Understanding the Liver: Functions and Importance

The liver, weighing about 1.4 kg, is a vital organ functioning as a storehouse, manufacturing hub, and processing plant. It filters blood from the hepatic artery and portal vein, processing nutrients and storing excess for future use. The liver detoxifies harmful substances, converting them for excretion. It manufactures proteins, cholesterol, vitamin D, and bile, which aids digestion and toxin removal. Maintaining liver health is crucial as it performs essential tasks that support bodily functions.
