Stomach or compound racemose resembling the duodenal Brunner's glands The "fundic glands", are found in the fundus and body of the stomach. They are simple almost straight tubes, two or more of which open into a single duct. They secrete hydrochloric acid (HCl) and intrinsic factor. The "pyloric glands" are located in the antrum of the pylorus. They secrete gastrin produced by their G cells. About 20,000 protein coding genes are expressed in human cells and nearly 70% of these genes are expressed in the normal stomach. Just over 150 of these genes are more specifically expressed in the stomach compared
Food spoilage bacteria grow most rapidly, for over 24 hours. Canning of food can preserve food for a particularly long period of time, whether canned at home or commercially. Canned food is vacuum packed in order to keep oxygen out of the can that is needed to allow bacteria to break it down. Canning does have limitations, and does not preserve the food indefinitely. Lactic acid fermentation also preserves food and prevents spoilage. Food spoilage Spoilage is the process in which food deteriorates to the point in which it is not edible to humans or its quality of edibility becomes reduced. Various
