👉 An attractive fluid, often found in biological systems like blood or synovial fluid, is a type of viscous liquid that exhibits properties of both liquids and gases. It is characterized by its ability to flow easily under the influence of gravity or other forces while still maintaining a cohesive structure that allows it to cling to surfaces, such as the walls of blood vessels or joints. This unique behavior is due to the presence of dissolved particles, proteins, and other components that give the fluid its viscosity and stickiness. In blood, for instance, it helps transport oxygen and nutrients while also cushioning organs from mechanical stress. The term "attractive" refers to its tendency to adhere to surfaces, a property crucial for functions like lubrication and shock absorption in the body.
