How Digestive System Works

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.

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 are laid outside of the digestive system, but they are associated with contributing to the system’s function. The mouth processes the food so that it is easier to swallow. From the mouth, it moves to the back of the mouth.

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.

In the small intestine there are three segments that are called the duodenum, jejunum, and the ileum. The small intestine continues to break the food down. It does this by creating enzymes that are released by the pancreas. Bile from the liver helps in digestion of fat and it also eliminates waste. Next step in the digestion is the liver. There are also other things at work in the liver such as peristalsis. Peristalsis is when food moves through and mixes up in the digestive secretions. The functions of the duodenum is that it continues the process of breaking down food. The jejunum and ileum are responsible for the absorption of nutrients into the bloodstream. There are also three organs that have a major function in helping the stomach and small intestine to digest food. The pancreas helps digestion by releasing enzymes that the pancreas releases help break down protein, fat, and carbohydrates from what is eaten. The liver’s two main functions are to make and release bile and also to clean and purify the blood, that as came from the small intestine that is containing nutrients that was just

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 into smaller particles, with the help of the saliva the salivary glands produce. In addition, the tongue assists the teeth in this process by combing the food and the saliva. Then, the tongue moves the food along to the pharynx and esophagus. Located deep to the tongue, the pharynx allows the swallowed food and drink pass to the esophagus (fig 2). The epiglottis prevents us from choking, as it is located just under the pharynx (fig 2). Moreover, the epiglottis ensures that the swallowed substances do not interrupt the gases oxygen and carbon dioxide from reaching the lungs. Then there is the esophagus, which is inferior to the epiglottis (fig 4). The esophagus is a passageway that connects the pharynx to the stomach. Together, the pharynx, epiglottis, and esophagus ensure that food does not take the wrong path – down the trachea into the lungs – and does enter the stomach. The esophageal sphincter is deep to the esophagus (fig 4), and is used during eating, burping, breathing, and

The digestive system is very important in digesting food and breaking it down so it can be digested easily. The digestive system turns food into energy. Throughout the process there are nutrients which are absorbed. There are many things that contributed to the digestive system such as the mouth which produces saliva which helps to break down food and nutrients such as carbohydrates with the help of an enzyme called amylase. The major food groups which are called macro nutrients include carbohydrates, proteins and fats. All of these nutrients play an important role in the body. There are also many micro-nutrients which include vitamins and minerals which provide the body with health and well-being. The digestive system is made up of the mouth, which includes the teeth (the teeth are used to cut and grind food into smaller pieces, they contain blood vessels and nerves), tongue (the tongue is a muscle that has a rough surface including the taste buds), salvia glands (they produce salvia which moistens the food to make is easier to digest), the pharynx (this helps the food travel to the stomach, the pharynx also plays an important role in the respiratory system. It also contains 2 different flaps to separate the 2 functions), esophagus (this connects the pharynx to the stomach and transports chewed food to the stomach), stomach (this is a muscle that is

The proses of the digestive tract are very complex and difficult to understand. There is a lot of chemistry that ties into the digestion system. There is multiple part of the digestive tract that all have different role helping the body to digestive nurturance. Most people when asked think that the stomach is the place where it all starts but they would be wrong. People also think the that the stomach is the most important but if it comes down to it that with out any part of this complex system the digestion could not take place.

The digestive system is a group of organs working together to convert food into energy. The food digested is also tied into basic nutrients to feed the body. The digestive system is something called the tube within a tube. This is because it is a hollow structure with two openings that run the height of your body. The digestive tract consists of two parts the gastrointestinal tract known as GI tract and a set of accessory organs. GI tract starting at the oral cavity, through abdominal cavity and end at the anus. Major accessory organs include pancreas, liver, and gallbladder. There are 5 basic processes the digestive system have. The processes include and ingestion, mixing digestion, absorption, and defecation. Ingestion is the first step which is when the food and liquids are taken in the mouth and eaten. Mixing is when the smooth muscles in the walls of the GI tract mixes the food and send it through the tract. Next is digestion where the food is broken down by mechanical and chemical processes. Absorption is the epithelial

The digestive system breaks down food particles so they are easier to digest. The large intestine(Number) helps break down food. The large intestine has a layer of mucus to make sure no acid makes holes through the large intestine. The small intestine (number) helps break down food with enzymes to lead to the anus.

The digestive system is made up of the gastrointestinal (GI) tract—also called the digestive tract—and the liver, pancreas, and gallbladder. The GI tract is a series of hollow organs joined in a long, twisting tube from the mouth to the anus. The hollow organs that make up the GI tract are the mouth, esophagus, stomach, small intestine, large intestine—which includes the rectum—and anus. Food enters the

Digestion, how you get your energy and nutrients, seems simple. However, it is actually a complex process involving three organ systems and many stages.

THe digestive system is the system that breaks down what one eats into the nutrients the body needs to function properly. It also takes the parts the body does not need and eliminates it from the body. There are three major functions of the digestive system (Coolidge-Stolz et al 60). First, the food one eats is broken down into molecules that the body can use and turns the other parts into waste. Next, the useful molecules are absorbed into the blood and carried throughout the body. Lastly, the waste, or parts the body doesn’t need is eliminated from the body (Coolidge-Stolz et al 60). The digestive system has many parts. Some of these are the mouth, salivary gland, epiglottis, esophagus, liver, stomach, gallbladder, pancreas, large and small intestine, and the rectum. The digestive process starts in the mouth. The salivary glands release saliva that assist the teeth in breaking down food (Coolidge-Stolz et al 60). After chewing is done, one swallows and the food particles and it goes down the esophagus. Before it goes down the esophagus, the epiglottis closes so no food goes down the windpipe.The epiglottis is a tiny flap of

Once food leaves the mouth, it travels down the oesophagus and into the second cavity the stomach. Here digestives enzymes are released such as hydrochloric acid and gastric

In the mouth, the saliva acts to break down carbohydrates. Which enzyme comes by and helps but is also called a amylase. The esophagus is a tube that controls the muscles and the autonomic nerves, and helps food to travel through the mouth to the stomach. The mouth contains coats of the food that mixture the acid of the digestive enzymes to help break the food down, and another layer of mucous
