An enlarged picture of Kidney has the following parts labeled:

1. Renal cortex
2. Renal medulla
3. Nephron
4. Ureter
5. Renal vein
6. Renal artery

The entry of waste-laden blood into the kidneys through the renal artery is indicated by an arrow pointing towards the renal artery. The filtered blood leaving the kidney through the renal vein is indicated by an arrow pointing outward. The connection of ureter to the bladder is indicated by a downward arrow. The parts labeled in the picture of nephron are:

1. Bowman’s capsule
2. Glomerulus
3. Artery
4. Vein
5. Loop of Henle
6. Capillaries
7. Tubule
8. Collecting duct

The collecting duct passes the fluid to the ureter which is indicated by a downward arrow. The text box captioned filtration on the right reads ‘Blood enters a nephron through a capillary from the glomerulus, filtrate flows into a tubule. Blood cells and large substances remain in the capillary.’ Below it, the text box captioned reabsorption reads ‘As the filtrate moves through the tubule, water and many other substances that are important to the body are reabsorbed through into the blood.’ Below it, the text box captioned urine excretion reads ‘Once water and other important substances are reclaimed by the blood, the filtrate is called urine. Collecting ducts gather urine and transport it to a ureter.’
