Answer:
Blood can not be called as colloid.One of the properties of colloidal particles is they do not settle down on standing in the suspension and can not be separated through normal filtration or by centrifuging.Blood cells can be separated from plasma by these two ways.The negative charge (zeta potential) on the cells helps to avoid collision between them, while in circulation.
