4 Although stratified squamous epithelium is relatively impermeable to HCl, a number of factors can dramatically enhance the damaging effects of HCl in this epithelium. In particular, bile salts and short-chain fatty acids are capable of breaking down the squamous epithelial barrier at an acid pH,...
The stomach is a sac that contains different gastric juices, acids, and enzymes that help break down food and digest it. Learn about the physiology of the stomach, the different gastric juices, and the process of digestion inside the stomach. ...
Lingual lipase then begins breaking down triglycerides into free fatty acids, and mono- and diglycerides. The breakdown of protein begins in the stomach through the actions of HCl and the enzyme pepsin. During infancy, gastric glands also produce rennin, an enzyme that helps digest milk protein....
3.They start breaking down food during the first hour or so after eating, when it's still in the upper stomach, waiting for stomach acid to collect in the lower stomach to break it down further. 在进食后的大约第一个小时内开始消化食物,这时食物仍在胃的上部,等待胃酸在胃下部聚集从而进一步消...
During digestion, the stomach is capable of dramatically lowering the pH of its contents, and of secreting pepsinogen to begin breaking down protein. However, both HCl and pepsinogen (which is converted to pepsin) are inherently damaging to mucosa, which possesses a number of mechanisms to ...
