Which of the following is NOT a function of the liver?

The liver plays a vital role in numerous bodily functions, including bile production, detoxification, and phagocytosis. Bile production is essential for fat digestion and absorption in the intestines. Detoxification in the liver involves the breaking down and removal of harmful substances from the bloodstream, such as drugs and toxins. Phagocytosis in the liver is mainly carried out by Kupffer cells, which help to remove pathogens and debris from the blood.

Sunlight absorption, however, is not a function of the liver. This process typically occurs in the skin, where UV radiation from sunlight is absorbed and converted into vitamin D. Therefore, the correct answer indicates that sunlight absorption is not a function of the liver, distinguishing it from the other listed functions that the liver performs.
