How is exercise related to viscosity? exercise = viscosity

The flow of blood through the vessels of the circulatory
system is a function of the pressure in the system and the resistance to flow caused by
the blood vessels. Blood flow is directly proportional to pressure and inversely
proportional to resistance.

that is
Blood flow=
pressure/resistance

If the
pressure in a vessel increases then the blood flow will increase. However, if the
resistance in a vessel increases then the blood flow will decrease. Resistance in the
blood vessels is effected by three parameters:

1. Length of
the vessel. The longer the vessel the greater the
resistance.

2. Viscosity of the
blood. The greater the viscosity the greater the
resistance.

3. Radius of the vessel. The smaller the radius
the greater the resistance.

When you exercise, blood flow
to the skeletal muscles increases significantly (up to 80-85% of total blood flow).So,
viscosity
decreases.

Consequently, the blood flow to a
resting muscle is LOW, that means, viscosity is HIGH.
