2) And it also transports allthe carbon . dioxide and other waste products of the cells to the lungs to be expired or to the kidneys to be excreted.
3) The excretery system is closely related to the circulatory system by virtue of the process of cleaning the blood of waste, removing excess fluids and generally keeping other fluids in balance.
