怎么关闭器官

肢体的一段伤，手指头弄掉了一个是吧？甚至更大的地方还有别的地方断的，哈哈，你掉下来的器官怎么保存？这都是见过的标准，怎么保存哈，那边一个手指头打底断了。无菌纱布最好，当然没有无菌纱布怎么办？这干净的毛巾 用纸啊，你把它包起来，然后再放到一个干净的塑料袋里封口，再放到有冰水也好啊，有冰块也好啊，放到一个就小冷箱里边，带着他到医院去。为什么要裹一层干净的毛巾啊？ 你要不裹毛巾你别用冰块，不就直接把他就冻伤了吗？他是要低温的，但你冻伤了也不行啊，有时候人家不就不懂得这些人啊，原来什么都见过。拿酒精泡着拿来的， 你这不直接就泡了个标本来吗？直接做病理去好了，你完全不能用了。还有那盐水泡的，你本来能清疮的，这一泡就不合适了。因为这种当时一慌乱，有心眼还好先打幺二零，幺二零说怎么办怎么办？他有的人可能当时就 找找找找找，这怎么才这这拿点水冲冲就拿来了，拿个袋子冲点水拿来了，这种有时候就影响他在后续做手术就成功率了。

what exactly happens in our stomachs when we eat even before we have taken the first bite of a meal， the brain sends impulses to the stomach these impulses start the production of secretions in the stomach and the upper part of the stomach， which acts as a reservoir expands the food passes into the stomach through the cardia at the stomach entrance this is a muscle that acts like a valve closing the top of the stomach， the top part of the stomach， the fundus is where food and the air that we swallow with every bite is collected this is where the stomach volume starts to adapt the fundus is an extremely adaptable structure the more food goes into the stomach the more it actively expands in the middle part of the stomach called the body gastric juice is produced and mixed with a massive chewed food the main component of gastric juice is gastric acid this eliminates bacteria in the food and also helps to prepare the food for the following stages of digestion， the muscular contractions of the stomach wall turn the food mass and mix it with gastric juice three contractions per minute move the food mass back and forth after a certain time， the contents of the stomach are adequately broken down in mixed and are passed in small quantities into the intestine via the pylorus as the stomach empties it gradually returns to its previous size。
