All rights reserved. The kidneys are a pair of organs located in the back of the abdomen. Each kidney is about 4 or 5 inches long -- about the size of a fist. The kidneys' function are to filter the blood. All the blood in our bodies passes through the kidneys several times a day. The kidneys remove wastes, control the body's fluid balance, and regulate the balance of electrolytes. As the kidneys filter blood, they create urine, which collects in the kidneys' pelvis -- funnel-shaped structures that drain down tubes called ureters to the bladder. Each kidney contains around a million units called nephrons, each of which is a microscopic filter for blood.
Kidneys and Protein. Kidneys are bean-shaped organs in your lower back -- one is on your right side and one is on your left. Nephrons are structures inside each kidney that contain tiny tubes called glomeruli. These glomeruli are responsible for filtering your blood to remove waste products and fluid to produce urine. Kidney damage allows protein to pass through the glomeruli and move into your urine.
