The digestive system is a series of hollow organs joined in a long, twisting tube from the mouth to the anus (see figure). Inside this tube is a lining called the mucosa. In the mouth, stomach, and small intestine, the mucosa contains tiny glands that produce juices to help digest food. Two solid organs, the liver and the pancreas, produce digestive juices that reach the intestine through small tubes. In addition, parts of other organ systems (for instance, nerves and blood) play a major role in the digestive system. [Top] Why is digestion important? When we eat such things as bread, meat, and vegetables, they are not in a form that the body can use as nourishment. Our food and drink must be changed into smaller molecules of nutrients before they can be absorbed into the blood and carried to cells throughout the body. Digestion is the process by which food and drink are broken down into their smallest parts so that the body can use them to build and nourish cells and to provide energy. [Top] How is food digested? Digestion involves the mixing of food, its movement through the digestive tract, and the chemical breakdown of the large molecules of food into smaller molecules. Digestion begins in the mouth, when we chew and swallow, and is completed in the small intestine. The chemical process varies somewhat for different kinds of food. Movement of Food Through the System The large, hollow organs of the digestive system contain muscle that enables their walls to move. The movement of organ walls can propel food and liquid and also can mix the contents within each organ. Typical movement of the esophagus, stomach, and intestine is called peristalsis. The action of peristalsis looks like an ocean wave moving through the muscle. The muscle of the organ produces a narrowing and then propels the narrowed portion slowly down the length of the organ. These waves of narrowing push the food and fluid in front of them through each hollow organ. The first major muscle movement occurs when food or liquid is swallowed. Although we are able to start swallowing by choice, once the swallow begins, it becomes involuntary and proceeds under the control of the nerves. The esophagus is the organ into which the swallowed food is pushed. It connects the throat above with the stomach below. At the junction of the esophagus and stomach, there is a ringlike valve closing the passage between the two organs. However, as the food approaches the closed ring, the surrounding muscles relax and allow the food to pass. The food then enters the stomach, which has three mechanical tasks to do. First, the stomach must store the swallowed food and liquid. This requires the muscle of the upper part of the stomach to relax and accept large volumes of swallowed material. The second job is to mix up the food, liquid, and digestive juice produced by the stomach. The lower part of the stomach mixes these materials by its muscle action. The third task of the stomach is to empty its contents slowly into the small intestine. Several factors affect emptying of the stomach, including the nature of the food (mainly its fat and protein content) and the degree of muscle action of the emptying stomach and the next organ to receive the contents (the small intestine). As the food is digested in the small intestine and dissolved into the juices from the pancreas, liver, and intestine, the contents of the intestine are mixed and pushed forward to allow further digestion. Finally, all of the digested nutrients are absorbed through the intestinal walls. The waste products of this process include undigested parts of the food, known as fiber, and older cells that have been shed from the mucosa. These materials are propelled into the colon, where they remain, usually for a day or two, until the feces are expelled by a bowel movement. Production of Digestive Juices The glands that act first are in the mouth—the salivary glands. Saliva produced by these glands contains an enzyme that begins to digest the starch from food into smaller molecules. The next set of digestive glands is in the stomach lining. They produce stomach acid and an enzyme that digests protein. One of the unsolved puzzles of the digestive system is why the acid juice of the stomach does not dissolve the tissue of the stomach itself. In most people, the stomach mucosa is able to resist the juice, although food and other tissues of the body cannot. After the stomach empties the food and juice mixture into the small intestine, the juices of two other digestive organs mix with the food to continue the process of digestion. One of these organs is the pancreas. It produces a juice that contains a wide array of enzymes to break down the carbohydrate, fat, and protein in food. Other enzymes that are active in the process come from glands in the wall of the intestine or even a part of that wall. The liver produces yet another digestive juice—bile. The bile is stored between meals in the gallbladder. At mealtime, it is squeezed out of the gallbladder into the bile ducts to reach the intestine and mix with the fat in our food. The bile acids dissolve the fat into the watery contents of the intestine, much like detergents that dissolve grease from a frying pan. After the fat is dissolved, it is digested by enzymes from the pancreas and the lining of the intestine. Absorption and Transport of Nutrients Digested molecules of food, as well as water and minerals from the diet, are absorbed from the cavity of the upper small intestine. Most absorbed materials cross the mucosa into the blood and are carried off in the bloodstream to other parts of the body for storage or further chemical change. As already noted, this part of the process varies with different types of nutrients. Carbohydrates. It is recommended that about 55 to 60 