The gall is on the right side of the body below the ribs. The gallbladder is located in the right upper abdomen at the lower edge of the ribs and is a pear-shaped sac structure behind the liver. The gallbladder has the function of concentrating and storing bile, but does not secrete bile, which is secreted by the liver. The gallbladder is divided into four parts: the base, the body, the neck and the duct, the neck is connected to the cystic duct, and the wall of the gallbladder consists of three layers: the mucous membrane, the muscularis propria and the plasma membrane. Gallbladder mucosal epithelium lined by high columnar epithelial cells, the mucosa has many wrinkles, wrinkles between the mucosal epithelium deep into the lamina propria and even the muscularis propria, the formation of many sinusoidal depressions, known as the Aschoff sinus, in which inflammation or the formation of stones are prone to occur. The submucosal layer is rich in capillaries; between the muscular layer and the plasma membrane layer there is a thick layer of connective tissue, rich in lymphatic vessels, small blood vessels and intrinsic plexus. It is recommended that patients with gallbladder discomfort go to a regular hospital, do not blindly deal with it on your own to avoid delaying the condition.
