MICROANATOMY

Detailed explanation-1: -Hepatocytes (parenchymal cells) are the basic structural component of the liver, representing 60% of the total cell number and 80% of the total liver volume. They are arranged radially within the lobule to form cellular plates, between which the liver capillaries and the sinusoids are located.

Detailed explanation-2: -Abstract. The hepatic sinusoid harbors 4 different cells: endothelial cells (100, 101), Kupffer cells (96, 102, 103), fat-storing cells (34, 51, 93), and pit cells (14, 107, 108). Each cell type has its own specific morphology and functions, and no transitional stages exist between the cells.

Detailed explanation-3: -The human adult liver weighs approximately 1.4–1.7 kg, with a hepatocyte density of 1.1–1.6 × 108 cells /g [6], and has an estimated number of 2 × 1011 or 200 billion hepatocytes.
