Some of these reactions suggest an allergic cause, while many others do not appear to be allergic, but rather an intolerance. Reports of reactions to food additives have included the following: Skin urticaria/angioedema. atopic dermatitis.
The gastric glands are located in different regions of the stomach. These are the fundic glands, the cardiac glands, and the pyloric glands. The glands are found in the gastric pits of the stomach lining.The various cells of the glands secrete mucus, pepsinogen, hydrochloric acid, intrinsic factor, gastrin, histamine and bicarbonate.he cardiac glands are found in the cardia of the stomach which is the part nearest to the heart, enclosing the opening where the oesophagus joins to the stomach. Only cardiac glands are found here and they primarily secrete mucus.
The main constituent of gastric acid is hydrochloric acid which is produced by parietal cells (also called oxyntic cells) in the gastric glands in the stomach. Its secretion is a complex and relatively energetically expensive process.he pH of gastric acid is 1.5 to 3.5 in the human stomach lumen, the acidity being maintained by the proton pump H+/K+ ATPase. The parietal cell releases bicarbonate into the bloodstream in the process, which causes a temporary rise of pH in the blood, known as an alkaline tide.
