Male Gallbladder Section

Description

A cross section of the male gallbladder, cut to expose the internal mucosal surface and layered wall structure. The mucosa shows the extensive folding pattern (rugae) that increases surface area for water absorption during bile concentration. The muscular wall and serosal covering are visible at the cut edge. Bile enters the gallbladder in a dilute form from the liver and is concentrated up to tenfold as the mucosal epithelium absorbs water and electrolytes. The concentrated bile is stored until a fatty meal triggers cholecystokinin release and gallbladder contraction. The section supports hepatobiliary anatomy teaching and patient education.
