The renal/urinary system removes Blank 1 Question 49 products from the body and maintains fluid and Blank 2 Question 49 balance. The kidneys sieve the Blank 3 Question 49 (almost 200 litres per day) to filter waste products and regulate fluid and salt. The kidneys also produce a hormone that assists in controlling blood Blank 4 Question 49 . Urine, containing these waste products, is passed into the bladder through the Blank 5 Question 49 . The urine is then expelled from the body through the urethra.
The kidneys help Blank 6 Question 49 fluid balance by altering how much water is retained or excreted. If there is insufficient water in the body, urine production will be Blank 7 Question 49 . If there is a large amount of water in the body, urine production will Blank 8 Question 49 .
The main Blank 9 Question 49 are sodium, potassium, calcium, phosphorus and magnesium. The kidneys detect the volume of these. If an electrolyte is too high, the kidneys will increase excretion or retain fluid to keep it in Blank 10 Question 49 .
Along with the lungs and brain, the kidneys keep blood Blank 11 Question 49 levels within an ideal range. Cells produce carbon-dioxide and other acids as waste. They release this into the blood stream making the blood more acidic. Some carbon-dioxide is removed by the lungs (when we breathe out) and the kidneys filter acid from the blood. Metabolic Blank 12 Question 49 occurs when the kidneys cannot control the acid levels.
