Pharynx: The Epiglottis In The Human Body

Improved Essays
The Alimentary canal or gastrointestinal tract is made up of all the organs which food passes through during digestion. Starting from the mouth, where saliva is produced protecting the teeth and chemically breaking down food molecules and teeth are used to mechanically chew food from larger molecules to smaller molecules. Food is then passed through the Pharynx. The Epiglottis in the Pharynx, is a flap of tissue that covers the trachea to prevent food from entering the lungs, thus directing molecules through the oesophagus. Contractions in the oesophagus transport food into the stomach where gastric juices containing both hydrochloric acid and enzymes break down molecules further. Further contractions move the molecules to the small intestine

    Digestion: Digestive track includes mouth, oesophagus, stomach, intestine and anus. It has two stomachs - The cardiac stomach is where the food is stored, where as the pyloric stomach is where most of the digestion occurs. It churns the food for mechanical digestion and uses digestive glands located either side of the stomach, producing digestive enzymes for chemical digestion. The food then passes through the antennal gland, which is the main excretory organ.…

    The four layers of the digestive tract are mucosa, submucosa, muscularis propria and the adventitia. The mucosa is made up of loose connective tissue and lubricates the passage of food along and protects it from digestive enzymes. The submucosa is a layer of dense irregular connective tissue and supports the mucosa and joins it to the muscular layer. The muscularis propria is made up of smooth muscle tissue and helps with continued peristalsis and the movement of digested material out of and along the gut. The adventitia is composed of loose connective tissue and is coated in mucus to prevent any friction damage from the intestine rubbing against other tissue.…

    The esophagus “ propulsion” located in your throat near your trachea, the esophagus receives food from your mouth when you swallow. Its main effect is to squeeze food along the tract, some mixtures occur as well. The major means of propulsion involves alternating waves of contraction and relaxation of muscles in the organ wall. At either end of the esophagus are ring-shaped muscles (the upper and lower esophageal sphincters), which open and close. The esophageal sphincters normally prevent the contents of the stomach from flowing back into the esophagus or throat.…

    The oral cavity is responsible for the mechanical break-down of food. As food enters the mouth, the teeth begin to chew and the tongue moves the food around. The food particles mix with saliva, which contains digestive enzymes, and becomes slippery. This enables the food to become easier to swallow, allowing it an easier passage as it move into the pharynx, esophagus, stomach, intestines, and finally the colon, which allows it to be evacuated from the body through the rectum. The oral cavity is important to the digestive system because it allows the food to be broken down into smaller pieces in order for it to enter the digestive system easily and allow for the digestive system to process it much easier.…

    The Gastrointestinal System The gastrointestinal tract is a collection of organs that work together to enable the body to digest and absorb numerous substances. It is often described as a long muscular tube starting at the mouth, and ending at the anus. The esophagus, stomach, small intestine (consisting of the duodenum, jejunum, and the ileum), and the large intestine (consisting of the cecum, ascending, transverse, and descending colon, the sigmoid, rectum, and anus), all make up the gastrointestinal tract.…

    Gylys and Wedding (2013, p 122) stated, “that the pharynx serves as a passageway to the respiratory and GI tract and provides a resonating chamber for speech sounds.” In order to keep the respiratory tract free from food particles that pass into the esophagus there is a flap of connective tissue called the epiglottis that shuts the trachea off when we are swallowing to prevent choking. The trachea is the air conducting tube that connects to the lungs in order to breathe. The bolus of food is involuntarily pushed through the esophagus into the stomach by peristaltic contractions made by the muscles.…

    This tube is called the alimentary canal or gastrointestinal tract. There are three main functions to the digestive system. The first is digestion. Digestion is where food is changed in the mouth, stomach, and intestines by chemical, mechanical and physical actions, so the body can absorb it, second is absorption which is where nutrient material is taken into the bloodstream or lymph and travels to all cells of the body. Elimination is the last functions.…

    It is time to begin our tour through our body, and see how the digestive system really works. First the digestive system is broken down into eight sections. Those eight sections are the oral cavity/ tongue, the esophagus, the stomach, the small intestine, the large intestine, the liver, the pancreas, the gallbladder, the rectum, and lastly the anus. Our first stop is the oral cavity or the mouth. The food is taken into the digestive system by the mouth.…

    Stomach When the chewed food has passed from the mouth the esophagus, it reaches the stomach where enzymes peruse the process of breaking down the food into usable substances and forms. The braking down is achieved through stomach acid which is released from the cell lining of the stomach, along with powerful enzymes which help to further break down the food. 4. Small Intestine The contents from the stomach reach the small intestine once they have been sufficiently processed.…

    The two sphincters in the esophagus aid with the entrance of the food bolus and the exit of the food into the stomach. The food bolus enters the stomach where the protein in the turkey and cheese are broken down by pepsin and HCI that break the protein to polypeptides. The fat within the cheese and the turkey and bread are broken down by tributyrinase to tributyrin to glycerol and fatty acids. The stomach issues for the storage, mixing and controlled emptying of food.…

    First step is ingested food is taken into the mouth where it is torn into smaller physical parts by the teeth. The salivary enzymes; amylase and lipase are activated beginning the chemical breakdown of food. Salivary amylase divides starch into smaller glucose molecules. Physically the saliva hydrates and compacts the food for ideal propulsion through the pharynx and esophagus. Propulsion is activated voluntarily when we swallow; the tongue moves towards the hard palate of the mouth thus pushing the food into the pharynx.…

    The mouth which is also called the oral cavity is associated with the accessory organs such as teeth, salivary glands, and tongue. The mouth is where digestion starts. Our teeth are used to chew food into really small pieces and our saliva contains enzymes that begins the process of digestion. Our tongue occupies the floor of the mouth and mixes food with saliva to form bolus which is a compact mass that forms food into a lump that helps initiates swallowing. The mouth begins the process of swallowing which carries food through the pharynx and into the esophagus.…

    This opening allows chyme to enter into the small intestine. The small intestine is composed of 3 parts: duodenum, jejunum and ileum. The duodenum is the only part of the small intestine that continues to break down food with the release of bile. While the stomach releases hydrochloric acid and creates an acidic environment with a low pH, the duodenum is slightly basic with a higher pH. Bile, which is produced in the liver and stored in large quantities in the gall bladder, is released to emulsify and breakdown fats at this point. For the remainder of the time in the small intestine, food passes by peristalsis and comes into contact with millions of villi.…
