Answer 2

When you are on Earth there is Air Pressure acting on you which counteracts the pressure applied by the blood vessels against the body. When you go to higher altitudes or to the outer space, there is less or no air pressure acting on your body which will make your blood vessels burst open. To counteract this space suits are used. Diving suits also you the same concept but in a different way. The pressure outside is more will kill you, so, diving suits balances it. Space suits also are used to provide oxygen and also they protect us from the UV and Infrared rays from the Sun which are filtered by the Ozone Layer.
