Which organ system removes waste products from blood?

D) Excretory System.

It is because of the kidneys which do the work in removing waste.

So when it breaks down nutrients into waste that is usually transfered

into urea.

Just message me if you want more info! :)

I'm currently learning about the excretory system too ,

Don't worry, all the human body systems are pretty easy to understand !

Its a trick question: The malphigian tubules, is the old name for the proximal and distal convoluted tubules in the kidney (they didnt write kidney as an option, because is also the obvious correct answer)--- so, being the kidney with its convoluted descending and ascending malpighian tubules, responsible for cleansing the blood of excretory end products, and metabolic by products, IS the proper answer... letter "E"..

Technically none of the above, its actually the circulatory system, it gets rid of the carbon dioxide from your blood.
