Blood কোন ধরনের fluid?

The provided answer is correct because blood behaves like a Non-Newtonian fluid. Here’s a brief explanation to help you understand:

    
• Newtonian fluids, like water, have a constant viscosity regardless of the applied stress or shear rate.
    
• Non-Newtonian fluids, on the other hand, change their viscosity when stress or shear is applied. Blood is a prime example of this. Its viscosity can change based on factors such as shear rate, temperature, and the concentration of cells in the blood.
    
• This characteristic allows blood to flow easily through small vessels under different conditions, which is essential for its function in the body.

In summary, because blood does not have a constant viscosity and changes its flow properties under different conditions, it is classified as a Non-Newtonian fluid.
