The son of Albion

In 1914-1915 Bainbridge in England had the courage to try a direct mechanical effect on the receptors of the heart. By this time it was already known that the Atria contain a huge number of sensitive nerve endings. To increase the pressure in the right atrium and call it stretching, Bainbridge used the rapid introduction of fluid in the veins. Heart responded to it by the frequent cuts. How to prove that this is the result of irritation of receptors of the heart? (Bainbridge assumed it receptors right atrium and hollow vein.) He, as Bezold, cut both wandering nerve, and after that intravenous administration of blood or physiological solution already had no effect on heart rate. Bainbridge believed that when the muscular load is increased venous return blood to the heart stretches right atrium, and in response heart responds increased blood into the aorta and the pulmonary artery. Bainbridge was satisfied with the results, and confirmed by experiment phenomenon (increased heart rate in response to increased pressure in the right atrium, that is in tension atrium high blood pressure) named reflex of Bainbridge. Everyone knows physiologist, engaged in the study of circulation, but not any psychologist knows for sure whether there is actually a reflex of Bainbridge.
The fact that the technique experience of Bainbridge simple, and dozens (if not hundreds) of scientists began to repeat the experiment. And then, it turned out that to some, everything works exactly as described Bainbridge, other't nothing: the heart does not respond to intravenous injection, the third heart ever to knock researchers confused: it responded with increased heart rate, he left all manipulations unanswered. There were also others, who found that the hyperextension of the Atria causes a reflex, diametrically opposite described by Bainbridge, and the fifth, who noticed that the dogs in chronic experiments after denervation of the heart (that is, in the absence of the sympathetic innervation and cut wandering nerves) while running heart is still racing, and hence came the conclusion that the response of the heart, veins stretching and fibrillation, due to work the muscle pump" is not a reflex, and the manifestation of the law of the Starling. This law is that the stronger the original tension of the heart muscle during diastole, the more it (muscle) is reduced during systole.
In short, the reflex of Bainbridge was the point of intersection of the different views, and today many of the knights, defending or denying the existence of this reflex, break a lance and mostly useless spoil it is a relic weapon.
The reader first meets these contradictions. We can even admit that the whole book is devoted to these contradictions. What is their solution (at least, what we see them a clue), as long as keep silent. Until the time comes. But agree that evolution has received at least strange, having arranged for circulation such regulation, which can all of a sudden work in the opposite direction. Go you on a level highway and to add speed, stronger push on the gas pedal and the car slows down the movement. You want to turn right, turn the wheel to the right, and the car is all right and then a left turn. Sudden obstacle, you squeeze grip and push on the brake, and machine speeds. Is it good? However, with the evolution will not argue the fact is, "that at least sometimes the mechanisms that she designed and perfected many millions of years, work as expected. Then it should be.
Now, hopefully, the reader is well prepared, so that we could solemnly to enter it in the main part of this book.
