Deformation of red blood cells and the viscoelastic properties of a concentrated red cell suspension. 1984

T Murata

The viscoelastic properties of a concentrated red cell suspension in which red cells do not form rouleaux are discussed from a theoretical point of view. An elastic spherical shell filled with a viscous fluid is considered as a model of a normal red cell. A cell method is used to consider finite concentration of suspended particles. On the assumption that the deformation from a spherical shape is very small, the shape of a deformed shell in a shear flow and the constitutive equation of the suspension are derived.

UI	MeSH Term	Description	Entries
D008954	Models, Biological	Theoretical representations that simulate the behavior or activity of biological processes or diseases. For disease models in living animals, DISEASE MODELS, ANIMAL is available. Biological models include the use of mathematical equations, computers, and other electronic equipment.

D001809	Blood Viscosity	The internal resistance of the BLOOD to shear forces. The in vitro measure of whole blood viscosity is of limited clinical utility because it bears little relationship to the actual viscosity within the circulation, but an increase in the viscosity of circulating blood can contribute to morbidity in patients suffering from disorders such as SICKLE CELL ANEMIA and POLYCYTHEMIA.
