Which of the following is a function of the liver?

1. Production of hormones

2. Detoxification of substances

3. Storage of glucose

4. All of the above

The correct answer is: All of the above

The liver performs a multitude of essential functions that are critical for maintaining metabolic homeostasis in the body. Among these functions are the detoxification of harmful substances, the storage of glucose, and the production of various hormones. The detoxification process is vital because the liver helps break down and remove toxic substances from the bloodstream, including drugs and alcohol. This function protects the body from potential damage and maintains overall health. Additionally, the liver is key in regulating blood glucose levels. It stores glucose in the form of glycogen and releases it into the bloodstream as needed to ensure a stable supply of energy for the body's cells. Moreover, the liver is involved in the production of hormones, such as insulin-like growth factors and angiotensinogen, both of which have significant roles in various physiological processes, including growth and blood pressure regulation. Considering these multiple critical functions, it is clear that the liver is integral not only to detoxification and glucose metabolism, but also to hormone production. Thus, stating that all of these functions are associated with the liver accurately reflects its essential role in the body.
