Abstract
According to the classic Windkessel model,
arterial system is assumed to be an elastic
chamber that only acts as a channel and buffer
for blood circulation, and heart is the only
power source. The Studies have shown that
the heart of a healthy person at rest pumps 5
- 6 L/min of blood, and the amount of blood
needed is 7.6 - 9.1×103 Kg per day, however,
cardiac output power at rest is only about 0.9
to 1.9 W. It's impossible for the heart pump
blood through the entire body by such low
power. We believe that there are other sources
of energy in the body for blood circulation,
including that from the active elastic arterial
system.
