Abstract
A few drops of blood in a glass tube
and a blood smear on a glass slide can begin
to unfold the hidden mysteries of the
body.
Blood is actually moving tissue, and as
such, it touches all parts of the body. As
it reaches these areas it becomes modified
by them. Its composition includes living
cells, the red blood cells and the white
blood cells, which reflect what is happening
to the body, or somatic, cells they
contact as they act out their role in blood
function. The plasma fluid that bathes
and transports them becomes altered in
specific gravity, chemical composition,
and even appearance as it interacts with
the fluid that surrounds and is inside the
various body cells such as brain or bone
cells.
