Hunger is just a sensation. We feel hungry after several hours of empty stomach. We feel hungry when we feel emotional rush. We also feel hungry after 12 hours or 24 hours of empty stomach. This is to keep our body functioning properly. The body needs to maintain blood sugars at a balanced level, and the digestive system must stay in liquid form (not hardened).
Feeling hungry lasts for about 30 seconds, and the rest of it was a mere echo which lasts for about 30 minutes. Once we get food in our mouth, and starts eating, the sensation will change into feeling full in about 5 minutes later. This is like computer program which relates to time (biological clock).
Digestion in Mouth
Digestion mainly focuses on breaking food into smaller pieces so it's easier for the body to absorb nutrients. It begins when food enters the mouth. Saliva and teeth helps to break food into small chunks (like a ball), before it slowly passes through the throat and into the stomach.
Special treatment was given to Vitamin B12, which was detected early by the saliva, because Vitamin B12 cannot stand acidic environment. Therefore, the saliva wraps Vitamin B12, so it can travel through our acidic stomach.
Digestion in Stomach
Stomach puts in some more enzymes which further break food into vomit-like. After an hour or two, when food has become thick semi-liquid (similar to pure tomato juice), it enters the spleen.
Digestion of Blood Cells
Spleen will then recycle all red blood cells and white blood cells that are used for digestion so far (the blood cells have gotten old). After breaking down the red blood cells and white blood cells, it will send iron and the recycled blood cells to liver.
Digestion of Carbohydrates and Proteins
Inside the liver, all toxins and dirt will be filtered and removed. It also breaks down carbohydrates and proteins. Excess sugars from carbohydrates digestion will be stored, and excess proteins will be stored in two types; body fat and cholesterol.
Fat is then further broken down in the gallbladder, and then salt was attached to the fat so the fat won't crystallise. When there are too much fat in the gallbladder, the digestion won't finish properly, and when calcium binds to the fat, gallstones will form. The enzymes used to process fat in the gallbladder is then recycled for further reuse.
Sugar is then further processed in the pancreas. When it detects that there are too many sugars in the blood, it will move sugars into muscles for energy storage. On the other hand, when it detects that there aren't enough sugars in the blood, it will take sugars stock from the liver, and release it for circulation through blood.
Absorption
The pancreas will also release more enzymes to the small intestines to help digestion process. The small intestines absorb 95% of the food. There are other mixtures added to the digested food, and when the composition is right, the blood can start absorbing nutrients from the small intestines. When food doesn't reach small intestines in time, the released gastric acid would damage the walls of the intestines.
In the case of Vitamin B12, there will be another enzyme (from pancreas) that opens the saliva wrapper, so the transporter enzyme can stick to Vitamin B12, and circulate it through the blood. When small intestines have finished absorbing nutrients, the remaining food (semi-solids, or feces) will go to the large intestines (colon).
Inside the colon (large intestines) where the environment is more acidic, blood absorbs water, minerals, Vitamin K, and other vitamins. The digestion process slows down because food undergoes fermentation process. There are good bacteria to help with the fermentation process too. It takes about 12 to 50 hours before food is removed from the body by defecation.
Digestion Final Step
When everything is done, the blood will then travel to the liver, to remove any toxic components first, before circulating the nutrients throughout the body.
