During erythrocyte aggregation, red blood cells cluster together and clump together. The phenomenon is physiologic to some degree, especially in the smaller capillaries. In immune complex diseases, for example, this physiologic degree is exceeded. What is erythrocyte aggregation? In erythrocyte aggregation, red blood cells cluster together and clump together. Red blood cells are also called … Erythrocyte Aggregation: Function, Role & Diseases
The Fåhraeus-Lindqvist effect is a blood flow phenomenon based on erythrocyte fluidity and related to blood viscosity. Viscosity is lower in vessels of the circulatory periphery with a narrow lumen than in vessels with a higher lumen. The Fåhraeus-Lindqvist effect primarily prevents blood stasis in capillaries. What is the Fåhraeus-Lindqvist effect? The Fåhraeus-Lindqvist effect is … Fåhraeus-Lindqvist Effect: Function, Tasks, Role & Diseases
Blood viscosity corresponds to the viscosity of blood, which depends on parameters such as blood composition and temperature. Blood does not behave like a Newtonian fluid but exhibits nonproportional and erratic viscosity. Pathological changes in viscosity are present, for example, in hyperviscosity syndrome. What is blood viscosity? Blood viscosity corresponds to the viscosity of blood, … Blood Viscosity: Function, Tasks, Role & Diseases
The marginal flow of the blood is the blood flow in close proximity to the walls of the vessels. Especially in the smaller vessels, it is a plasmatic marginal current without leukocytes and erythrocytes, which has a much lower flow velocity than the central blood current. During inflammatory reactions, the marginal flow changes. What is … Marginal Current of Blood: Function, Tasks, Role & Diseases
Axial migration in blood flow causes deformable erythrocytes to displace into the axial flow by means of near-wall shear forces in smaller vessels. This creates low-cell marginal flows that prevent stenosis in capillaries. This effect is part of the Fåhraeus-Lindqvist effect and can be limited by changes in the shape of red blood cells (RBCs). … Axial Migration: Function, Tasks, Role & Diseases
Plasma viscosity and blood viscosity are not the same thing, but they are directly related. Plasma makes blood flowable because it is composed mainly of water. When cellular plasma components increase, blood may lose its physiologic viscosity. What is plasma viscosity? Plasma has special fluid mechanics that are determined by different forces. Viscosity is a … Plasma Viscosity: Function, Tasks, Role & Diseases
