In addition to detoxification, what is another major function of the liver?

• A. Regulation of body temperature
• B. Production of bile for fat digestion
• C. Storage of white blood cells
• D. Secretion of neurotransmitters

Answer: (B)

The liver plays a crucial role in digestion, particularly in the production of bile, which is essential for the emulsification and digestion of fats. Bile is composed of bile acids, cholesterol, and bilirubin, and it is stored in the gallbladder until it is needed for digestion. When you eat a meal that contains fat, bile is released into the small intestine, where it helps break down the fats into smaller droplets, making them easier for digestive enzymes to work on and thus facilitating their absorption into the body. This function is vital for proper nutrient absorption and overall digestive health.

The other options represent functions that are not primarily associated with the liver. For example, body temperature regulation is largely managed by the hypothalamus and skin, the storage of white blood cells occurs mainly in lymphoid tissues and the spleen, and neurotransmitter secretion is primarily related to the nervous system, particularly in the brain and nervous tissue.
