The Message Concealed in the Fibers of the Heart


Located in the depths of the fibers of the heart are special molecules carrying a very important message that concerns not the heart, but another organ far distant from it. Under normal conditions, however, the molecules carrying the message, can never leave that region, because they are surrounded by powerful heart fibers.
So, what message do these molecules carry? And why are they located in the depths of the heart tissue? As we examine the answer to these questions, another miracle of creation emerges.
This molecule is a hormone known as atrial natriuretic factor. Only the kidneys can decipher the message it contains, instructing them to expel sodium from the body. 46
Why is a message to be sent to the kidneys concealed within the depths of the heart? And what does the heart have to do with the kidneys expelling sodium from the body? However, Allah has created the human body with thousands of interconnected systems. The concealing a message of concern to the kidneys within the depths of the heart is just one of these complex, interconnected systems.
High blood pressure—a rise in the force exerted by fluid in the veins—is a very dangerous condition that can be fatal unless precautions are taken. Increasing blood pressure causes the heart to expand, opening gaps between the muscle fibers, and the message molecules imprisoned there are released into the bloodstream and then reach the kidneys. The kidney, obeying the instruction, acts to expel the sodium from the body. Blood pressure thus returns to normal levels, and the heart continues to beat healthily.
What Happens When Blood Pressure Falls?
The kidneys’ role in regulating blood pressure does not end there. When blood pressure is low, the kidneys secrete a substance called rennin from a cell with a special structure known as the JGA. Yet this substance has no direct pressure-reducing effect of its own.
This substance combines with a molecule called angiotensinogen, secreted by the liver, far distant from where it itself is produced, and transforms into the molecule angiotensin-1. Yet this resulting hormone has no serious effect on blood pressure. This hormone, present in the bloodstream, turns into a very different molecule: angiotensin-2, thanks to an enzyme called ACE which is present in the lung and serves only to break down the molecule angiotensin-1.47
This molecule, produced at the very end of the process, is the hormone that affects the veins and raises blood pressure back to normal levels. If that molecule did not exist, then none of the “earlier” hormones produced before it would have any effect on blood pressure. The molecule angiotensin-2 only contracts the veins after combining with sensors located on the surface of the vein and thus increases blood pressure.
The angiotensin-2 molecule does more than this to raise blood pressure. The bloodstream transmits the molecule to a gland above the kidneys. Certain cells in this region release into the blood a molecule called aldosterone, which these cells produce only after combining with angiotensin-2. When this happens, blood pressure begins to rise under the influence of another mechanism. By combining with the special receptors on the kidney’s collecting channels, the aldosterone molecule permits the body to re-absorb sodium molecules expelled in urine. 48 The sodium molecules then raise the blood pressure by increasing the density of the blood.
Without doubt, the effects of these substances are interconnected. Since not a single one of these could have come about by chance, it is even more impossible for all of this system’s components to have emerged by coincidence in the human body. Coincidences cannot give the kidneys their ability to understand, nor the necessary initiative to adopt various measures.
To claim that the order of the dozens of substances and mechanisms used to regulate blood pressure came about by themselves is a form of behavior unique to people blindly devoted to the theory of evolution, who have adopted it as a belief system. Indeed, evolutionists have admitted in various ways that theory is only a belief, and flies in the face of all the facts. One of these admissions reads as follows:
From my earliest training as a scientist, I was strongly brainwashed to believe that science cannot be consistent with any kind of deliberate creation. That notion has had to be painfully shed. At the moment, I can’t find any rational argument to knock down the view which argues for conversion to Allah. We used to have an open mind; now we realize that the only logical answer to life is creation—and not accidental random shuffling. 49
CAN YOUR KIDNEYS POSSESS MEDICAL INORMATION?
Your kidneys constantly measure the level of erythrocytes in the blood that’s pumped through them. The figures are immediately analyzed by the sensitive receptors and the necessary steps taken. 
In the event they detect any reduction  in the blood being filtered, special cells in the kidneys secrete a hormone known as erythropoietin. The hormone manifests its effect not in the kidneys, but in the bone marrow. This hormone notifies the bone marrow’s main blood-producing cells that the number of erythrocytes has declined, at which erythrocyte production is accelerated. More erythrocytes are released into the bloodstream, and the level of erythrocytes is thus kept balanced. But the kidney cells take the initiative to put the necessary steps into operation. Cells in the bone marrow decipher this hormone’s message sent from the kidneys and act accordingly.

In addition, these processes all take place in the same way in every one of the billions of humans on Earth.

In all these processes, the cells demonstrate a very clear intelligence, and the source of that intellect needs to be questioned. It’s impossible to claim that the cells arrived at that intellect by themselves or by chance. Allah installed that intelligence in the cells and inspired their behavior in them. There is no other power but Allah.
Clearly and irrefutably, all the scientific facts that evolutionists have had to admit show the existence of a Creator Who has dominion over everything—in other words, the existence of Allah.
