THE STOMACH
Posted by adminAs is true of any other organ in our body, the stomach is a miracle of divine Creation. The mucous lining of the stomach, like all other mucous membranes, consists of elastic rubber-like connective tissues permeated by a network of arteries, veins, lymphatic vessels and nerves. All of these minute vessels and nerve bundles taper off towards the inside into extremely fine, microscopic end loops surrounding the stomach glands. The inner lining of the stomach is not smooth, but drawn up into folds, the larger rugae, or folds, being subdivided into many smaller ones. When magnified under a microscope they look like the fins of an old-fashioned central-heating radiator. The rugate inner wall of the stomach is covered with about five million tiny secretory cells. The microscopic nozzles secrete in precise amounts the enzymes pepsin and rennin making up the gastric juice, according to the particular requirements of the kind and quantity of the food that has been eaten. A sufficient amount of hydrochloric acid has also to be secreted because pepsin is activated only when there is acid present.
