The kidneys
The kidneys are two bean-shaped organs about the same size as a fist. They are located near the middle of the back, one on either side of the spine. The kidneys are part of the body system called the urinary system. They filter the blood. As the blood passes through them, waste products and unneeded water are collected and turned into urine. This happens in tiny tubes called nephrons. Each kidney has about 1 million nephrons.
The urine drains into the bladder down a tube called the ureter. There are 2 ureters ??“ one from each kidney. Another tube called the urethra carries the urine from the bladder out of the body.
Hormones
The kidneys also produce three important hormones. Erythropoietin (EPO) tells the bone marrow to make red blood cells. Renin regulates blood pressure. Calcitriol (a form of Vitamin D) helps the intestine to absorb calcium from the diet.

Where the kidneys are
The kidneys are two bean-shaped organs about the same size as a fist. They are located near the middle of the back, one on either side of the spine.

What the kidneys do
The kidneys filter the blood. As the blood passes through the kidneys, waste products and unneeded water are collected and turned into urine.
The urine is gathered in an area called the renal pelvis at the centre of each kidney. From here it drains into the bladder down a tube called the ureter. There are 2 ureters – one from each kidney. Another tube called the urethra carries the urine from the bladder out of the body.
Inside the kidney, the blood is filtered through very small networks of tubes called nephrons. Each kidney has about 1 million nephrons. Inside the nephrons, waste products in the blood move across from the bloodstream (the capillaries) into the urine-carrying tubes inside the nephron. These tubes are called tubules. As the blood passes through the blood vessels of the nephron, all unwanted waste is taken away. Any chemicals needed by the body are kept or returned to the bloodstream by the nephrons. In this way, the kidneys help to regulate the levels of chemicals in the blood such as sodium and potassium, and keep the body healthy.

Hormones from the kidneys
As well as filtering waste products, the kidneys produce three important hormones
* Erythropoietin (EPO) tells the bone marrow to make red blood cells
* Renin regulates blood pressure
* Calcitriol (a form of Vitamin D) helps the intestine to absorb calcium from the diet, and so helps to keep the bones healthy

The kidneys??™ blood supply
The kidneys have a very rich blood supply. The blood needs to pass through in large quantities so that it can be filtered well, and all the waste products can be removed. The main blood supply carrying blood to each kidney is called the renal artery.
There are also large blood vessels carrying the cleaned blood away from each kidney. These are called the renal veins

There are two kidneys, one on each side of the spinal column. They are approximately 11cm long, 5-6cm wide, and 3-4cm thick. They are said to be bean-shaped organs where the outer border is convex; the inner border is known as the hilum and it is from here the renal arteries, renal veins, nerves and the ureters enter and leaves the kidneys.
Function of the kidneys is to make urine by filtering blood.
