The Hydraulic Ram Model of the Heart
Clearly, if your heart stops beating, you won’t live very long, but if the heart isn’t actually pumping the blood, how does it work? In his book, Cowan describes the heart as a hydraulic ram, which he explains thus:
“What does the heart do? The blood is moving fast. It comes into the heart. The heart stops the blood, and like a hydraulic ram, it holds it back. The walls expand. The pressure differential happens, and then it opens the gate and comes out.
More so when the blood is in the heart, because of the unique shape of the heart … The heart is a vortex-creating machine … [I]t has these trabeculae (fibers) inside the heart. Each area of the trabeculae is connected with a certain part of the body.
[One] area of the heart is connected with the spleen, another area of the inner part of the heart is connected with the foot, and so on.
The blood comes in and these areas of the heart create their individual spirals, and package up certain parts of the blood, like the old red blood cells, into a vortex and send it to the spleen, whereas another part sends the fresh new red blood cells up to the brain.
If there’s a cut on your leg, it dissolves some of the inner fibers, puts that in a vortex and sends that to the cut on your leg. It’s so wild. Again, there’s an article about this on my website, as hard as it is to believe, that actually documents that in very clear terminology how this happens.”
