All of life moves about with a constant interplay between the forces of ions. Ions are electrically charged atoms or groups of atoms. Anions are the negatively charged ions and are created through an electron gain and cations are the positively charged ions created through an electron loss. In colloidal chemistry the term used to discuss the charge around a colloidal particle is zeta potential.

When tiny minerals or organic particles (colloids) are suspended in a fluid, the negative ionic charge around the colloid is what maintains the dispersion or discreteness of the particles of the suspension.

In blood, the amount of the suspended particles, the pH of the suspension, the mix of anions and cations, all determine the rheological characteristics. Rheology is the word that describes the study of the deformation and flow of matter. Rheo is from Greek and it means flow.

It is interesting to note how for thousands of years Chinese medicine has always dealt with the concept of flow. If you don't have flow then you must have congestion. If you have congestion then you don't have flow. It's the yin and yang of life. The up and down of balance. The in and out of health.
