WebPhysics questions and answers. Question 1: Diffusion statistics [40 pts] Human Serum Albumin (HSA) is the most abundant protein found in human blood plasma and is responsible for maintaining the oncotic pressure in blood vessels. A researcher at the University of Ottawa is interested in studying the properties of HSA with microfluidics. WebOne of the most important functions of albumin is to regulate the oncotic pressure of the plasma; that is, the pressure that attracts water (through the osmotic effect) into the blood vessels in order to counteract the capillary blood pressure that forces the water outwards. northeastern hyonho lee
