Digestive System Essay

Digestive System After dissecting the rat, we learned that the rat’s body has many complex systems. To begin, the digestive system contains a group of organs that work together to convert food taken in from the body and converts it to energy and basic nutrients to feed the cells in the body. The digestive system includes the mouth, pyloric valve or sphincter, caecum, small intestine, colon (large intestine), duodenum, retrum, and stomach. The salivary glands, liver, and pancreas are glands that

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

The digestive system has the function of digestion and absorption. This means that the digestive system breaks down food into small molecules that will be absorbed and used by the body. But this process can only be completed with the help of multiple organs – the esophagus, the stomach, and the colon, to name a few. First is the mouth, where the salivary glands, tongue, and teeth are located (fig 2). The salivary glands produce saliva, which helps break down food. The teeth cut and grind the food

When choosing between what system to write about, I thought the digestive system would be a good topic because food is probably one of my favorite things, not only cause it tastes good but because it gives me the energy to do all the things I need to do throughout the day. We talked in class about how you should always get the nutrients from food and never from supplements, which I’ve always tried to do. So, what is the digestive system? The digestive system is an assortment of organs that performs

The Digestive system: The stomach related framework is comprised of the gastrointestinal (GI) tract—likewise called the stomach related tract—and the liver, pancreas, and gallbladder. The GI tract is a progression of empty organs participated in a long, bending tube from the mouth to the butt. The empty organs that make up the GI tract are the mouth, throat, stomach, small digestive system, internal organ—which incorporates the rectum—and butt. Sustenance enters the mouth and goes to the rear-end

The Digestive System The premise of the digestive system is to turn food into energy and get rid of waste. This system has two main functions, digestion and absorption. One of the system’s major parts is called the digestive tract or alimentary canal. The digestive tract is an ongoing tube that has two openings. One opening is the mouth and the other aperture is the anus. The alimentary canal consists of the mouth, pharynx, esophagus, stomach, small intestine, and large intestine. This canal also

What the digestive system does The digestive system is when the body does to break down food. Firstly, it enters the mouth and is broken down by the teeth of the animal and saliva. Then it travels along the oesophagus to the stomach. Then in the stomach for further breaking down, it is broken down by hydrochloric acid and enzymes. The acid breaks down bacteria and the food material into smaller molecules. Once this is complete it then moves onto the small intestine. Enzymes are secreted from the

Nutrition BIO-151 Chapter 3 Digestion Cheyenne De Jong October 8, 2017 The digestive system is a group of organs that work together. It is responsible for taking whole foods and turning them into energy and nutrients to allow the body to function, grow and repair itself. Today, I will explain how the digestive system performs this unique process. I’m having a loaded tuna sandwich with lettuce, tomato, cheese and mayonnaise. The bread of my sandwich is mostly carbohydrates. Carbs are the sugars

Functions There are 3 functions of the digestive system: food is broken down, nutrients are absorbed, and waste is eliminated. The food is broken down by chemical digestion (food is broken down by enzymes) and mechanical digestion (food is physically broken down). The nutrients are absorbed in the small intestine. Solid wastes are eliminated by being turned into feces (poop) and then exiting through the anus. The digestion process begins in the mouth. The mechanical digestion occurring in the mouth

The digestive system is a severely underrated part of the human body. For most people, the digestive system is just something that gives them diarrhea after they eat poorly. Little do they know, that the digestive system is the key part to fueling our bodies. The digestive system is how you break down and absorb much needed nutrients. This is how we “fuel” our body. Our body breaks down the food we eat into manageable pieces, and then we are able to absorb it into our bloodstream so that it can be

The Digestive System 1.1 The digestive system is comprised of a group of organs known as the alimentary canal, which is one continues tube that runs from the oral cavity to the anus. The second set of organs that make up the digestive system are the Accessory organs. The digestive system has six main functions: ingestion, secretion, mixing and movement, digestion, absorption, and excretion of food (Tortora & Derrickson, 2009). Alimentary canal Organ Structure Function Diagram Mouth The mouth is made

down. Pepsin (an enzyme) breaks down proteins and hydrochloric acid to break down solid food. Food can spend up to 15 minutes to 24 hours in the stomach, depending on the size of meal. Surprisingly the stomach of a horse only takes up 10% of the digestive system. Because of how small it is the horse must eat little and often. After the food has gone through the stomach, it moves onto the small intestine. Food moves through it between 30 minutes to an hour. It is made up of three parts. The Duodenum

The Digestive System What are the main functions in digestion of the a) mouth b) stomach c) small intestine The mouth takes in the food and uses the teeth and the salivary glands do break down the food so it could move onto the next phase. The teeth chew food while the salivary glands, liver, bile duct and pancreas produce digestive juices to break down food. The stomach is a L shaped, organ situated on the left side of the abdominal cavity beneath

The digestive system is the process of turning food that we eat into nutrients that the body uses for energy. This system also creates waste that the body needs to eliminate. We are now going to talk about the journey of food through the digestive system to see how everything works together to reserve the nutrients of the food we take in everyday and how the body removes all the remaining substances from our body. As I enter the mouth, there is already I liquid that the salivary glands have produced

Human Digestive System Single-celled organisms can directly take in nutrients from their outside environment. Multi-cellular animals, with most of their cells removed from contact directly with the outside environment, have developed specialized structures for obtaining and breaking down their food. The human digestive system is a complex series of organs and glands that processes food. It is a coiled, muscular tube (6-9 meters long when fully extended) extending from the mouth to the

Andres Nogales Professor Dr. Felton Essay 1: Since this student had a bag of chips which is carbs and turkey sandwich which is considered protein and fat and water. The first stage in the digestive system is ingestion when the student enters his lunch in their mouth. In this stage there is mechanical and chemical digestion taken place. The mechanical digestion is take place by biting and tearing the food into smaller parts which would then be known as bolus. Chemical digestion is occurred when

Confirm Physical Health Status. The Digestive System Parts of the Digestive System (https://www.thinglink.com/scene/496007041890910209) The digestive system comprises of multiple organs like the mouth, which consists of the salivary glands, saliva, tongue and epiglottis; the Pharynx, Oesophagus, Diaphragm, Stomach, Spleen, Liver, Pancreas and the Lower gastrointestinal tract which includes the small and large intestine and the caecum. The major role of this system like it suggests is to digest food

Anatomy and Physiology of the Digestive System Mouth and Salivary Glands The mouth, also referred to as the oral cavity, is the entryway into the digestive tract. The opening is formed by the lips, which guide food into and contain food in the mouth. The palate forms the roof of the mouth and separates the mouth from the nasal passages. The uvula is important in sealing off the nasal passages during swallowing. The tongue forms the floor of the mouth and guides food within the mouth during

Gabe Menuel. 8H What does a digestive system do in a human? A digestive system in a Human is designed to help the human process food into energy and nutrients which are utilised by various systems in the body. The energy and nutrients are used to power and sustain the human being. The digestive system consists of the gastrointestinal tract and other organs such as the liver, pancreas, and gallbladder. The GI tract has organs joined in a long tube from mouth to anus. There are hollow organs
