The kidneys are two flattened, solid organs, whose shape resembles peas. Kidneys are the most important organs of our body. Long are about 8 inches and lie on either side of the spine at the level of the belt.
The kidneys expel unnecessary substances from the body. For the body is just as important to get rid of what is not necessary and what can not be used as it is important to bring what it needs. The kidneys regulate the amount of water and other substances in the blood.
In the outer part of each kidney blood capillaries are formed in the shape of a small loop clusters that is covered with a fine membrane. In each kidney has about 1.5 million of these clusters which are called glomerules. Each minute through the kidneys pass more blood than through any other organ. Glomerules passed through its skins a portion of fluid from the blood that carries the finest dissolved substances.
The fluid passing through the membrane is called the original urine. It is collected in goblet wall covering each glomerulus. Very fine tube, called tubules, drains urine from the goblet.
While urine flows through tiny tubules, in border stations of their wall is carried out exchange of substances. Substances necessary restores the blood. Therefore, the sugar is lost from the body.
A large part of the water from tube is also returned to the blood. In this way the kidneys ensure sufficient quantities of water. If someone is sweating or not drinking enough water, the kidneys will return more fluid in blood. In this case will make less urine. Kidney tubes also allow regulation of blood acidity.
