Heart is Primarily Not a Pump

DR TOM COWAN points out that heart is not a pump. DR GERALD POLLACK (“EZ Water” / 4th phase of water (gel) explains how the overwhelming majority of capillary flow is accomplished.
Dr Tom Cowan pointed out that when human ventrical constricts / ‘pumps’ the aorta (main blood artery exiting the heart making an immediate 180-degree bend) also constricts, opposite of the expected expansion. When a bent or coiled garden hose is suddenly pulsed with water it tends to expand towards straightness; unusually, the aorta does the opposite and constricts tending more towards a bend. Heart is a vortice-folded muscle, per DAN WINTER.
Think of heart as more of a one-way valve in a system requiring a ‘ram pump’. It is a blood-ratchet. There seems to be some pumping and also vortexing, but the majority of blood flow in a body is accomplished by means of capillary flow inherent to water per Dr Gerald Pollack.
