The flow behavior of biological fluids in living organisms plays a cru
cial role in determining the state of the tissue through which they fl
ow. Biofluid mechanics, the study of the fundamentals of biological fl
uid flow, has been recognized to be extremely important for the unders
tanding of how changes in the flow behavior within living tissue maybe
affect both the fluid and the tissue. Fluids in Living tissue include
blood, mater, air and bodily fluids of animals, as well as the fluids
in plants. The movement and balance of forces in resting fluids and f
luids in motion are among the basic subjects for research. Biofluid me
chanics is a field whose importance to the field of bioengineering has
increased over the last two decades as pharmaceuticals, biomaterials
and non-invasive diagnostic and surgical procedures create changes in
the fluid mechanics of biofluids. Biofluid mechanics is a complex fiel
d including one of the most important areas of study-blood flow and ca
rdiovascular diseases.
