I'm not exactly certain what you mean by 'carry away,' but in general the blood is what carries wastes from the site at which they are generated to a location where they can be dealt with. Cells produce wastes as they live and grow - this includes muscle cells, skin cells, brain cells - any cell in the body. As we use sugars for energy, carbon dioxide (CO2) is created. CO2 dissolves in the blood and is released in the lungs so we can exhale it. Other kinds of waste products are taken up by the liver and detoxified. Also, the kidneys endlessly filter the blood, removing wastes which end up in the urine.
