The Liver in 3D

The largest gland in the body — it secretes bile, stores glycogen, and detoxifies the blood. Rotate it, zoom in, and tap each labelled part to learn its structure and function the NCERT way.

Parts of the liver

Right lobe

The larger of the two main lobes of the liver.

Left lobe

The smaller lobe, crossing towards the midline.

Hepatic portal vein

Brings nutrient-rich blood from the intestine to the liver.

Liver — the NCERT essentials

NCERT — Digestion and Absorption. The liver is the largest gland in the human body. Its cells (hepatocytes) secrete bile, which is stored and concentrated in the gall bladder and released into the duodenum.

Bile contains bile pigments (bilirubin) and bile salts but no digestive enzymes. Bile salts emulsify fats — breaking large fat droplets into smaller ones so that enzymes can act on them more easily.

The liver also stores excess glucose as glycogen, carries out deamination of amino acids, forms urea, and detoxifies harmful substances in the blood.

Did you know? It is the only human organ that can regenerate from a fraction of itself.

How the liver works — step by step

  1. 1

    Nutrient-rich blood from the intestine reaches the liver via the hepatic portal vein.

  2. 2

    Hepatocytes process the nutrients — storing glucose as glycogen and handling amino acids.

  3. 3

    The liver continuously secretes bile, which passes to the gall bladder for storage.

  4. 4

    On a fatty meal, bile is released into the duodenum to emulsify fats for digestion.
