Spacesuits for Astronauts

The astronauts wear spacesuits when they go out for a walk or work in space. These suits are essential for astronauts to survive in space where no oxygen is available for breathing and the weightlessness is likely to discontinue supply of blood to brain leading to unconsciousness. These suits will allow continuous supply of oxygen to the men who wear it and also protect them from radiations from space and severe changes in temperature. These suits completely insulate the body of the astronauts. These have hollow cavities which are filled with air. In the absence of these spaces blood may get collected in the lower half of the body.
