"Excretion is a process to eliminate the waste by-products from the body". Justify the statement.
Dear student,
Excretion is the process by which waste materials that is produced inside the body comes out. Body carries the impurities that are filtered inside our kidneys. Kidneys filter out the waste matters and again release the pure blood in the body. The waste matters mixed with excess water forms urine. After formation the urine gets stored inside the urinary bladder. When the bladder gets filled a pressure is created by the walls of bladed which helps the urine to flow into the ureter and comes out of the body through urethra.
