What Are Kidneys?

Kidneys are organs in a shape of a bean. Their size can be compared with the size of your fist. They are situated below the rib cage in the middle of your back on each side of your spine. Kidneys are cinsidered to be trash collectors, as they process much blood and sift waste products with extra water. These sifted elements become urine and flow to youк bladder through ureters, and your bladder stores and accumulates urine and sends signals to your brain when it is time to go to the bathroom.

More than half ofkidney stonesformed by adults are calciumoxalate. Due to some recent research after taking dietaryoxalate, only 15% of it is found in the urine of those who form calciumoxalatestones, that's why it is widely believed that diet can't prevent stone formation. However, those foods, that were thought to form stones due to theiroxalatecontent appear to have preventive effects. For these reasons healthcare professionals recommend to restrict dietary oxalates that will prevent calciumoxalatestone formation.
