Biofluid mechanics is the study of behavior of flow of biological fluids in living organisms which in turn plays a crucial role in determining the state of the tissue. Biofluid mechanics has emerged as an important field in past few years it has been recognized how important flow behavior is to determine the effects on fluid as well as tissue. Fluids in living organisms include blood, water, air and bodily fluids of animals, as well as the fluids in plants.

Biofluid mechanics studies the movement and balance of forces in resting fluids and fluids in motion. Biofluid mechanics play a major role in the cardiovascular system and it is important to understand the forces and movement of blood cells and whole blood as well as the interaction between blood cells and the vessel wall.
