Answer 2

Blood is considered as a colloidal dispersion.

• The term colloidal refers to particles with at least one dimension ranging from 1nm to 1µm.
• A colloidal dispersion is composed of solid, liquid or gas particles dispersed in a continuous phase
• Most common colloidal dispersions are solid-liquid (suspensions), liquid-liquid (emulsions), gas-liquid (foams), and solid-gas (aerosols) dispersions.
• Colloidal stability relates to particle size change.
• Electrophoretic light scattering (ELS) is a common technique used to evaluate the potential of dispersion to remain stable.
• ELS allows measuring zeta-potential of a dispersion, which provides information about electrostatic interactions
• oil in water are Emulsions used in moisturizing products and food products such as milk, mayonnaise and vinaigrette.
• An emulsion is a mixture of two or more liquids that are normally immiscible.
• Blood is a colloid because in blood the blood cell size is between 1nm to 100nm.
• It has blood cells, nutrients, minerals, etc. which are the dispersed phase, and the dispersing medium is plasma.
• The plasma is the liquid part of blood that consists of salts, water and many proteins.
• The solid part of the blood consists of formed elements.
• The mixture is also called a colloidal solution, colloidal system, or colloidal dispersion.
• The liquid portion of the blood, the plasma, is a complex solution containing more than 90 percent water.
