Human Digestion Summary
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.
Amount of Time it Takes
It does not really take long for the food we eat to go through the digestive system considering

Digestion first begins with the mouth. When you put food into your mouth your teeth and saliva helps to break down food into small molecules that absorbs into your bloodstream, your tongue finishes this process off by pushing the food into your throat in order for you to swallow. Food then goes through the esophagus and the esophagus muscles pushes the food into the stomach. While in the stomach digestive juices such as enzymes and acids assists in breaking down the food into paste. The food and digestive juices mixes and remains in the stomach for at least two hours. After departing the stomach food then goes through the small intestine. This is the most important part of digestion. The food paste travels through the small intestine and nutrients such as carbohydrates, minerals, proteins, fats, and vitamins are absorbed by villi and then goes through the bloodstream. The food which is undigested then goes through the large intestine as paste. Water is taken from the paste and it then becomes solid waste. The solid waste gathers inside the rectum which is at the end of the large intestine. Lastly, the waste goes through the anus (Hillendale Health, 2013).
Other Components of the Digestive System While going through the stages, what is failed to be mentioned in the travel of the food is the gall bladder, liver, and pancreas. The gall bladder basically acts a storage facility for bile, which is produced by the liver (Inner body, 2013). The role that the pancreas plays in this is storing the bile after it goes through the gall bladder. It is stored in an area called the duodenum (Johns Hopkins, 2012).

    The beginning of the digestive process starts with the smell and sight of food which activate the salivary glands. The mouth is the point at which food enters the digestive tract and continues the digestive process by chewing food. The food is then broken down into pieces and moistened by salivary glands which turn food into a bolus. The bolus goes down the pharynx into the esophagus which connects the pharynx to the stomach. The stomach is an organ that mixes food and secretes gastric juice. The bolus, once in the stomach, is mixed into a semiliquid mass called chime. The stomach is close together with the liver and pancreas but does not get assistance from these organs. The chime then enters…

    When we vomit, the acidic nature of our stomach contents becomes immediately apparent both from the taste and from the burning sensation in our throats. The purpose of this acidity is to kill any bacteria we swallow with our food. In the stomach, digestive enzymes and a muscular churning action combine to reduce our food to a thick liquid called chyme. Chyme exits the stomach through a second sphincter and enters the small intestine. Typically, it takes the stomach about 4 hours to process a meal. The small intestine is about 20 feet long. In the duodenum, the first foot of the small intestine, digestion continues with the breakdown of proteins, fats, carbohydrates, and nucleic acids. Some of the digestive enzymes at work in the duodenum are made by the small intestine itself. Others are made by the pancreas. Pancreatic enzymes play an important role in neutralizing food, which arrives from the stomach in a highly acidic condition. In addition, the small intestine receives bile, a substance that is produced in the liver and stored in the gall bladder. Bile is an emulsifier?it breaks fats into tiny droplets that are more easily attacked by enzymes. Beyond the duodenum, the rest of the small intestine functions primarily in absorbing nutrients into the body. In order to be able to do this efficiently?that is, rapidly?the small intestine has a huge surface area. It is covered with numerous fingerlike projections called villi, each of which is in turn covered with tiny little projections called microvilli. Flattened, the small intestine would fill the area of a tennis court! Digested nutrients are absorbed across the surface of the small intestine into capillaries found inside each villus.…

    The gastrointestinal tract starts with the mouth, which leads to the gullet via the stomach, small intestine, large intestine, and ends at the anus. In due course of the journey, the ingested food is broken down by both physical and chemical means to release nutrients which are absorbed into the blood stream. The ingested food is physically broken down in the mouth by chewing so as to reduce its size for increased surface area over which enzymatic reaction will take place. Enzymatic reaction is known as digestion and this is defined as the chemical breakdown of the ingested complex food molecules by the action of biological enzymes, into simplest form that can be absorbed into the blood stream and assimilated into living cells. In human beings, various components of the ingested food are digested and absorbed at various sections of the alimentary canal .…

    Digestion begins in the mouth. A brain reflex triggers the flow of saliva when we see or even think of food. Saliva moistens the food while the teeth chew it up and make it easier to swallow. Amylase, which is the digestive enzyme, found in saliva, starts to break down starch into simpler sugars before the food even leave the mouth. The nervous pathway involved in salivary excretion requires stimulation of receptors in the mouth, sensory impulses to the brain stem and parasympathetic impulses to salivary glands. Swallowing his food happens when the muscles in his tongue and mouth move the food into his pharynx. The pharynx, which is the passage way for food and air, a small flap of skin called the epiglottis closes over the pharynx to prevent food from entering the trachea and causing choking. For swallowing to happen correctly a combination of 25 muscles must all work together at the same time. After being chewed and swallowed the food enters the esophagus or gullet is the muscular tube in vertebrates through which ingested food passes from the throat to the stomach. It connects the pharynx, which is the body cavity that is common to both the digestive and respiratory systems behind the mouth, with the stomach, where the second stage of digestion is initiated. The esophagus is a long tube that runs from the mouth to the stomach. It uses rhythmic wave like muscle movements called peristalsis to force food from the throat into the…

