👉 The Association Fluid, often abbreviated as AF, is a fluid component of the blood that plays a crucial role in maintaining blood viscosity and flow dynamics. It is primarily composed of plasma proteins, such as fibrinogen, immunoglobulins, and various other proteins, which are released from damaged endothelial cells or platelets into the circulation. These proteins contribute to the fluid's ability to adapt its viscosity in response to changes in shear stress, a property known as rheopectasy, which helps ensure efficient blood flow through various vascular systems. The Association Fluid's ability to modulate viscosity is particularly important in conditions of low shear stress, such as in capillaries, where it prevents excessive clotting and maintains adequate perfusion.
