First off: what exactly is a non-Newtonian fluid? Well, as its name suggests, it's the exact opposite of a Newtonian fluid. A Newtonian fluid is easy - it's defined by Newton as the perfect fluid, where its viscosity is influenced mostly by its temperature and pressure.

The fluid mosaic model was proposed by S.J. Singer and Garth L. Nicolson. This model explains the structure of the plasma membrane of animal cells as a mosaic of components such as phospholipids, proteins, cholesterol, and carbohydrates. These components give a fluid character to the membranes.

What is hypovolemia? Hypovolemia occurs when you don’t have enough fluid (blood) volume circulating in your body. A low volume of fluid could include water, blood (plasma) in your circulatory system and/or lymphatic fluid. Lymphatic fluid is a liquid substance full of white blood cells that helps remove toxins and waste from your body.
