What is the role of the liver in human physiology?

• A. Regulating blood pressure
• B. Detoxifying chemicals
• C. Transporting oxygen
• D. Producing hormones

Answer: (B)

The liver plays a crucial role in human physiology, particularly in its ability to detoxify chemicals. It acts as a filter for the blood, processing substances that enter the body through absorption and digestion. One of its primary functions is to metabolize drugs and alcohol, converting them into less harmful compounds that can be excreted. The liver also processes byproducts from the metabolism of nutrients and plays a vital role in eliminating toxins from the bloodstream, making it essential for maintaining overall health and homeostasis. This detoxification function highlights the liver's importance in protecting the body from potentially harmful substances that can arise from various environmental and dietary sources.
