Which organs assist in breaking down the remaining 10% of alcohol in the system?

The correct answer highlights the roles of the kidneys, skin, and lungs in the process of excreting alcohol from the body. While a significant portion of alcohol is metabolized by the liver (approximately 90%), the remaining small percentage, around 10%, is eliminated through other means.

The kidneys play a vital role in filtering blood and excreting waste products, including some alcohol, in the urine. The skin also contributes through perspiration, where small amounts of alcohol can be excreted. Additionally, the lungs are involved in eliminating alcohol through exhalation; this is why breathalyzers are effective in measuring blood alcohol content.

This option accurately reflects the physiological processes that facilitate the elimination of alcohol outside the liver's primary metabolic responsibilities. The other options do not encompass the correct organs in the context of alcohol excretion, as they either include organs less involved in the elimination process or exclude the essential organs responsible for this specific function.
