Physical properties of blood include:
- blood pressure – the pressure exerted by the blood on the vessel wall
- osmolality – the total amount of osmotically active particles in 1 kg of solvent weight,
- osmotic pressure – the pressure, that must be applied to a sulotion to prevent osmosis,
- oncotic pressure – osmotic pressure of colloidal solution (blood plasma proteins),
- tonicity – osmolality of the solution in relation to plasma; we differentiate isotonicity, hypertonicity and hypotonicity,
- viscosity – viscosity of blood, depends mainly on hematocrit,
- flow – laminar and turbulent,
- Hagen-Poiseuille law – flow dependence on viscosity and tube proportions,
- blood flow velocity.
