LIVER

Histology of Liver

• Made up of hexagonal areas – hepatic lobules.
• Each separated – connective tissue septa.
• Each lobule has cords of liver cells separated by sinusoids.
• Each liver cell is
  • - one cell thick
  • - anatomizing with one another forming a network
  • - spaces between the liver cells is sinusoids
• Along the periphery of each lobule there an area filled with connective tissue.
• This area is called the portal canals.
• Portal canals has
  • 1. branch of portal vein
  • 2. branch of hepatic artery
  • 3. interlobular bile duct
  • knowns as PORTAL TRIAD
• Blood from the portal vein, hepatic artery enter the sinusoids at the periphery of the lobule.
• The blood flows towards the centre and open into a vein in the middle called central vein .
• Central veins drains into the hepatic vein – IVC
