Final Answer:
The liver performs three fundamental categories of vital functions: metabolic regulation, synthesis of proteins, and detoxification.
Step-by-step explanation:
The liver is a crucial organ with diverse functions essential for maintaining homeostasis in the body. Firstly, it plays a vital role in metabolic regulation, including glucose and lipid metabolism. The liver helps regulate blood glucose levels by storing or releasing glucose as needed. Additionally, it participates in the synthesis of proteins, including clotting factors and albumin. These proteins are crucial for various physiological processes, such as blood clotting and maintaining osmotic balance. Lastly, the liver is involved in detoxification, breaking down and eliminating toxins from the bloodstream. Hepatocytes, the liver cells, contribute to these functions, highlighting the organ's importance in overall health and well-being.
