Liver architecture refers to the organized structure of the liver, which is crucial for its multifaceted functions including metabolism, detoxification, and synthesis of vital proteins. The liver is composed of hexagonal lobules, each containing hepatocytes arranged around a central vein, with a portal triad at each corner facilitating blood flow and bile transport.

Metabolism is the set of life-sustaining chemical reactions in organisms that enable them to grow, reproduce, maintain their structures, and respond to environmental changes. It involves two main processes: catabolism, which breaks down molecules to produce energy, and anabolism, which uses energy to construct components of cells such as proteins and nucleic acids.

metabolism

Detoxification is the physiological or medicinal removal of toxic substances from a living organism, primarily carried out by the liver. While it is a natural process, various detox diets and regimens claim to enhance the body's ability to eliminate toxins, though scientific evidence supporting these claims is limited.

Hepatocytes are the main functional cells of the liver, responsible for a wide range of metabolic, detoxification, and synthetic activities crucial for maintaining homeostasis. These cells play a central role in processing nutrients, producing bile, and detoxifying harmful substances, making them essential for overall liver function and systemic health.

hepatocytes

The central vein is a crucial component of the liver's lobular architecture, responsible for collecting blood from the liver sinusoids and directing it towards the hepatic vein. It plays a vital role in the liver's blood filtration and detoxification processes, ensuring the efficient removal of toxins and metabolic byproducts from the bloodstream.

central vein

The portal triad is a distinctive anatomical feature of the liver, consisting of three essential structures: the hepatic artery, portal vein, and bile duct, all enclosed within a connective tissue sheath. This triad is crucial for the liver's dual blood supply, facilitating the delivery of oxygenated blood and nutrients while also managing bile production and secretion.

portal triad

Blood flow refers to the movement of blood through the circulatory system, driven by the heart's pumping action and regulated by blood vessel constriction and dilation. It is essential for delivering oxygen and nutrients to tissues and organs while removing waste products, maintaining homeostasis and supporting overall health.
