The digestive and excretory systems help the body with the wonderful task of food. The digestive system is composed of the stomach, mouth, liver, pancreas, and the large and small intestine. It digests food and provides the
Colon and rectum are both located in the digestive system. There are two parts of the digestive system. Upper part of the digestive system included stomach and small intestine, in which their job is to digest food for energy. Lower part of the digestive system are called gastrointestinal system, where colon and rectum are located. Its function is to absorb fluid to form solid waste then passes from the body as a stool. Small intestine made up of the most part of the digestive system, it is about 20 feet long. It break down the foods and absorb most of the nutrients. Then it pass to the large intestine which is mainly made up of a muscular tube, colon, and it is about 5 feet long. The colon can be divided into 4 section. Ascending colon, it is the beginning of the colon that included the cecum, where the appendix attaches to the colon. Transverse colon, the second section of the colon. It located in the upper abdomen and from the right to the left. The next section is called descending colon, the lower abdomen and from the left to right. The last section,
Our mouth, esophagus, stomach, pancreas, liver, gallbladder, large intestine, small intestine, rectum, and anus come together to form the digestive system which breaks down our food into simpler molecules. The food enters through the mouth, travels down the esophagus, breaks down in the stomach, pancreas, liver, and gallbladder and then moves through the intestines down to the rectum and anus. A pig’s digestive system is no different than a human’s. A foregut, midgut, hindgut, and a digestive gland form the digestive system of a crayfish. The foregut contains the stomach (partially breaks the food down), the
The digestive system is made up of all different organs which starts at the mouth and finishes at the anus but on the way involves all other organs; these organs help to break down and absorb the food.
The digestive system is a group of organs working together to convert food into energy and basic nutrients to feed the whole body. To achieve the goal of providing energy and nutrients to the body, six processes take place in the digestive system.
Food is digested by being broken down, by a variety of enzymes, into useful nutrients, which are transported around the body to places where they can be of use, and into waste products, which are excreted from the body. The digestive system is made up of a number of organs, oesophagus, stomach, liver, pancreas, gallbladder, and small and large intestines, these are then separated into the digestive tract and the digestive organs. The digestive tract is, essentially, a single continuous tube that begins at the mouth and ends at the anus, in a fully grown adult it is approximately seven metres long. Food travels through the digestive tract and the digestive organs produce the enzymes and chemicals that are responsible for
The digestive system is the process that involves the mouth, esophagus, stomach, small intestine, large intestine and rectum. For the body to function, the body`s cells needs energy and that energy will come from the food we eat. All the food we eat contains nutrients, carbohydrates, glucose, lipids, protein and many more other substances. The only way the body can absorb and convert these nutrients into energy to our cells is through breaking down the large molecules into smaller pieces and moist by the action of enzymes.
The digestive system helps the humans break down food and turn it into nutrients. The digestive system is made up of a lot of different organs such as salivary glands, pharynx, mouth, esophagus, stomach, liver, gallbladder, small intestine, large intestine, and pancreas. Salivary glands produce saliva, which keeps the mouth and other parts of the digestive system moist. The pharynx role in the digestive system is to connect the nose and mouth to the esophagus. The mouth is used for putting in food and also eating the food. The esophagus has only one function and it is to carry food, saliva, and liquid. The stomach receives the food from the esophagus and secretes acid and enzymes that digest food. The liver regulates the composition of blood,
The digestive system has many functions that allow people to live out their daily lives including the production of energy through nutrients in a functioning digestive system. The first function of the digestive system is the ingestion process. Ingestion is the intake of food performed by the mouth. Then, the mouth and stomach are responsible for storing the food until digestion. After ingestion, the digestive system secretes fluids, in order to soften the food and protect and lubricate internal organs, through a means called secretion. The food is then sent through a procedure of mixing and movement. Mixing and movement move the food to the intestines for digestion. Digestion is the most known function of the digestive system. Food is turned into chemicals and broken down into building blocks. When the digestive system has its building blocks, absorption takes place in the small intestines. The small intestine contains microscopic blood and lymphatic cells which carry the chemicals all over the human body. Once the chemicals are dispersed, the final process of the digestive system takes place. The overall progression is called excretion. Defecation is the process within excretion. Defecation takes indigestible substances from the body, so it
The digestive system contains nutrients, water, and electrolytes that the body needs to maintain a healthy lifestyle. “The organs of this system ingest, and absorb food and eliminate the undigested remains as feces” (Human Anatomy and Physiology, 2012). The process of the digestive system first starts by eating food through the mouth. After the food has been eaten, it then breaks down into subunits, process called digestion. Next is the movement of the food along the GI tract so all functions can be fulfilled. Then the absorption of the nutrients in the GI tract are delivered to cells through the blood. The elimination of indigestible molecules is the last step in the process. The alimentary canal walls have four tunics (layers). “Each of these tunics has a predominant tissue type and a specific function in the digestive process” (Human Anatomy and Physiology, 2012). The mucosa is the innermost layer and is a “wet epithelial membrane abutting the alimentary canal lumen” (Human Anatomy and Physiology, 2012). The mucous membrane “consists of a surface epithelium, a lamina propia, and a muscularis mucosa” (Human Anatomy and Physiology, 2012). The
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.
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
