The primary functions of the liver encompass a wide range of critical metabolic processes. One of its most crucial roles is detoxification of blood, which involves the breakdown and removal of harmful substances, toxins, and metabolic waste products. This function is vital for maintaining overall health and preventing the accumulation of potentially damaging compounds in the bloodstream.

Additionally, while the liver does participate in lipid metabolism and protein synthesis, these functions are secondary to its role in detoxification. The liver metabolizes fats and proteins, converting them into usable energy or storage forms, but the detoxification process is more essential to its overall function. Furthermore, the liver does not produce insulin; rather, insulin is produced by the pancreas. Thus, understanding the liver's multifaceted roles helps clarify why detoxification stands out as one of its primary functions.
