What’s Water Got to Do With It?
Interestingly, the work of Gerald Pollack, author of “The Fourth Phase of Water,” was instrumental in helping Cowan understand the function of the heart and how blood flows if it isn’t being pushed or pumped by the heart.
First off, if any pumping action were to be involved, it would actually have to occur at the capillaries because that’s where the blood stops and needs to get moving again. However, the solution nature came up with is far simpler. As the blood moves up the venous tree, the blood vessels narrow and eventually coalesce to come back to the heart.
This narrowing of the vessels makes the blood flow faster, in and of itself. Valves and muscular contractions also play a role. However, the primary way blood moves has to do with water. As Pollack has described, water can exist in four phases, not just three. The fourth phase of water is formed by the interaction of water and a hydrophilic surface.
“What happens with that is you form a gel layer, or protective layer, on that hydrophilic surface, which is negatively charged. Therefore, the opposite of positive charge is dissolved into the bulk water in the middle of the tube (capillary or blood vessel) … All you need is a hydrophilic tube, which forms a gel layer, which is negatively charged, and then the bulk water is positively charged. The positive charges repel each other and that starts the flow going up the hill,” Cowan explains.
