If blood behaved like a true suspension, its larger particles would settle when left undisturbed. In blood, the dispersed phase consists of blood cells and the dispersion medium is plasma, remaining dispersed throughout.
Blood is an example of a colloidal mixture. (i) What would happen if blood behaved like a true suspension inside the body? (ii) In a blood sample, identify the dispersed phase and the dispersion medium.

If blood behaved like a true suspension, its larger particles would settle down when the blood was left undisturbed, rather than remaining dispersed. Blood is actually a colloid. In a blood sample, the dispersed phase consists of the dispersed blood cells and other particles, while plasma acts as the dispersion medium in which these particles are suspended. Centrifugation can separate blood components based on their properties.
