Many organs are involved in the processes of keeping the blood and the body clean. when poisonous or harmful substances are in the blood, they are absorbed by the and released in a less harmful form. when wastes are present in the blood, they are filtered out and removed from the body by the

The answer is; Liver, kidney

The liver is a significant organ of detoxification of the body. The xenobiotic biotransforming enzymes in the liver breakdown and oxidize/ reduce and hydrolyze toxins and make them less effective. The specificity of these enzymes is broad thence are able to break down a wide variety of toxins we are normally exposed to in our environment.

When the liver break down the toxin to less harmful metabolites, these molecules are filtered out by the kidney and excreted outside the body with urine.

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
