The base of the duodenum, jejunum, and ileum contains the paneth cells, that secrete antibacterial to protect the intestine from microbes. These cells help prevent the excessive growth of intestinal flora. To sum up, the duodenum is concerned and the digestion of food, absorption of nutrients, regulation of the rate of gastric emptying and hunger, and the movement of food through the intestinal tract. It has been observed that more food and nutrients are absorbed in the duodenum than the stomach. The gastric bypass surgery (used for treating morbid obesity) often involves the duodenum, due to its immense importance in the absorption of nutrients, and regulation of hunger and movement Exo Slim of food. The gallbladder is a small, green, pear-shaped organ located in the abdominal cavity of vertebrates. It grows to a length of 8 centimeters, and has a diameter of 4 centimeters. The function of the gallbladder is to store the bile secreted by the liver. The gallbladder is located beneath the liver. Its location corresponds to the lowest ribs, on the right side of the rib cage. The abdominal cavity in which the gallbladder is located, is termed as the gallbladder fossa, which is nothing but a depression on the undersurface of the liver, between the quadrate and the right lobes. The organs that come in contact and the gallbladder, are the liver, the abdominal wall, the transverse colon, and the duodenum or small intestines. The cystic artery, a branch of the right hepatic artery, supplies oxygenated blood to the gallbladder, while the deoxygenated blood is carried out by the cystic vein.
