Many people want to know about the normal size of the gallbladder, because the gallbladder is particularly important to one's physical health. Therefore, many people, in order to protect their own health, want to understand the specific relationship between the normal size of the gallbladder and health. In order for you to have a comprehensive understanding, let's take a look at the detailed introduction below. The gallbladder is located under the liver. A normal gallbladder is about 8 to 12 cm long, 3 to 5 cm wide, and has a capacity of about 30 to 60 ml. The inner surface of the gallbladder is covered with mucous membrane and has well-developed folds. When the gallbladder contracts and empties, the folds are tall and branched; when the gallbladder is full, the folds become shorter. The mucosal epithelium is a single-layer columnar structure. There are many microvilli on the free surface of the cells, the mitochondria and rough endoplasmic reticulum in the cytoplasm are relatively developed, and a small amount of mucus granules can be seen in the top cytoplasm. The lamina propria is a thin layer of connective tissue with abundant blood vessels, lymphatic vessels and elastic fibers. The epithelium between the wrinkles often extends into the lamina propria to form deep mucosal sinuses. Similar to mucous glands, they secrete mucus. The muscular layer is relatively thin and the muscle fibers are arranged irregularly, in circular, oblique, and longitudinal patterns. The outer membrane is thicker and is a loose connective tissue containing blood vessels, lymphatic vessels, and nerves. Most of the outer membrane surface is covered with serous membrane. The cystic duct connects the gallbladder, hepatic bile duct and common bile duct. The gallbladder is connected to the common bile duct through the bile duct. Its mucosa has many spiral folds, and a small number of goblet cells are scattered in the single-layer columnar epithelium of the mucosa. There are mucous glands in the lamina propria, and the muscular layer is thicker and mainly arranged in a circular pattern. The bile produced by the liver is discharged through the hepatic duct and is generally stored in the gallbladder first. The volume of the gallbladder cavity is about 40 to 70 ml. Epithelial cells absorb water and inorganic salts (mainly Na+) in bile and transport them to the intercellular spaces between epithelial cells through the plasma membrane on the side of the cells. The width of the gaps may vary depending on the amount of absorbed fluid. The absorbed water and inorganic salts enter the blood vessels and lymphatic vessels of the lamina propria through the basement membrane. The contraction and emptying of the gallbladder are regulated by hormones. After eating, especially high-fat foods, the endocrine cells in the small intestine secrete cholecystokinin, which flows to the gallbladder through the blood, stimulating the contraction of the gallbladder muscle layer and excreting bile. This article gives a detailed introduction to the relationship between the normal size of the gallbladder and health. I believe that many people have understood the relationship between the normal size of the gallbladder and health through the above understanding. Therefore, after understanding it, in order to make your gallbladder healthier, you should ensure the health of your gallbladder in your daily diet and the regularity of your life. |
