Mouth and Teeth The functions of the mouth, with the help of the teeth, work together to digest food. Teeth mechanically breakup food, in order for enzymes and acids to work it’s way through it. The mouth hosts the mechanical breakdown of foods. The salivary glands in the mouth, release an enzyme, called Amylase, which is used to breakdown carbohydrates. The teeth are usually 32 small hard organs, which are designed with the hardest material in your body, enamel, that grind and cut food into small pieces for swallowing. Salivary Glands As you chew, the salivary glandes release a liquid called saliva. Saliva contains mucous which moistens the food and causes less friction when the bolus passes the esophagus and into the stomach and an enzyme, called Amylase, which is used to breakdown carbohydrates.

The tongue forms the masticated food into a ball-like shape called a bolus. The bolus is formed as the tongue moulds the food with the help of the skeletal muscles. The deglutition process happens when the tongue makes rhythmic motions, pushing the bolus to the posterior part of the mouth, for swallowing. Esophagus Esophagus, made from several ring-like structures of strong muscles, performs a milking and squeezing action. This wave-like contraction of the smooth muscles around the tube is called peristalsis, which is how most of the movement in your digestive system is accomplished. This action pulls the bolus down and into your stomach when you swallow. Liver The liver produces bile and secretes it into the small intestine. Bile, an emulsifier, causes large fat globules breakdown into smaller particles. The hepatic ducts in the liver drain bile out of the liver and secretes it into the small intestine is called the common bile duct. Have a variety of metabolic
Crunch, Crunch, Crunch. As you munch on those first few Cheetos the digestion process begins in your mouth. Here, mechanical digestion begins to reduce the size of the Cheeto and mixes the food particles with saliva. The tongue helps mix and move the pieces of Cheeto throughout the mouth. The salivary glands in the mouth also contribute to the breakdown of the Cheetos in the mouth. They secrete amylase and mucus. The parotid glands begin chemical digestion on the Cheetos. It secretes a clear, watery fluid that is high in amylase. The enzyme, amylase, begins to breakdown carbohydrates into disaccharides. The other two salivary glands, the submandibular and the sublingual, secrete saliva containing mucus, which binds and lubricates the Cheeto particles for easy swallowing. Now the food has been formed into a bolus with the help of saliva, the tongue, and teeth. Next the bolus travels into the pharynx, where the epiglottis closes off the top of the trachea so no food can enter. Then it moves on to the esophagus, where peristaltic waves push the food toward the stomach. The food enters the stomach through the cardiac sphincter at the end of the esophagus.
During digestion, the body breaks down food into smaller molecules that could then be used by the body’s cells and tissues in order to perform functions. This starts off in the mouth with the physical movements of chewing and the chemical breakdown by saliva. Enzymes in the stomach break food down further after traveling from the mouth through the esophagus. The food from here then moves into the small intestine, where pancreatic juices and enzymes dissolve proteins, carbohydrates, and fibers, and bile from the liver breaks down fats into these small molecules. Any portion of the fibers or food that were unable to be broken down are passed from the small intestine to the large intestine, which is where the digestive tract transitions into the excretory tract, then the colon and out of the rectum. Any liquids that have been stripped of their nutrients by the body proceed from the stomach to the kidneys. In the kidneys, sodium ions (Na+), uric acid, and urea are exchanged with water, which moves urinary bladder and is excreted through the
Dentistry as a profession over the years has evolved rapidly in light of new scientific evidence. Rapidly evolving science and technology have implemented changes within dentistry as evidenced by new standards and guidelines being produced by nationally recognised associations including National Institute for Health and Clinical Excellence (NICE), Faculty of General Dental Practice (FGDP) and Scottish Intercollegiate Guidelines Network (SIGN) in Scotland, in provision of new scientific evidence. The latest standards and guidelines produced, endorse everyday clinical practice through evidence based dentistry (REF). All dental professionals as part of continued professional development are expected to keep to date on relevant guidelines and knowledge related to their practice (REF). This is supported by the General Dental Council who state all clinicians must maintain their professional knowledge and competence throughout their working career (REF).
In order for this breakdown to happen, the ‘tube’ through which the food travels requires assistance from a number of other digestive organs starting with the salivary glands, and later receiving
Food comes in the mouth, and chewing and saliva start to break it up and make it smaller to swallow. Then, the food goes down through the esophagus to the stomach. Moving of the stomach’s muscular wall keeps going to break down the food. The grinded up food eventually passes
Esophagus: Esophagus is a long straight tube which connects the pharynx to the stomach. Once the food has been reduced to a soft mush, the tongue pushes it to the throat which leads to a long straight tube called esophagus. The esophagus squeezes the mass of food with rhythmic muscle contraction called peristalsis which then forces the food to the stomach.
