The excretory system, responsible for removing various waste products from the body, includes which of the following organs?

AOnly the stomach and small intestine
BOnly the brain and spinal cord
CThe kidneys, skin, lungs, and liver, among other organs
DOnly the heart and lungs

Explanation

The excretory system, broadly responsible for removing various metabolic waste products from the body, includes several different organs working together, notably the kidneys, which filter waste from the blood to form urine, the skin, which eliminates some waste through sweat, the lungs, which remove carbon dioxide through exhaled breath, and the liver, which processes certain waste products before they are eliminated by other means. Each of these organs plays a distinct but complementary role in helping maintain the body’s overall internal chemical balance by removing substances that could otherwise become harmful if allowed to accumulate. Proper functioning of this interconnected system is essential for maintaining overall health and preventing the buildup of potentially toxic waste products within the body.