    The human digestion system consists of a series of organs and glads that process the food that we eat. The digestion process starts when food enters the mouth, then with the chewing of food. The salivary glads help break down the food with enzymes so that it is easier to swallow. While the food is being chewed it is turned into bolos, which then travels down the pharynx and through the esophagus. The esophagus is the long tube that runs from the mouth to the stomach. After the food reaches the stomach it is partially digested and mixed with the stomach acids called chyme.…

    The process of digestion has many stages with the first starting in the oral cavity. Within the system, food passes through a tube called the alimentary canal, more commonly known as the gastrointestinal tract. The tract is made up of the oral cavity, pharynx, oesophagus, stomach, small intestines, and large intestines. To provide energy and nutrients to the body, major functions take place in the digestive system which include; ingestion, secretion, mixing and movement, digestion, absorption and excretion.…

    every part of the gastrointestinal tract is designed to help in the digestive process in a specific way. The mouth is involved in chewing also know as masticating. The purpose is to break down food into small enough pieces to pass through the esophagus and enter the stomach. The food is moistened with saliva helping turning it into bolus in order to turn initiate the digestion of food. The esophagus is a tube like muscle which use contractions to pass food from the mouth into the stomach it does not help with the digestive or absorptive function. The stomach acts like a sort of storage depot for food, but also acts as a place in which mechanical and chemical breakdown of food happens. The small intestine absorbs water, electrolytes, proteins, fats and carbohydrates. Whereas the large intestine is where the food matter and water that can’t be absorbed is the formed into stools. The rectum is a temporary storage area for feces before passed.…

    Once I have taken a bite out of my delicious favorite meal, the digestive system gets to work. It all begins in the mouth, chewing the food small enough to swallow. Salvia is squirted into the food to moisten and soften the food. Salvia contains enzymes, which break down the starches in food. Once the tongue forms the food into a ball to be swallowed, it is sent down the pharynx. The pharynx contains sphincters that help keep your food down once you swallow. Next, it makes its way to the esophagus, which is simply a transportation tube from the mouth to the stomach. It then reaches the stomach, which uses chemicals to make the food particles tinier. These chemicals are called gastric juices and include hydrochloric acid and enzymes. Once the stomach mixes with the chemicals, it is formed into a cream-like liquid called chyme. The gallbladder takes over from here hitting the food with more chemicals, one of them called bile. Bile is mixed with our food breaking down the fat into droplets, which will supply us with energy later on. From there, the pancreas uses digestive juice to break down…

    Digestion begins in the mouth when one eats food. It begins the moment one takes a sandwich bite. The teeth are used to break the sandwich that contains lettuce and pickles into smaller particles or boluses so that the enzymes can digest the food much easier. Lettuce contains carbohydrates, proteins and fat. The tongue helps turn food in the mouth and mix with the saliva in the mouth which contains salivary amylase enzyme. It then passes through the esophagus to the stomach which is a mixer and grinder of food. The stomach secrets Hydrochloric acid and enzymes that are used in the breaking down of the food. The food then leaves the stomach in form of a liquid or fluid into the small intestines where it is now absorbed into the system. The absorption…

    The digestive system starts with the saliva in your mouth. The salivary glands recognize the sight and smell of food. The saliva contains the enzyme salivary amylase which begins the chemical digestion of food. The food you eat is moistened, chewed up by your teeth and then is transferred into a bolus. Once the bolus leaves the mouth, it moves into your pharynx, where it is then swallowed. Once the bolus reaches the stomach, it is mixed with different acids and from there it is transformed into a chyme. Most people think that the food is digested in the stomach, but the food that we eat is only partially digested in our stomachs. Chemical digestion in the stomach is caused by gastric juice which is a mixture of water, mucus, hydrochloric acid and pepsin (Grosvenor & Smolin, 2006, pg. 73). Our liver, gallbladder and pancreas are located near our stomach and they aid in the digestive process once the chyme has reached the small intestine. The liver and gallbladder help with the digestion of fat. When the chyme is in the process of leaving the stomach, there are signals by the small intestine. The signals are sent from the brain, small intestine or the stomach. The small intestine is about 20 feet long. The small intestine is also the primary site for absorption or water, vitamins and minerals (Grosvenor & Smolin, 2006, pg. 75). A large amount of the digestion process takes place in the…