Mouth- Digestion begins in the mouth. Physical actions, such as chewing, breaks food into small parts so it can be easily digested. Next, salivary glands secrete an enzyme called saliva to mix with food to start the breaking down of carbohydrates (WebMD (2).) From the mouth, food travels to the pharynx, or throat, by swallowing,
Healthcare is a necessity to sustain society. Dentistry is an area of healthcare that I feel extremely passionate about because access to proper dental care is limited, especially in the underserved communities. As an African American, I want to become a dentist and healthcare provider in the hopes of helping patients and adding to the diversification of the field. With a growing minority population in the United States, it has become apparent that there is a shortage of black dentists. This is problematic because underrepresented minorities are in great need of access to culturally connected dentists who understand their clinical needs as much as their lives and their challenges. I believe that when the profession includes a range of ethnicities
...ve eaten, to break down the food into a liquid mixture and to slowly empty that liquid mixture into the small intestine. Once the bolus has entered your stomach it begins to be broken down with the help of the strong muscles and gastric juices which are located in the walls of your stomach. The gastric juices are made up of hydrochloric acid, water, and mucus- and the main enzyme inside of your stomach is what is known as pepsin, which needs to be surrounded in an acidic setting in order to do its job, that is to break down protein. Once the bolus has been inside of your stomach for long enough it begins to form into a liquid called chyme, and what keeps the chyme from flowing back into our esophagus are ring shaped muscles known as sphincters located at the beginnings and ends of the stomach and they have the task of controlling the flow of solids and liquids.
Imagine you are eating a sandwich containing wheat bread, ham, lettuce, and Swiss cheese. Do you ever wonder where the nutrients go from all of the previous listed ingredients? Well, when a bite of this sandwich is taken, the mouth produces a saliva enzyme called amylase. This enzyme immediately goes to work by breaking down the carbohydrates that are in the bread. Once, the bite is completely chewed, the contents then are swallowed and go down the esophagus and begin to head towards the upper esophageal sphincter and the is involuntarily pushed towards the stomach. The next passage for the sandwich is to go through the lower esophageal sphincter; which transports the sandwich into the stomach.
The human digestion system is very complex. It starts with the mouth, salivary glands, pharynx, esophagus, stomach, liver, pancreas, gallbladder, small intestine, large intestine, then ends/exits with the anus. Each step is essential to the whole system. For example, the mouth chews food and mixes it with saliva produced by the salivary glands, and then the pharynx swallows chewed food mixed with saliva, this is followed by the food traveling through the esophagus to the stomach where the food gets a bath and mixes with acids and enzymes. After the stomach, the liver, pancreas, and gallbladder produce, stores, and releases bile and bicarbonates. Bile is produced in the liver and aids in digestion and absorption of fat while the gallbladder stores bile and releases it into the small intestine when needed. Following the process into the small intestine, this is where nutrients will be absorbed into the blood or lymph (most digestion occurs here). Next is the large intestine this is where water and some vitamins and minerals are absorbed. Finally, it is the end of the road, the anus. At...
Introduction: In Canada, general dental health is not part Canada’s national system of health insurance (Medicare) (1) except for some dental surgical procedures that are performed at hospitals. Since Oral health does not come under the Health Act about ninety-five percent of the oral health care services are offered on a fee-for-service basis. Oral health care is under provincial or territorial jurisdiction like other health care services and publically financed dental care programs provide the remaining five percent of oral health care services (2). Thus, majority of Canadians receive oral health via privately owned dental clinics. Privately owned dental care gives these services providers control over dental service charges, types of available treatment for the patients and number of follow-up appointment for treatments or routine care. Service users pay for the dental expenses from their own pockets or utilize insurance coverage (1).
Dental hygiene is a dynamic and challenging career that offers team work, personal growth, and extraordinary benefits, and it is the perfect career for me. As a health care professional, the dental hygienist is an important member of the dental team providing patient care. Good qualities for a dental hygienist are compassion and enjoying talking to people which are two qualities that fit my personality. I love the thought of knowing I made a positive impact in a person's health. Becoming a dental hygienist professionally requires you to obtain an associate degree in dental hygiene. They affect the average American by educating them about dental care. A dentist helps people with their dental health, which can greatly impact a person’s day-to-day life.
The digestive system is a very important system in the human body. It is a group of organs that work together to turn food into energy and nutrients in the entire body. The food that was chewed in a humans’ mouth now passes through a long tube that is inside of the body that is known as the alimentary canal. The alimentary canal is made of the oral cavity, pharynx, esophagus, stomach, small intestines, and large intestines. Those few things are not the only important accessories of the digestive system there is also the teeth, tongue, salivary glands, liver, gallbladder, and pancreas.
Hi there. My name is Albert and this is my adventurous story of my journey through a human. I was a delicious gourmet hamburger with fresh ingredients like salad, mustard and an angus beef pattie. I was dumped into a family feed box labelled with a massive golden arched ‘M’. Now, I’m quite an intelligent burger, unlike my other food companions and I love studying about the fascinating human digestive system when I went to Burgerton College. I’m here to tell you first-hand about my digestive journey into the human body! Here is a map of the human digestive system for your convenience to pinpoint where I am in my journey as I am recounting my story.
