...affect the amount of time it takes for foods to travel through the digestive tract, and how does digestion occur in each part of the digestion system, how proteins, fats, and carbohydrates break down in the digestive system, and what types of food help with digestion; I'm going to first tell you what the digestion system is and what it is made up of. Per the NDDIC (National Digestive Disease Information Clearinghouse), "Digestion works by moving food through the GI tract. Digestion begins in the mouth with chewing and ends in the small intestine. As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules. The body then absorbs these smaller molecules through the walls of the small intestine into the bloodstream, which delivers them to the rest of the body. Waste products of digestion pass through the large intestine and out of the body as a solid matter called stool". (NIH Publication No. 13-2681, 2013). Knowing all of that now I can tell you more about the digestion system. You may be wondering how long does it take for food to pass through your GI track; well let's just say it's up to your body on how fast it wants' to pass the intake through. Having knowledge from working in Colon and Rectal Surgery it overall take the normal person anywhere from one to three days to have the food past through their GI track; it depends on how much fiber is in the food that they ingest. As stated above digestion...

...function(s) of the digestive system (2.5 pts). The major function of the digestive system is to break down food stuffs for the purpose of extracting essential nutrients, building block molecules, and water (Freeman, 856). 2. Briefly, explain the major function(s) of the cardiovascular system (2.5 pts). The major function of the cardiovascular system is to facilitate the exchange of O2 and CO2 between tissue and the environment as well as the transport of vital molecules and nutrients to all tissues (Freeman, 875). 3. Using all relevant organs and anatomical structures, trace the physical connection between the digestive and cardiovascular systems (3 pts). Once food has emptied into the stomach, secretory enzymes are released that provoke the secretion of pancreatic enzymes as well as bile. Bile emulsifies fat globules which are converted into chylomicrons; these are then absorbed into lacteals for further processing in the lymphatic system before proceeding to final processing...

...microns long and traveling through the human body. Today we will be swallowed by a 55 year old man, Mr. Smith, who is currently eating a hamburger, French fries, and enjoying a nice cold root beer. Our goal today is to monitor the digestion of Mr. Smith’s meal through the gastrointestinal tract. As we progress through the body, I will be describing all the major structures that we go through as well as describing what happens to the meal as it goes through the digestion process. Let’s get started. We are going to begin our journey by watching how the food is digested via the gastrointestinal pathway and the urinary pathway. Starting with the digestive system, the food will begin to be digested in the mouth where food is acted upon by saliva and enzymes like amylase (WiseGeek, Digestive System, 2012). The brain has a reflex that triggers the flow of saliva into our mouths when we see or even think of food (WiseGeek, Digestive System, 2012). There are three major salivary glands that are involved in this process: the parotid, submandibular, and sublingual glands. These glands function to secrete saliva into our mouths in order to keep it moist, lubricate and bind our food to begin the digestion process, and to maintain oral hygiene (WiseGeek, Salivary Glands, 2012). Our saliva moistens the food while our teeth chew it up and make it easier for us to swallow. As Mr. Smith swallows his food, the muscles in his tongue and mouth will move the food into his pharynx. The pharynx...

...P4- Explain the physiology of two named body systems in relation to energy metabolism in the body In this assignment I will be explain the physiology of two named body system in relation to energy metabolism in the body. The system that I have chosen is the respiratory system and the digestive system. The respiratory system is where the exchange of gases in the body this is where the oxygen enters into the blood. The lung is the main organ which the lungs intakes oxygen into the body and the carbon dioxide is exported out. The respiration system is made up of many organs which help us to breathe properly. The digestive system is where the organs inside the body break down the food and convert it to energy and nutrients that are needed in the body. The stomach is a tube shaped which has all the food and liquid that we have ate and it makes around the body and it is a mainly long twisted tube that starts from the mouth and comes all the way down to the anus and into few organs such as the pancreas and the liver which stores any chemicals accessible. The metabolic rate...

