit?

To be able to give a person air while out in space

200

name 3 mental changes an astronaut may be going through

  • Emotional and Interpersonal Issues

  • Anxiety and Depression

  • Excessive Alcohol Use 

  • Cognitive Problems (from extreme stress and space radiation)

  • Sleep Disturbances

What has the human body done to combat the scary depth of space

the human body had evolved to protect itself in cade something goes wrong

250

How does zero gravity affect your heart?

Your heart would weaken and shrink because it would no longer have to work against gravity to circulate blood. The heart is also conditioned to work against gravity so it works harder to send blood up than down, so when someone is living in an environment with no gravity, their faces get puffy and their legs become a lot thinner.

What causes your blood to boil in space?

The lack of atmosphere

What does zero gravity do to a person's spine?

It elongates the spine
