A blood sample contains several different types of cells, each of which contains different combinations of specific ions and molecules. The cells are suspended in water, and the water also contains many molecules and ions. Which term or terms could be used to describe this sample of blood

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.
