CLEAR PROOF OF CREATION: KIDNEYS THAT DISTINGUISH BETWEEN GLUCOS

CLEAR PROOF OF CREATION: KIDNEYS THAT DISTINGUISH BETWEEN GLUCOSE, PROTEIN AND SODIUM Throughout your life, your two kidneys cleanse the blood flowing throughout your body. Some of the material that they filter out is sent back to the body, while the rest, of no further use, is discarded into the bladder. But how do the kidneys distinguish between protein, urea, sodium, glucose and many other substances? The structure that filters waste products from the blood is a cluster of capillaries, called the glomerulus. Unlike capillaries in other parts of the body, these are surrounded by a membrane composed of three layers. And with great meticulousness, these three layers decide which substances will be filtered and excreted, and which will be retained and sent back to the body. Now, on what basis—and with which mechanism—does a cell membrane analyze, one by one, substances coming through the bloodstream and decide where they need to go? In any liter of blood, there are dozens of dissolved compounds that reach the kidneys, including glucose, bicarbonate, sodium, chlorine, urea, and creatine. The kidneys excrete from the body some of these substances entirely, remove only parts of some others, and still others they return to the bloodstream in their entirety. But how does a piece of tissue decide which substances to discard, and how much? The answer lies in the fact that kidney tissue has been created with a perfect plan. The glomeruli's selectivity is determined by the electric charge and size of the molecules it detects in the blood. This means that the glomeruli have the ability to determine the molecular weight of the sodium and glucose and the negative charge of the proteins all mixed up in the blood. In this way, proteins vital to the body are not discarded, but retained for further use.  But the glomerulus is made up of capillaries only. How do you suppose that a structure can possess such superior discrimination, even though it's never been educated in chemistry, physics or biology? The glomeruli can carry out such functions faultlessly because they act through the inspiration given to them by the One Who created them—that is, God. Under no circumstances is their selection of substances left to chance. If it were, by the time these unconscious organs located the correct molecules, our bodies could no longer function. All of this is just one proof of the perfect creation of God.