...The Digestive System and Its Activities What happens to food when it is ingested? To understand this process it is important to know how the digestive system works and its components. The digestive system is more than just the stomach and colon, rather it is a system of organs working together to break down food into “nutrient molecules, absorbing these molecules into the bloodstream, and ridding the body of the indigestible remains” (Elaine and Katja 849). The digestive system is composed of the alimentary canal, also known as the gastrointestinal tract, and its accessory digestive organs. The alimentary canal “is a muscular tube lined with epithelium [tissue] and adapted regionally to the various functions of the digestive organs” (Fritsch and Wolfgang 42). It includes the mouth, pharynx, esophagus, stomach, small intestine, and large intestine. It is in the alimentary canal where food is broken down to smaller fragments and absorbed by the bloodstream. The teeth, tongue in the mouth; and the gallbladder, salivary glands, liver, and pancreas connected by ducts to the GI tract make up the accessory digestive organs. These accessory organs release or store special secretions that aid in digestive and absorptive processes. The mouth is the entryway to the alimentary canal. In depth, the mouth, or oral cavity, is bordered by lips, cheeks, palate, and tongue. When opened anteriorly it is called the oral orifice. The mouth region contains thick stratified squamous epithelium...

...Human digestive system In the human digestive system, the process of digestion has many stages, the first of which starts in the mouth (oral cavity). Digestion involves the breakdown of food into smaller and smaller components which can be absorbed and assimilated into the body. The secretion of saliva helps to produce a bolus which can be swallowed in the oesophagus to pass down into the stomach. Saliva also contains a catalytic enzyme called amylase which starts to act on food in the mouth. Digestion is helped by the mastication of food by the teeth and also by the muscular contractions of peristalsis. Gastric juice in the stomach is essential for the continuation of digestion as is the production of mucus in the stomach. Peristalsis is the rhythmic contraction of muscles that starts along the wall of the stomach. This initially results in the production of chyme which when fully broken down in the small intestine is absorbed into theblood. Most of the digestion of food takes place in the small intestine. Water and some minerals are reabsorbed back into the blood, in the colon of the large intestine. The waste products of digestion are defecated from the anus via the rectum.

...The structure and function of the digestive system Your digestive system is made to perform its special function of turning food into the energy you need to survive and packaging the residue for waste disposal. To help you understand how the many parts of the digestive system work together, here is an overview of the structure and function of this challenging system. Mouth The mouth is the beginning of the digestive tract; and, in fact, digestion starts here when taking the first bite of food. Chewing breaks the food into pieces that are more easily digested, while saliva mixes with food to begin the process of breaking it down into a form your body can absorb and use. Esophagus Located in your throat near your trachea (windpipe), the esophagus receives food from your mouth when you swallow. By means of a series of muscular contractions called peristalsis, the esophagus delivers food to your stomach. Stomach The stomach is a hollow organ, or "container," that holds food while it is being mixed with enzymes that continue the process of breaking down food into a usable form. Cells in the lining of the stomach secrete strong acid and powerful enzymes that are responsible for the breakdown process. When the contents of the stomach are sufficiently processed, they are released into the small intestine. Small intestine the small intestine is made up of three segments — the duodenum, jejunum, and ileum — the small intestine is a 22-foot long muscular tube that breaks down...

...Khalia Roche Professor Wolfson BIOL 111 The Digestive System and Ulcerative Colitis The Digestive System is one of the most important systems of the human body. The purpose of the digestive system is to process all foods that enter through the mouth. The foods and liquids must be processed until small enough to be absorbed and used by the cells of the body (National Institute of Health). According to WebMD, “the digestive tract, also known as the gastrointestinal (GI) tract, consists of a long, twisting tube that reaches from the mouth to the anus.” It includes several organs: the mouth, pharynx, esophagus, stomach, small intestine, and large intestine (National Institute of Health). There are also other major accessory organs included in the digestion process which are: the salivary glands, liver, gallbladder, and the pancreas. These organs secrete fluids needed during the digestive process (National Institute of Health). Food undergoes three processes while in the digestive system: Digestion, Absorption, and Elimination. Digestion is an intricate process where the food that is ingested is turned into nutrients, which the body uses for energy, growth and cell repair (WebMD). There are two types of digestion: mechanical digestion and chemical digestion. Mechanical digestion involves the breakdown of larger food portions and is acted upon by thousands of enzymes. This digestion begins with the mouth and continues in the stomach (National Institute of Health). The second...

