Your immune system is important in order to prevent your body from becoming
overwhelmed from all the bacteria,
viruses, and pathogens that we encounter every day.
It is a lot of work to run the
immune system smoothly on earth, but how
is the immune system affected when
humans are in space?
What would happen to a human that got too close to a black hole?  Stay tuned to find out.
To put things into perspective, the immune system is composed of specific organs,
cells, antibodies, and proteins that work
together to fight off infections. In
certain organs, cells are created or
stimulated. Some cells, particularly
B cells create antibodies. These
antibodies work to neutralize pathogens
and they assist cells in identifying
where pathogens are by sticking to the
bacteria or viruses. Cells communicate
through protein signaling. Everything is
tightly regulated and is amazingly
robotic. It is a fine-tuned process. When
humans go into space everything changes: gravity changes, you are exposed to more
radiation, you change your daily patterns.
All the stress and hormones that are
associated with that, affect the function
of your body and the function of your
immune system. The immune system quiets down as the body is too overwhelmed to
maintain it effectively. If you were
exposed to germs in space you would be
more likely to get sick and to show more
devastating indicators of infection. Before going into space, if you appeared healthy but were
fighting off an infection, and not
exhibiting symptoms, once in space you
would more likely show symptoms and
become ill. Even things that you were
exposed to years go, but your healthy immune system was
keeping it in check, could resurface and
cause you to suffer. This is because the
immune system will not run as
effectively. If you were to ever go into
space you would want to make sure that
you are completely healthy. Black holes
are in space and they have such a
gravitational pull that nothing could
escape from them.
While no human has ever gotten close to a
black hole or have entered one, if they
were to try to enter a black hole they
would most likely be obliterated and
their immune system would no longer
function. Don't forget to subscribe for
