Blood circulation and magnetism
The body contains within it parts and substances that respond to magnetism. One obvious and important example is the blood circulatory system. Indeed not only does magnetism act on the blood, but the blood carries the effects of the magnetism to other parts of the body. To have a clearer picture of why this is so, one must first be familiar with the blood circulation process.
The average human being has something of the order of six litres of blood. These are pumped by the heart through the major outgoing blood vessels, namely the arteries and arterioles as well as the much smaller capillaries. These may be compared to roads. Thus, to use a British analogy, the arteries are like the motorways, the arterioles are the A roads and the capillaries are the B roads.
This oxygenated blood is carried not only to the brain, where it releases oxygen through the blood-brain barrier, but also to the organs and the cells. Indeed it is estimated that every cell in the human body is served by at least one capillary. These capillaries also carry the blood back to the venules and veins (the equivalent of the opposite lanes of the A roads and motorways, going in the other direction).
The returning blood is cleaned out by the kidneys and then transported to the lungs where it receives a new dose of oxygen. From there it goes back to the heart which starts pumping it round again.
The blood itself is a mixture of actual cells and plasma, the former accounting for slightly less than half and the latter for slightly more. The blood cells themselves can be red or white or so-called platelets. The red cells derive their red colour from a large molecule called haemoglobin. These cells have to be large because they each carry around with them a few atoms of iron, which is a much heavier element than the other elements in the red blood cells. It is this iron that gives blood its magnetic properties.
The iron is very important because it is this that gives the blood the ability to carry oxygen around the body. These magnetic products store the oxygen that all parts of the body need. If the number of red cells becomes too low – in a condition called anaemia – the person tends to become weaker through the lack of enough oxygen reaching the cells that need it.
Whilst magnet therapy cannot cure anaemia (it can often be cured by the right diet), it can improve blood circulation and thus improve the rate at which oxygen reaches the cells. Thus magnetic products can help the person in the meantime while the more gradual process of rebuilding the haemoglobin level goes to work more slowly.
