The ability to study complex biological processes has greatly improved with the increasing speed and expanded storage capacity of modern computers, together with new advanced numerical methods and programming techniques. Bioengineering applies the methods of engineering, applied mathematics and physics to the study of biological phenomena, and the use of their concepts to describe these phenomena.

In addition, since fluids are one of the major components of a living organism, fluid mechanics play a major role in bioengineering, by analyzing and simulating the fluid flow problems associated with physiological processes.
