The BIG MAC is placed in the mouth. The bread is mainly starch, the special sauce is mainly fat, lettuce, pickles, and onions are niacin. The beef patties are protein,and cheeseis a form of calcium, fat, and protein. The piece of the BIG MAC is placed in the mouth and chewed, the starch is being digested by saliva. The starch becomes a kind of sugar which is used as a nourishment for the cells. Saliva changes food to a form that can be used by the body called enzymes. The burger is swallowed and passes into the esophagus.
This is the muscular tube that contracts along its length to push the food down into the stomach. In the alimentary canal the meat and special sauce is being absorbed. The fat in the sauce is used for energy and the protein in the meat is used to build muscles, the lettuce, pickles, onions are also absorbed. In the stomach, which is a muscle, the food is churned about while digestive juices pour int from glands in the stomach wall. Eventually, the the churning action moves food out of the stomach and into the small intestine. The lever contributes to this digestive process by secreting into the small intestine, a liquid called bile. The pancreas secretes pancreatic juice which further aids in dissolving food. The small intestine undergoes continual muscular contractions called peristalses. This action pushes food into the large intestine. This surface of the small intestine has a large number of threadlike projections called villi.
The digested, liquified food is absorbed through the villi, and passes into capillaries that are inside the villi. Now the food is in the bloodstream. Not all parts of the BIG MAC can be digested.Those parts which are indigestible pass through the large intestine to its lower part, called the rectum. Eventually, the indigestible food is eliminated from the rectum through the anus. This is the complete teck that the BIG MAC follows when it is eaten.

The first digestion process starts at the mouth in which cooked starch is reduced into simpler sugars by the action of ptyalin. Digestion of the remaining cooked starch is completed by amylase in the small intestine where duodenum and pancreas take part. Absorption of simpler sugars as the products of digested starch, take place in the small intestine as well. The digestion of proteins starts in the stomach in which protein molecules are reduced into amino acids by the action of hydrochloric acid and the protein digestive enzymes called proteases. Digestion of the remaining proteins is completed at the small intestines by the action of trypsin, and the amino acids are absorbed into the blood stream. Digestion of lipids starts at the small intestines in which fats and oils are emulsified and digested by the enzyme called lipase into fatty acids. Vitamins and minerals are generated and absorbed in the large intestines. The discussion will focus on the digestion of ingested…

When carbohydrates are consumed during a meal, catabolism originates in the mouth. The salivary enzyme α-amylase breaks down the carbohydrates through the hydrolysis of the α1->4 glycosidic bonds. This is followed by the further breakdown of the complex polysaccharides in the small intestine down to monosaccharides units in order for the glucose to be absorbed directly into the bloodstream.…

We all love to eat. I remember my parents used to tell me that in order for my food to digest properly, I would have to chew it one hundred times on both side to make it small as possible. They said that if the food was smaller it could digest quicker and easier. But most people do not know what happens to their food after they have chewed it up and swallowed it. Some may think that right after the food is swallowed, it goes straight to the stomach. The purpose of this essay is to discuss the path food follows as it goes through the digestive system.…

3. The whole thing begins with our Pavlovian response. Some of you might be familiar with this through having taken Psychology. This was a Russian scientist who used dogs to measure the amount of saliva they had. There was a bell that he would ring, but basically he conditioned them so that when he rang the bell they would start to salivate, and the same thing works with us (Video). So basically when we see it we begin to salivate, we have glands, three big glands that are going to produce saliva that is going to empty into our mouth. Now the saliva has water in it but it mostly has mucus and also an enzyme called amylase. And amylase breaks down starch (amylose starch) and so it’s going to break down, or start to break down the carbohydrate. So basically are teeth…

From the stomach, the burger goes through the pyloric sphincter and into the small intestine. In the first 25 cm of the small intestine, the food goes through the duodenum, a place where pancreatic enzymes and bile from the live are stored. Bile, along with the enzyme lipase, breaks down fat while the enzyme nuclease breaks down nucleic acids and various enzymes, such as trypsins and peptidases, break down the proteins. These substances are called by hormones which act based on stimuli received, such as the food in the duodenum. Absorption also occurs in the small intestine because of its large surface area. It has a very large surface area because villi, or finger like projections on the surface, contain microvilli, smaller projections on the surface of the villi. Because of this, the surface area of the small intestine is greatly increased.…

The absorbed substances are then moved through the blood vessels to different organs of the body where they are used to build complex substances, such as the proteins required by our body.
