The Kidneys and the Pressure in the Veins

One of the kidneys’ important functions is regulating blood pressure, determined mainly by the level of fluid in the veins.

The more fluid in the veins, the higher the rise in blood pressure, which can damage many organs in the body.

Sensors on the anterior chambers of the heart perceive there is too much fluid in the veins. When the heart contracts with excessive fluid entering it, these sensors send a report of the situation to the brain, which then increases blood filtration by adjusting the width of the veins leading to the kidney.

Let us now consider an imaginary example of the pressure measurement carried out in the anterior chamber of the heart and the adjustments in the body performed in the light of it. Imagine a room, totally isolated from the outside world. A human being lives in there, and must spend his entire life in there—to fulfill a very important responsibility.

The air pressure on the walls of this room changes constantly. This man’s task is to measure that pressure with special equipment. He must also notify the measurements he makes to an information-processing center, making thousands of reports every day, and there must be no errors in any of them. If he forgets to take a measurement, grows inattentive, or makes an inaccurate measurement, then the room he lives in, the building that contains that room, and the city it stands in will all be destroyed!

One cannot even imagine a person devoting his life to measuring the pressure on the chamber walls, never sleeping for a moment, and never making a mistake. Yet the events that take place in the body far exceed the bounds of this example. Cells in the walls of the heart’s anterior chamber do indeed devote their entire lives to measuring the blood pressure and reporting the results to the brain. The fact that these cells perform such an important function with such self sacrifice all their lives, are located in the anterior chamber of the heart, can take measurements and inform the brain of these, all shows that these cells were specially created.
