I'm current revising for my GCSEs and have a question about the Kidneys it reads: Describe how a healthy kidney produces urine. I know everything but I can never remember the kidneys. Please help me.

The kidneys are part of the urinary system, together with the ureter, urethra and bladder. Humans have two kidneys. They are bean-shaped organs - approximately 11.5 cm long – which are found just below our ribcage, one on either side of our spine.Location of kidneys in abdominal cavitylocation of kidneys in abdominal cavityThe renal arteries take blood with waste products to the kidneys to be filtered. Renal veins then return the filtered blood to be circulated around the body.Blood vessels take the blood though the kidneys where the waste products are removed into convoluted tubules. These tubules join together to form the ureter, which transports urine to the bladder where it is stored. Urine is then passed from the bladder to the urethra to be released.

this is what i have to learn for my wjec board, the kidney is a filtering system where urea, salt, glucose, protein, water pass through but only urea, some salt, some water should pass through if the kidney is healthy. There is the filter in the kidney called the nephron. it filters by ultrafiltration (filter under pressure). there's the bowman's capsule and all sort of loops, the blood enters the renal artery to get into the kidney and this goes to the nephron and the filtered solution (urine) pass out to the ureter which leads to the bladder and then out of the urethra.
not sure if your board require the same or different kind of details.

I do AQA and i'm a current year 11 student.

The Kidneys:
1) Filter the blood (Urea, glucose, water, minerals and ions)

2) Reabsorbs ALL the glucose originally filtered out the blood.
3) Reabsorbs the water required to maintain constant water level.
4) Reabsorbs the minerals and ions required to maintain a constant level.

(This is all called selective reabsorption)

5) All excess minerals and ions (molecules which have not been selectively reabsorbed) as well as urea forms urine which passes down into the bladder.
