Biofluid mechanics is a branch of science that deals with the study of fluids in biological systems, such as blood flow in the cardiovascular system, air flow in the respiratory system, and fluid dynamics in the human digestive system. It involves the application of principles from fluid mechanics to understand the behavior of fluids within living organisms and how they interact with biological tissues. Researchers in this field aim to improve our understanding of how biofluids flow through the body, as well as the mechanisms behind diseases and disorders related to fluid dynamics. This area of research is multidisciplinary, drawing on knowledge from physics, engineering, biology, and medicine.
