Answer:
Why blood oozes out when there is a slight cut:
The body has many blood vessels that carry blood to and from the heart. Some of these blood vessels are very close to the skin. When we have a slight cut, the cut damages these blood vessels and so the blood they are carrying comes out of the wound.
This will be stopped when platelets form blood clots which then trapped blood cells and stop the bleeding.
Why Astronauts wear a special space suit:
When astronauts are in space and have to leave the spaceship, they face many unknown dangers in space such as radiation, debris and extremely cold weather. The space suit they wear is designed to protect them from all these so that they are able to stay alive in space and carry out their jobs.
