Bone Marrow
Bone marrow is a thick, spongy kind of jelly inside your bones.
Bone marrow makes all kinds of blood cells: red blood cells
that carry oxygen, white blood cells that fight infections, and
platelets that help blood clot.
X-ray
X-rays are special pictures of the inside of your body. A doctor
will decide when you need an X-ray and what body part needs
to be X-rayed. An X-ray machine, not a camera, is used to
take these pictures. When the picture comes out, it won’t like
the ones in your photo album, but doctors have learned how
to look at these pictures. Doctors can see broken bones, lung
infections, and more. Superman may have X-ray vision, but
your doctor has an X-ray machine!
Cancer
Cancer is a disease that happens when the body makes cells that
are not normal. These cells grow very quickly to take over the
normal cells and can spread to different parts of the body if a
doctor doesn’t treat it. People can get very sick from cancer and
even die. There are many different types of cancer, but you can’t
get any of them from being near someone who has it. But you
can get some kinds of cancer from smoking, so that’s another
good reason to say no to cigarettes!
