Discuss viscosity and how it relates to blood

What will be an ideal response?


Viscosity refers to the friction developed between the molecules of a fluid as they slide over each other during flow of the fluid. The thicker a liquid is, the greater its viscosity, the greater the resistance to flow. For example, molasses flows more slowly than water because molasses has greater viscosity. Blood viscosity is determined primarily by the number of circulating red blood cells. Normally, this factor is relatively constant and not important in controlling resistance. Occasionally, however, blood viscosity and resistance to flow are increased because an excessive number of red blood cells are present, in which case blood flow is more sluggish than normal.