percent of total daily calories be from carbohydrates. Some of our most common foods contain mostly carbohydrates. Examples are bread, potatoes, legumes, rice, spaghetti, fruits, and vegetables. Many of these foods contain both starch and fiber. The digestible carbohydrates are broken into simpler molecules by enzymes in the saliva, in juice produced by the pancreas, and in the lining of the small intestine. Starch is digested in two steps: First, an enzyme in the saliva and pancreatic juice breaks the starch into molecules called maltose; then an enzyme in the lining of the small intestine (maltase) splits the maltose into glucose molecules that can be absorbed into the blood. Glucose is carried through the bloodstream to the liver, where it is stored or used to provide energy for the work of the body. Table sugar is another carbohydrate that must be digested to be useful. An enzyme in the lining of the small intestine digests table sugar into glucose and fructose, each of which can be absorbed from the intestinal cavity into the blood. Milk contains yet another type of sugar, lactose, which is changed into absorbable molecules by an enzyme called lactase, also found in the intestinal lining. Protein. Foods such as meat, eggs, and beans consist of giant molecules of protein that must be digested by enzymes before they can be used to build and repair body tissues. An enzyme in the juice of the stomach starts the digestion of swallowed protein. Further digestion of the protein is completed in the small intestine. Here, several enzymes from the pancreatic juice and the lining of the intestine carry out the breakdown of huge protein molecules into small molecules called amino acids. These small molecules can be absorbed from the hollow of the small intestine into the blood and then be carried to all parts of the body to build the walls and other parts of cells. Fats. Fat molecules are a rich source of energy for the body. The first step in digestion of a fat such as butter is to dissolve it into the watery content of the intestinal cavity. The bile acids produced by the liver act as natural detergents to dissolve fat in water and allow the enzymes to break the large fat molecules into smaller molecules, some of which are fatty acids and cholesterol. The bile acids combine with the fatty acids and cholesterol and help these molecules to move into the cells of the mucosa. In these cells the small molecules are formed back into large molecules, most of which pass into vessels (called lymphatics) near the intestine. These small vessels carry the reformed fat to the veins of the chest, and the blood carries the fat to storage depots in different parts of the body. Vitamins. Another vital part of our food that is absorbed from the small intestine is the class of chemicals we call vitamins. The two different types of vitamins are classified by the fluid in which they can be dissolved: water-soluble vitamins (all the B vitamins and vitamin C) and fat-soluble vitamins (vitamins A, D, and K). Water and salt. Most of the material absorbed from the cavity of the small intestine is water in which salt is dissolved. The salt and water come from the food and liquid we swallow and the juices secreted by the many digestive glands. [Top] How is the digestive process controlled? Hormone Regulators A fascinating feature of the digestive system is that it contains its own regulators. The major hormones that control the functions of the digestive system are produced and released by cells in the mucosa of the stomach and small intestine. These hormones are released into the blood of the digestive tract, travel back to the heart and through the arteries, and return to the digestive system, where they stimulate digestive juices and cause organ movement. The hormones that control digestion are gastrin, secretin, and cholecystokinin (CCK): Gastrin causes the stomach to produce an acid for dissolving and digesting some foods. It is also necessary for the normal growth of the lining of the stomach, small intestine, and colon. Secretin causes the pancreas to send out a digestive juice that is rich in bicarbonate. It stimulates the stomach to produce pepsin, an enzyme that digests protein, and it also stimulates the liver to produce bile. CCK causes the pancreas to grow and to produce the enzymes of pancreatic juice, and it causes the gallbladder to empty. Additional hormones in the digestive system regulate appetite: Ghrelin is produced in the stomach and upper intestine in the absence of food in the digestive system and stimulates appetite. Peptide YY is produced in the GI tract in response to a meal in the system and inhibits appetite. Both of these hormones work on the brain to help regulate the intake of food for energy. Nerve Regulators Two types of nerves help to control the action of the digestive system. Extrinsic (outside) nerves come to the digestive organs from the unconscious part of the brain or from the spinal cord. They release a chemical called acetylcholine and another called adrenaline. Acetylcholine causes the muscle of the digestive organs to squeeze with more force and increase the "push" of food and juice through the digestive tract. Acetylcholine also causes the stomach and pancreas to produce more digestive juice. Adrenaline relaxes the muscle of the stomach and intestine and decreases the flow of blood to these organs. Even more important, though, are the intrinsic (inside) nerves, which make up a very dense network embedded in the walls of the esophagus, stomach, small intestine, and colon. The intrinsic nerves are triggered to act when the walls of the hollow organs are stretched by food. They release many different substances that speed up or delay the movement of food and the production of juices by the digestive organs.

