The viscosity of blood refer to The viscosity of blood refer

Solution

ANSWER:

The viscosity of blood is referred to the resistance offered to the flow of blood due to the thickness or the stickiness of blood. The viscosity of blood determines the ability of blood to flow though the vessels.The blood viscosity in a normal adult human is 40/100 millipoise. Various factors affecting the viscosity of human blood are :

1. Deformability of RBCs,

2. Aggregation of RBCs,

3. Hematocrit,

4. Temperature and

5. Plasma viscosity; which in turn is affected by the -

In a healthy adult, a normal hematocrit is of 40-45%, and at this condition the relative viscosity of blood is 4-5 as compared to water.

At the normal temperature of 37 C, the coefficient of viscosity of blood is 0.0027 N-s/m²