...In this assignment I will be addressing how the digestive system and the respiratory are linked to energy metabolism in the body. I am addressing this to explain what the energy system is and how it functions the only way I can describe it is through explain the digestive, respiratory and cardiovascular system work and how they link together. This topic is really important as without energy we would be able to function or survive. There are 3 body systems involved with energy. The first system is the digestive system, the teeth mash up the food which is moisturised by the saliva then your tongue sends the mashed up food down your throat. The pharynx then sends the food to the esophagus which is connected to the stomach .Your stomach then mixes your foods together breaking it all down into tiny pieces then mixes an acid called hydrochloric acid which kills all the bacteria, the stomach then uses its muscles to flip the food around breaking the food into smaller particles. The small intestines is where the most digestion occurs after the food leaves the small intestine 90% of all the nutrients have been extracted from the food that entered it, the small dissolvable molecules are ready to be absorbed into the blood stream and taken to the cells and tissues where they are needed. We also use the respiratory system to create energy. The respiratory system starts off at the mouth and nose it then travels to the pharynx and then to the trachea (windpipe) where it goes down the bronchi...

...Let’s follow the path of a delicious ham and cheese sandwich with lettuce and pickles as it is eaten and digested! Start at the beginning and discuss the anatomical parts as well as the biochemical roles that contribute to this sandwich being turned into chemical energy. Be sure to include mechanical and chemical mechanisms, along with how they are metabolized in the body! Digestion is the chemical breakdown of food molecules into smaller molecules that can be used by various cells within the body. The breakdown is initiated when food is ingested in the mouth and specific enzymes are exposed to components within the food molecules. Digestion begins in the mouth with mastication, or chewing, performed by the teeth. The purpose of chewing is to grant the food more exposure to enzymes, therefore allowing chemical digestion to occur faster. The presence of the food in the mouth stimulates exocrine glands. This causes the mouth to secrete digestive enzymes, namely salivary amylase. These secreted enzymes aid in the breakdown of foods, officially starting the digestion process. Carbohydrates in particular are mostly broken down by salivary amylase. Salivary amylase breaks starch, a popular carb, down to maltose. This means that the bread of the ham and cheese sandwich will notably be chemically altered at this point. It is because of this that bread begins to taste somewhat sweet if it is held in the mouth for some time. Muncins, or mucous, found within saliva help hold the food...

...FALL 2015 1. Explain the functions of each system of the body: digestive, cardiovascular (respiratory and circulatory), immune, skeletal/muscular, endocrine, reproductive, and nervous. Digestive breaks down food for enery. 2. Compare and contrast how positive and negative feedback mechanisms are used to maintain homeostasis. Use these concepts to describe: * The maintenance of blood glucose levels When there is too much glucose in the body, insulin us used to bring it back to the normal level. This uses negative feedback because it is bringing the blood glucose levels back to normal. * The release of platelets to form blood clots. The first platelets will bind to the area of the wound and will release a signal that recruits more platelets tot come to the site. This is an example of positive feedback- the output enhances or exaggerates the original stimulus. 3. What does it mean if an organism is an ectotherm? Endotherm? Give an example of each. An ectotherm does not regulate its own temp and depend on the envirmental temp. and endortherm can control its temp. 4. Herbivorous mammals tend to have extremely long digestive systems, especially the intestines; omnivores have intermediate length intestines; and carnivores have extremely short intestines. What might be a logical explanation for this pattern? It takes longer to digest plants because of the cell wall. Thus there needs to be a longer digestive tracks so that herbivores can get all the nutrients...

...paper, chemistry can be seen everywhere. However, most people mistook the power of chemistry in our own bodies. How is it that a simple slice of bread, once consumed, can turn into fuel for the human body? Using the digestive system and its many organs through the process of digestion and metabolism is how our bodies receive the energy it needs to continue on throughout the day and the rest of our lives. Chemistry then kicks in as food starts its process from entering to leaving the body, through the rate of our metabolism, and also by the transfer of energy. The chemistry in the digestive system is a very important process, because without it there would be no human life. Compared to all other systems in the body, the digestive system is one of the most diverse and important. According to Robert Sullivan the digestive system is a set group of organs whose function is based on the process of turning food, absorbing nutrients for energy and getting rid of the bodies waste (Sullivan, 2008, p.33). The organs that are in the digestive system are the following: esophagus, stomach, small intestine, pancreas, liver, gallbladder, colon or large intestine, rectum and anus (Ballard, 2003). Imagine eating a nice dinner with delicious smelling food. Now, imagine eating the food. Have you ever wondered where your food has gone once you consume it?
