The urinary system is like a city's water treatment plant that assures its residents of a continual supply of fresh, pure water.
Our urinary system passes water within the blood through a filtration process so the body can maintain a clean supply of fluids. This system is also responsible for maintaining the important sodium-potassium balance of minerals in and around our cells necessary for a high level of healthy energy. The kidney, bladder, ureters, and urethra comprise the urinary system.
The kidneys are paired, bean-shaped organs, each weighing about five ounces and buried in fat. The kidneys together contain approximately 2.4 million nephrons or filters. Stretched out end to end, these filters would be 50 miles long.
The kidneys excrete either an acid or alkaline urine that helps maintain the proper acid/alkaline balance of body fluids.
The ureters connect the kidneys and bladder The bladder is shaped like a pear when empty and becomes oval as it fills with urine. It can hold an average of one pint of urine.
The kidneys regulate the amount of water, acids, and salts in the body and ensure that the body doesn?t poison itself. Water, salt, minerals, glucose, urea (waste from protein breakdown), and creatinine (waste from muscle metabolism) form the filtrate that passes from the nephrons to the kidney tubules, where most of the water, salts, and glucose are reabsorbed. About 300 pints of water are filtered in the kidneys each day, but only about two and a half pints are excreted in urine. More than 99 percent of the water is reabsorbed. When there is too much fluid in the body, the kidneys excrete more water; when there is not enough, they conserve water. Regulation of water excretion also helps regulate blood pressure, since blood is 50 percent water.
Ninety-six percent of urine is water, a transport medium to keep the 4 percent of dissolved solids in solution. Occasionally, dissolved salts may fall out of solution and solidify to form deposits.
Potassium and sodium are crucial to the body's fluid balance. More than half of the water in the body is inside the cells. The rest is mixed with salt?rather like diluted sea water?and bathes the cells.
To maintain healthy cells, the proper concentration of salts is needed. For example, when blood cells are placed in tap water, they swell and burst, since water is rushing into the cells by osmosis. When placed in a 5 percent salt solution, the cells shrink and wrinkle up, since water is rushing out.
The kidneys are the major regulating mechanism for maintaining proper sodium and potassium balance. They are designed to excrete extra potassium and save sodium, since there is plenty of potassium in foods, but not as much sodium. However, people are now eating more sodium foods (mainly processed foods with added sodium) and not as many fresh foods with natural potassium.
Even with a high-sodium diet, the kidneys still save sodium and excrete potassium. We can?t change the way our kidneys function, but we can change our diet. Since food processing lowers the potassium content of foods, we should eat plenty of fresh foods.
Herbal food supplements, vitamins, and minerals can also help provide the urinary system with the nutrients it needs to effectively perform its delicate chemical balancing act.
Often taken for granted, the kidneys are constantly serving to purify the blood, balance the body's fluid and maintain the correct ratio of sodium/potassium and glucose required for energy. Such a job description necessitates adequate rest, nutrition and added supplementation to help the body deal with the stress of our modern environment.

|The best way to get the potassium you need without the extra sodium is to eat more unprocessed, natural foods. For example, use raisins on your breakfast cereal instead of honey or sugar. For a mid-morning snack, eat a banana or peach instead of pastries. Also, have grapefruit juice instead of a soft drink.|
Vitamin A was the
first vitamin to be discovered. It has been shown to be essential in
maintaining good vision and promoting normal growth. It occurs in animal
tissues as retinol but in plants as carotene?a precursor of vitamin A. It
is necessary for the health of epithelial cells and the immune system. It
is also required for the digestion of protein. Extra amounts are stored in
the liver, but megadoses over time can be toxic. However, Beta-carotene,
as a natural plant source of vitamin A, poses no such risk. It is
essential for lactation, reproduction and the formation of steroid
hormones. It is used to form the cells lining the digestive, respiratory,
reproductive and urinary tracts and in all tissue linings of the body. It
is also vital for healthy skin and is a famous antioxidant. It is best
absorbed by the body when taken with oil or fat.
