Next to liver, kidneys are also of great significance to the maintenance of bodily health. The main and important function of the kidneys is to remove or eliminate a greater part of refuse and waste matter that piles up in the system during the bodily activities.
The kidneys are two and are bean-shaped organs situated in the back part of the abdominal cavity. They are on either side of the spine lying above and below the waist-line. From the central part of each kidney, a tube originates and terminates in the bladder.
These two tubes are called ‘Ureters’ and they serve to convey urine from the kidneys to the bladder.
The interior of the kidneys has a complicated system, which performs the function of a filter to purify blood. In the filtration of the plasma, the usable part of blood is returned to the heart through the renal vein, while the waste matter is eliminated through the bladder.
As the usable part of blood, amino-acids—glucose, sodium, potassium, calcium, magnesium and chlorine—is absorbed into the system, the wastes, like urea, uric acid and phosphates, etc. are ejected through the urine via the bladder.
The cause of kidney ailments, like the congestion of the kidneys (or renal hypermania), etc. is the gradual accumulation of poisons from acidic foods and chemical drugs, which cause congestion in the kidneys, ultimately obstructing the flow of blood through the tiny capillaries of the kidneys.
The symptoms of the congestion of the kidneys are a constant desire to pass water and a high density and deep colour of the urine.
The course of treatment is almost similar to the one suggested in the treatment of liver.
