Now we come to the inside approach of the fetal position during Paralysis. The dorsal vagus is the tenth cranial nerve and is also called the pneumogastric nerve, because it paradoxically shuts down all life supporting organs in order to keep the body alive as long as possible with no help from outside. Breath, circulation, temperature, digestion, secretion and so on is limited to an absolute minimum.
An important part of this shut down mechanism is the closing of all doors connecting the outside world with the inside world. Literally mouth and nose as intakes are shut down, and anus and urinary bladder as the outlets. Even the face is hiding between the knees, representing the shut down of all senses as gateways for impulses from the outside world.
This is actually done with the active help of a lot of muscles. Not only is the head kept in position with the help of all the neck muscles. The mouth is kept closed too.
The less obvious in terms of life sustainability are the partaking muscles inside the body. As the first one we could mention the heart, which comes at no surprise.
Heart and Circulation
Circulation is managed by the heart. Managed, not pumped. Blood pressure management comes much closer, to what the heart does, than do pumping. Well, actually there is not really any pumping going on.
To understand this, we start out listening to the embryo. It´s tissue is of course building up from the very first moment of fertilization, where the one original cell starts to double it self. Soon thereafter the circulation begins. This means, in this tiny creature, the body fluids starts circulating, all though there is no heart! They flow without heart. This flow of blood functions totally sufficient to ensure the thriving growth of the embryo.
Although the heart is the first organ to build, it is not until the third week, that a heartbeat can be registered. Se the picture above1.
Some few weeks later the basis for the four chamber construction is recognizable, but still there are no valves in the heart to ensure the suction needed for pumping function.
From picture 25 it becomes clear, that the very complicated structure of the heart originates in two strait muscle fibres, each one surrounding one tube, that eventually are fused and twisted into the sophisticated s-formation.
The picture below2 shows these muscles in the full developed heart.
It is not until right after the birth – and yes, you got it right: Not until after the child is actually born! – that the function of the heart, as we know it, is established. The final cornerstone is the closing of an opening between the left and the right half of the heart. Actually a recognizable number of children become problems, because this hole does not close adequately!
This should make it clear, that through all these nine months of living in the womb, the heart has not been pumping at all, simply because a pump, with out the adequate membrane to secure the pressure, is not capable of pumping. The fluid in question would simply slosh forth and back instead of being forced to flow in one direction.
Another mostly overlooked fact is, that wast amounts of lifeforms on earth live all life through with no trace of a heart or a similar organ. And yet fluids circulate and nourish the body. This holds true for any plant and even the biggest trees passing tons and tons of juice up to a height of more than one hundred meters and back deep into the ground penetrating roots.
But also endless species of animals live perfectly happy without a heart. Just think of sponges, sea anemones, corals, sea combs and all kinds of worms. And no, the are not minute all of them. The giant clam, tridacna gigas, is known to weigh several hundred kilos, more that most humans, for a comparison.
Verifiably every second one decilitre of blood passes through the heart. That is 300 litres every hour or more that 7 cubic meters per day, which is an overwhelming amount of blood passing through this little organ.
An adult human heart3 weighs in at about 300 grams. It is 6-8 cm wide, or almost the size of a fist. The walls of the pressure chambers at the thinnest are below 10 mm, indicating which kind of pressure, this delicate muscle is meant to withstand. See picture 27. Although the valves are equipped with reinforced cusps, they are even thinner and work seemingly effortless.
Where the heart sits at the very centre of circulation, the capillaries are at the the outer fringes of it. We call it circulation and we may think of the system of veins and arteries as one whole tubing system. It is not. There is no connection between veins and arteries! Apart from the heart, they compose two very different and isolated systems!
Where as the tubing character of the arteries is obvious and easy to detect in arms and legs, as soon as they meet an organ or muscle, they split up and disappear. Literally. From the artery the blood comes pulsing and you might expect it to find tunnels everywhere. It does not. It diffuses into the tissue.
Maybe you have enjoyed meat at your dinner plate or even prepared it? Try to imagine forming a tiny pit in such a lump of flesh. Now in your imagination, fill this pit with water. What would happen, would it seep through? Of course not. Now imagine taking such a piece of meat to the mouth and try to press some water from your mouth through the meat. Do you think you would succeed? I suppose not.
This is the situation: There is no tubing leading the blood around in the body. There are two systems – actually with the lymph there are more – the arteries and the veins, but they only meet at the centre, the heart, not at the periphery.
The painful fact is, that the blood has a way higher viscosity than water and the capillaries are as tiny or smaller than the red blood cells passing through. Obviously the blood stream passes through each and every cell in the body. Cells that are not nurtured, would very quickly die of.
Now take your attempt to an other level. Take a dead pig and connect an electric pump to the arteries in stead of the heart, and start the motor. How big do you think this motor has to be in order to make the blood pas through the dead body of the pig?
Maybe it is the wrong question. Because it is never going to happen, regardless of how big the pump is. The artery walls will explode way before penetration on a cellular level occurs.
So how does blood flow without the heart pumping it? There is only one logical explanation: Like before the heart started working, like in trees and other plants, like in shells and worms, the body liquids most be driven around without the pumping function, without pressure. That means suction.
