Answer:
A mixture,which is heterogeneous because it is made up of different solutes or components which are not uniform.Therefore when the mixture described in the question are viewed,the cells,ions,molecules mixed together varied from one region to another leaving phases(2 or more) that are separated from one another,with each components still retaining their original properties for easy identification.When these samples are taken out they show variation in their proportion of the components.
Thus blood cells will have their different phase,like wise,water,plasma, etc.
It is different from homogeneous mixture in which the components are uniform and appear in the same proportion,in one phase.
Note-the part of a sample mixture with the same properties and composition is called a phase.
