Kidneys are shaped like small beans, which are no bigger than your fist. They are located on either side of our backbone under the ribcage.
The diagram illustrates how the kidneys are constructed. First, the blood comes into the kidney through the renal artery and leaves in the renal vein, traveling on the same flow as blood that goes in and out of the heart.
Filtering the blood is the responsibility of about one million nephrons located in each kidney. These serve as the primary tool behind your kidney function. Nephrons use a glomerulus and a tubule to conduct the filtering process. What this system determines as waste gets flushed out of the kidneys in the form of urine along with extra water that the body does not need. Waste products are produced from food and fluid intake as well as normal tissue breakdown after the body has used what it needs for nutritional balance, energy, and self-repair. This process of food and tissue breakdown is known as your metabolism.
The urine travels through tubes called ureters into the bladder. It is here in the bladder where urine is stored until it is excreted out when you go to the bathroom. Normal kidney function produces one liter of urine from approximately 1,000 liters of blood that is processed by these two tiny organs.
