Biological fluids

A fluid is a substance that is unable to withstand any stress, therefore continuously deforms. Biological fluids are fluids found in living organisms. There are many biological fluids such as blood, urine, sweat, breast milk, bile and cerebrospinal fluid. Blood is the most studied biological fluid. The first studies made about the circulation of blood were done around 2700 BC by the Yellow Emperor of China, Huang Ti. Density, viscosity, specific gravity and specific weight are important properties that allow the study of the behavior of those fluids (Waite 10). Biological fluid mechanics studies the physiologically relevant fluid flow phenomena, underlying physical mechanisms from an engineering perspective and is a part of Biomechanics. Biomechanics studies how the physical forces of biological fluids interact with living organisms (Ethier 1). This field of study is integrated into Bioengineering, which is the application of engineering to medicine and life sciences. Thanks to biological fluid mechanics many improvements regarding circulatory diseases were made in the past years (Mazumdar 5-6).
