Question

the liver, large intestine, skin, lungs, and kidneys are apart of the ____ system. resiratory cardiovascular excretory

Explanation:

The excretory system is responsible for removing waste products from the body. The liver processes and eliminates toxins, the large intestine removes solid waste, the skin excretes sweat (containing waste), the lungs exhale carbon dioxide (a waste gas), and the kidneys filter and excrete urine (containing metabolic wastes). The respiratory system is mainly for gas exchange (lungs are part of it but not the other organs here), and the cardiovascular system is for transporting blood, not waste removal. So the correct option is the one related to waste elimination, which is excretory.

Answer:

C. excretory (assuming the options are labeled A, B, C as respiratory, cardiovascular, excretory respectively)
