Kidneys What is the function of the Kidneys
Kidney is one of a pair of organs located at the back of the abdomen, against the strong muscles next to the spine, and behind the intestines and other organs.
The adrenal glands lie on top of the kidneys.
Each kidney weighs about 5 ounces (140g) and is about 4 inches (10cm) long in the average adult.
Its inner structure, which is called the renal pelvis, collects urine as it is formed and passes it out of the kidney to the bladder via the ureter.
The renal pelvis also is connected to the artery and vein that carry blood to and from the kidney.
What is the function of the Kidneys?
The kidneys filter out water and also unwanted substances in the blood.These substances are produced by the normal working of the body.
They are excreted by the kidneys in the form of urine.
The kidneys also keep the salts and water of the body in correct balance.
How do kidneys work?
The blood passes through each kidney under high pressure.The blood is filtered by the glomeruli, special structures in the kidney containing clusters of capillaries that collect water, salts, and unwanted substances.
The filtrate passes along a fine tube, the nephron (of which there are approximately one million in each kidney), which reabsorbs any of the water, glucose, and salts that the body still re-quires and allows the rest to pass into the pelvis of the kidney as urine.

What is the Volume of Your Lungs
What youll need:
- Clean plastic tubing
- A large plastic bottle
- Water
- Kitchen sink or large water basin
Instructions:
- Make sure the plastic tubing is clean
- Put about 10cm of water into your kitchen sink.
- Fill the plastic bottle right to the top with water.
- Put your hand over the top of the bottle to stop water escaping when you turn it upside down.
- Turn the bottle upside down. Place the top of the bottle under the water in the sink before removing your hand.
- Push one end of the plastic tube into the bottle.
- Take a big breath in.
- Breathe out as much air as you can through the tube.
- Measure the volume of air your lungs had in them.
- Make sure you clean up the area to finish.
Whats happening?
As you breathe out through the tube, the air from your lungs takes the place of the water in the bottle. If you made sure you took a big breath in and breathed out fully then the resulting volume of water you pushed out is equivalent to how much air your lungs can hold. Having a big air capacity in your lungs means you can distribute oxygen around your body at a faster rate. The air capacity of lungs (or VO2 max) increases naturally as children grow up but can also be increased with regular exercise.
