hemorheology

Hemorheology is the study of the flow properties of blood. It examines how blood flows through blood vessels and the factors that influence this flow. This field encompasses the physical characteristics of blood and its components, such as red blood cells, white blood cells, platelets, and plasma.

Key aspects of hemorheology include blood viscosity, which is the resistance of blood to flow. Factors affecting viscosity include the concentration of red blood cells (hematocrit), the deformability of red blood cells, plasma protein levels, and shear rate. Blood flow is also influenced by the elasticity and size of blood vessels.

Abnormalities in hemorheological properties can contribute to various diseases. For example, increased blood viscosity is often observed in conditions like polycythemia, diabetes mellitus, and cardiovascular diseases, potentially leading to impaired blood flow and tissue oxygenation. Conversely, conditions affecting red blood cell deformability, such as sickle cell anemia, can cause blockages in small blood vessels.

The study of hemorheology is important for understanding the pathophysiology of numerous diseases and for developing diagnostic and therapeutic strategies. Research in this area aims to improve treatments for conditions related to microcirculation and blood flow disorders.
