Describe the general composition and function of the plasma membrane?

it is mostly water with many dissolved solute such as: nutrient, gases, hormones and wastes. Most plasma protein are produced by the liver. Albumin which is 60% of plasma protein serves as blood buffer to plasma osmotic pressure( the pressure that helps to keep water in the bloodstream). Another function of is plasma distribute heat.
