Our body is accustomed to high atmospheric pressure on ground. If we encounter, a low atmospheric pressure as is the case on high altitude we will experience the bursting of body cells, bleeding of nose and a high blood pressure. But in space, where astronauts dare to travel, atmospheric pressure does not exist at all. How do they cope with such condition?

Answer:

There is no external pressure in space. Astronauts, while travelling through space, wear heavy space suits so as to create an external pressure. These space suits prevent the bursting of body cells and bleeding of nose and ears.