手势侧滑导航在 iOS 中尤其常见，在项目中，经常和其打交道，但是经常发现，当侧滑到根控制器（第一级界面）时，继续快速使用侧滑手势 popGesture 会导致卡住。有时候，想要监听某个界面的侧滑手势是否结束来做一些其他操作，比如，在一个有 定时器（NSTimer） 的界面，使用侧滑到上一级页面，会导致该界面无法释放，这就需要知道当前侧滑手势是否已经结束，在结束时 移除（NSTimer） 等等。 滑动到首页（一般就是根控制器所属的第一级界面）会卡死， 这是iOS系统本身存在的一个BUG ，解决方案就是创建一个 BaseNavigationController （继承 UINavigationController ），在 BaseNavigationController 中监听 代理方法 ，判断当子视图控制器数 viewControllers 大于 1 时，允许 pop 手势可以滑动。在 BaseNavigationController.m 中，如下： 一般我们很少会需要监听侧滑到上一级的手势的情况，这种场景可能会出现在一些特殊处理中，比如当使用侧滑手势 pop 到上一级时，由于一些操作未完成，当前 self 被持有，而导致 dealloc 方法没有被执行，换句话说，当前 view controller 没有释放造成内存泄漏，这种情况下，监听侧滑手势是否执行就有必要了。在 BaseNavigationController.m 中，如下： 在 - (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated 中，可以使用 - (void)notifyWhenInteractionChangesUsingBlock: (void (^)(id <UIViewControllerTransitionCoordinatorContext>context))handler 监听到侧滑手势的情况，如果 context.isCancelled 为 YES ，说明用户侧滑的时候取消了滑动，即没有返回到上一级页面，反之，如果为 NO ，说明将 pop 到上一级页面，当前页面即将被释放。 因此，当 context.isCancelled 为 NO 时，我们可以发送一个通知（ notification ）到当前正在操作侧滑手势 pop 的这个页面，在这个页面做监听，就可以在收到通知时，执行你想要的操作就可以了。 比如，在 demo （ 文末有提供 ）中，我们监听如下： 个人博客 Demo地址 2021-03-12

　　As a woman, one of the biggest mistakes I"ve made that mistake once the love of life as a whole. During that time, we can say only live for love, to love as all the hope and meaning of life. Of course, love and finally out of the question. Fortunately, later I realized that love is just a part of life, that part of it is not even a pillar of, but for the life of that part of the icing on the cake.　　At that time, I think it is a problem because of the love that he began to go wrong, life began to go wrong. In fact, when looking back found that, in fact, when I first went wrong, entangled in a variety of inexplicable fear among the hapless love will follow. When love is when something goes wrong, if two people love just want to fix, rather than objectively reflect and improve yourself, then once again a beautiful love, rescue is not coming back. A person like anger Wang, from chicken pox, you do not try to send a fire, just touch some acne plaster, will not have much use.　　Later, I will no longer worry about. Fear will only make a good thing bad, bad thing worse. Many girls said to me: "I just did not feel safe." But the "security" is what? What men really give you a sense of security? Maybe you"re worried now, why they have not found a boyfriend; when you find a boyfriend, you began to worry, he does not marry me how to do; when he married you, you have to worry about his derailed how many people do ...... so again and again worried endlessly, where there is time to enjoy the love? To feel the love the most sincere, most beautiful part?　　There is no sense of security, either from their own distrust; either due to distrust each other. If you really love a man, and make sure he worthy of your love, then choose to trust him. As for their lack of trust, which requires long-term self-regulation and encouragement. The most important is a woman, no matter how crazy it was love, it must have some of their hobbies, their friends, their own ideas, and more importantly - there must be an independent personality. Only in this way will you trust yourself.　　Do not put the blame on his own misfortune late love, or love ring true, in fact, when you take care of all parts of life in addition to love outside the harvest you will naturally want to love.

EYETOY的原理其实并不复杂，摄像头以固定的速率采集图像，当场景内无变化时，前后两幅图像内容一致，当有物体运动时则产生差异，因此通过简单的对相邻两帧图像相减，得到画面中不同的部分，即可以感知是否有运动物体及运动物体的一些属性，比如大小，位置和颜色等。在这其中当然还有一些细节需要处理，流程虽简单，但是做好却不易。这一简单原理使得EYETOY仍存在一些瑕疵，例如当玩家动作过小，或是玩家所处的环境、服装色彩与身体过于接近时，EYETOY都可能出现短暂的无法识别问题。 EYETOY是第一个真正意义上实现大规模商用化的体感技术。但它最终却并未流行起来并得以普及，至少在其问世两年后，几乎再也听不到任何游戏厂商希望针对它来开发新游戏的声音。这是因为EYETOY有一个致命的软肋—它的原理注定了它只能摄取二维图像并加以解析，而在三维游戏世界中，多数游戏动作更偏向于三维.Wii之所以会比EYETOY成功，就是因为它解决了这个最令游戏厂商头痛的问题。
