Excretory System Exercise 97
Solution 2
Carbon dioxide (CO2) and urine
Solution 5
Solution 3
Ammonia is toxic in even small amounts and therefore it must be removed from the body. The urea cycle or the orinithin cycle, in the liver, involves the conversion of ammonia into urea. Then the urea is then transported to the kidneys where it is excreted.
Solution 4
Nephron is the basic structural and functional unit of the kidney.
Its chief function is to regulate the concentration of water and soluble substances like sodium salts by filtering the blood, reabsorbing what is needed and excreting the rest as urine.

Solution 1
Separation and elimination of the metabolic nitrogenous wastes from the body is called excretion.
Kidneys, skin and lungs are important excretory organs.
