The smooth muscles inside the blood vessels adjust to the micro gravity in order to work properly, the same way they work on Earth. Also the heart rate slows since the muscles of the legs are not in use due to the lack of gravity
He/she dies!
Their bodies would become very weak.
In weightlessness, an astronaut that "pretends" to throw an object may find his or her arm's sudden movement causes their body to rotate in the same direction. If they actually threw a mass, the forces would cause the astronaut to travel in the opposite direction.
The astronaut's space helmets allows them to breathe in space! It is connected to an air supply.An astronaut's space suit keeps him from harm from outer space objects!They live in an airtight environment (suit, ship, or station).
an astronaut.
the astronaut heart and muscles and bones shrink and get weaker ...this because: the earth's gravitational pull is strong so the heart pumps blood harder than it needs to in space so when a astronaut is in orbit it doesn't need to work so hard so they shrink. hope this helps.
Do you want to know what happens to the limb, the astronaut or the space programme?

the blood is always red . The red colour of the blood is caused by an iron compound hemoglobin. neither in earth nor in space hemoglobin could suddenly turn blue so the blood of the bleeding astronaut will always be red
an astronaut is someone that goes up in to space
Because blood is liquid, its boiling point is affected by pressure changes. Extremely low pressure would lower the boiling point enough that the blood would boil at a temperature less than body temperature.

Alan sheperd was the first astronaut in space.
To an astronaut in a space craft, the sky appears to be black.
