What do kidneys do ? How can kidney disease be treated?

Bladder Artery to bladderVein from bladder

What do kidneys do ? Once waste is in the blood the body needs to get rid of it ASAP Kidneys sort the body’s waste products from the useful stuff that needs to be kept & recycled Blood flows in via an artery Blood flows out via a vein Waste goes to bladder via the ureter

What do kidneys do ? Blood with waste products “Clean” blood Waste (urine) to the bladder

What’s in the blood coming into the kidney? Wasteuseful Protein Urea Sugar (glucose) ions water

How does the kidney sort out the waste? Blood in (Contains useful and waste materials) Blood out (useful stuff only) Urine to the bladder (waste only)

How does the kidney sort out the waste? Blood in (Contains useful and waste materials) Blood out (useful stuff only) Urine to the bladder (waste only) Protein Glucose  Ions  Water  Urea Glucose  Ions  Water  Ions  Water  Urea

How does the kidney sort out the waste? 1. Blood is filtered

How does the kidney sort out the waste? Blood is filtered Q. Use information from the diagram to explain why protein is not found in the urine of a healthy person (1 mark)

How does the kidney sort out the waste? Kidney tubule (filtrate) now contains Protein Glucose  Ions  Water  Urea Urine to the bladder (waste only)  Urea

How does the kidney sort out the waste? 2. Kidney tubule (filtrate) now contains Protein Glucose  Ions  Water  Urea Urine to the bladder (waste only)  Urea

How does the kidney sort out the waste? 2. Network of capillaries surrounding kidney tubule reabsorb Glucose * Ions * (if needed) Water (if needed) Urine to the bladder (waste only)  Urea  Ions (if not needed)  Water (if not needed)

Explain why urine in our bladder contains urea but does not contain protein or glucose 5 marks

After filtration all the glucose is Releasedrespiredreabsorbed (1 mark)
