Analysis Of The Digestive Tract

The alimentary canal is where the digestive system takes place; it has different components in order for food to be thoroughly processed. The digestive system is composed of an enteric nervous system and has four layers of tissues; the mucosa, submucosa, muscularis externa, and serosa. Food enters through the mouth and passes through the esophagus, stomach, small intestine, and the large intestine before exiting the body through the anal canal. This occurs within the digestive system in four main steps; ingestion, where food enters through the mouth, digestion where food is broken down physically and chemically, absorption where nutrients are taken to their desired organ for use in the body, and elimination where waste is removed from the body due to being useless or toxic.When it comes to the human body there are plenty of components that we take for granted. Think about it, when was the last time you dwelled upon the function of your saliva or pondered on the responsibility of the esophagus? If you are like me, the answer to the question is simple, never. It is because our body is one of the greatest and yet most underappreciated machinery known to man. Within that system, which tends to get a lack of appreciation, stands alone one main process that we utilize on a daily basis and rarely give credence to its importance. This process is known as digestion, which occurs in the alimentary canal also known as the digestive system. The digestive system consists of the

A Muscular tube which connects the posterior end of the oral and nasal cavities to the oesophagus and larynx. It consist of three parts: nasopharynx, oropharynx and laryngopharynx. Because of its dual functions, pharynx consists of a flap of connective tissue called the epiglottis which acts as a switch allowing food passage into the oesophagus.

The digestive system absorbs the minerals and nutrients from the foods that have been eaten. The break down of food beings in the mouth, where the

One day me and my friends were going to science class, we were so excited to go because we were doing an experiment on the digestive system the whole class went except tommy, when told him to stay to keep the class safe. When we left he opened a bag of chips and we sat in his hand and he ate us. First we went inside the mouth were tommy cut and grinds and triggered his chemical in saliva glands to work with the mechanism of the tongue salivary glands in your mouth makes salivary amylase, which begins the digestive process by breaking down starch when you chew your food,that's how the food into was cut into smaller pieces, after that he swallowed the food and we went down the esophagus we saw epiglottis which is a flexible flap at the end of the larynx connecting it to the throat, it acts like a switch permitting air to pass through as you swallow the food, then we saw the peristalsis , a peristalsis is a muscle contracting in a wave like motion to move the food to the stomach after that we saw the lining of the esophagus, the lining of that esophagus is called a mucosa it runs down the windpipe and heart in front of the spinal cord to prevent food from just dropping into the windpipe, this is starting the digestion process, after that it takes us down the stomach, then

List the regions of the digestive tract and the accessory organs of the digestive system

The human digestive system, like those of other vertebrates, is built around an alimentary canal - a one way tube that passes through the body. The function of the digestive system is to convert foods into simple molecules that can be absorbed and used by the cells of the body.

Digestion starts in mouth and it is going through several steps. Teeth which are a Mechanical digestion start tearing and crushing the food down into small pieces so that the food will smoothly run down our throat. The salivary glands are located underneath the back of our tongues and that’s what is creating our saliva. The saliva is the Chemical Digestion is helping soften the food in the mouth so it is easy to swallow. Also saliva is the first out of several chemicals that is breaking the food into smaller bits. The tongue is the muscle that works with the food and saliva to form something similar to balls that can be swallowed. Also tongue contains taste buds so that we know if the food is salt, sweet, sour or bitter. Esophangus is a simple transportation tube that is joining the throat with stomach. When swallowing we are closing a trap door in our throats called the epiglottis. By closing this trap we are preventing the food prom going to trachea and into our lungs. Also Food moves down the esophangus using muscles not gravity. Stomach is the first stop after the Esophangus. When the food gets into stomach the stomach uses chemicals to try to make the food smaller. These chemicals are called gastric juices and they include hydrochloric acid and enzymes. (Enzymes are

All cells need nutrient and energy to live and this energy provided by processes that called digestion. For example, when we eat some things like bread, meat, and vegetable, although they are delicious, but they are not forms of nourishment for the cells, therefore they need to change into an acceptable form such as smaller molecules to absorb by blood and carry to body cells. Digestion is break downing of food into appropriate form to absorb into the bloodstream. Digestion system contains the digestive tract called alimentary canal and associated glands that secrete digestive juices for digestion of food. The digestion or breakdown is started when food is taken in the mouth and mastication performed by the teeth and exposed to certain enzymes. The primary function of teeth is grasped and holds the food in the mouth cavity, they also modified to serve as a grinding mill for chewing food that mentions to mechanical digestion. With the help of the teeth, tongue, and jaw movement, food are chewed and mixed with saliva that secreted in the mouth and allowing chemical digestion to happen. The digestion of a ham, cheese, and lettuce sandwich begins in the mouth. The food in the mouth active the endocrine glands to secretion digestive enzyme that called salivary amylase. It helps to break down carbohydrates and starch. Thus, at this stage, the bread of ham and cheese sandwich chemically digested. Amylase is a starch digesting enzyme which breakdowns bread (starch) into maltose that

Digestion is the process of breaking larger food particles into smaller particles that can pass through the plasma membrane. The digestive system is in charge of this process. To begin, the mouth receives food, breaking it into smaller particles by chewing, a form of mechanical digestion with the teeth, for absorption. The tongue aids in this process of chewing and swallowing as a muscular organ. Additionally, the salivary glands in the mouth secrete saliva to help lubricate the food and begin chemical digestion with its digestive enzyme, salivary amylase. Also aiding in chemical digestion in the mouth is mucin. When in the mouth, salivary mucins functions as a protective layer.

The digestive system starts with the mouth and goes all the way down to the rectum. Along the way, your digestive system breaks down the food you eat so you can absorb the nutrients and use them for energy.

In the digestive tracts, the compartments incorporate the mouth and the pharynx. The pharynx then prompts to the throat and to the stomach. Us people have both, a small digestive tract and an internal organ. From the stomach it goes straight into the small digestive tract to process and the internal organ bargains more with waste etc. We likewise contain adornment organs, for example, the liver, which produces bile and the gallbladder, which stores the bile. Bile and pancreatic juice are made and put away in the duodenum. The stomach has three unique tracts with the deepest layer being, the mucosa, submucosa is the following layer created of generally connective tissue and the muscularis which is only a twofold layer of muscles. An extraordinary piece of vitality is utilized as a part of the digestive framework.

Smell that yummy pumpkin pie? Mouth is getting watery. You start to salivate. That is the beginning process of digestion getting you ready to eat that delicious pumpkin pie. That’s why people say digestion starts in your mouth. The digestive tract also known as the alimentary canal, the liver, pancreas, and other abdominal organs make up the digestive system. The esophagus, the stomach, and the intestines, (from the mouth to the anus) all belongs in the alimentary canal. In an adult the whole

The digestive system has a track that is about nine meters long. The ten main organs in this system are the mouth, oesophagus, liver, gallbladder, pancreas, stomach, small intestine, large intestine, rectum, and the anus. Throughout the digestive system food that we eat is broken down, nutrients we need are absorbed from this, and the waste materials left at the end are eliminated.
