The Digestive System : Main And Accessive System

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.

1. Oral cavity, pharynx, (must also include accessory organs such as salivary glands, tongue, and teeth)

Chapter 9: Gastrointestinal System The gastrointestinal system is essentially a long tube running from the mouth to the anus. It serves as the primary source nutrients to the body as it breaks down and digest all of the food consumed by the body before excreting it. The gastrointestinal system contains the mouth, teeth, esophagus, slower esophageal sphincter, stomach, pyloric sphincter, small intestine, ileocecal valve, appendix, large intestine, rectum, and anus.

In the digestive tracts, the compartments incorporate the mouth and the pharynx. The pharynx then prompts to the throat and to the stomach. Us people have both, a small digestive tract and an internal organ. From the stomach it goes straight into the small digestive tract to process and the internal organ bargains more with waste etc. We likewise contain adornment organs, for example, the liver, which produces bile and the gallbladder, which stores the bile. Bile and pancreatic juice are made and put away in the duodenum. The stomach has three unique tracts with the deepest layer being, the mucosa, submucosa is the following layer created of generally connective tissue and the muscularis which is only a twofold layer of muscles. An extraordinary piece of vitality is utilized as a part of the digestive framework.

Consist of oral cavity, esophagus, gallbladder, liver, stomach, duodenum, pancreas, colon, cecum, appendix, jejunum, and rectum.

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.

We start with the mouth, in the feature, I am chewing on a bit of bread from a sandwich, the sandwich softens up two distinct ways, mechanical and concoction absorption. Mechanically, teeth are utilized to bite sustenance into little pieces and blend it with salivation with the tongue's assistance. The tongue then sends this pounded up sandwich down the throat to the stomach. Synthetically, Salivary organs in the mouth produce spit, containing the protein amylase to separate starch, is blended with sustenance, making it gentler and smoother prepared for its adventure down to the stomach.

Main components in the digestive system include the teeth, tongue, salivary glands, liver, small intestine, stomach, and pancreas..The function is to digest food.

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

First steps in the digestive system take place in the mouth, including our lips without them food and saliva would just fall out and it would be very disgusting. As the teeth cut, tear, and grind the food down into small, teeny-tiny pieces so that it can fit down the throat, which then will continue throughout the digestive system. Without our teeth we would simply choke on all of our food constantly and would not survive. There are several types of teeth in the ordinary human mouth,usually in a full set of permanent teeth there are in total thirty-two teeth. The different types of teeth do different things, Like the incisors that are adapted for cutting. Like when you are chewing let 's say some chicken these help to cut the chicken up into smaller bits.The eye-teeth or Canines are used mostly for piercing the food. The premolars and Molars have a broader shape and are used to grind and really break up the chicken that you are eating. Some people without teeth often get their food blended or eat soft foods that can go down quickly and easily.

Name and locate the three sets of salivary glands in humans, name and describe the secretions from these glands, and name the two types of cells that compose these glands. three sets of salivary glands: parotid = largest; lies over masseter, submandibular = floor of mouth; lateral, sublingual = floor of mouth, medial. The two types of cells that compose these glands are: mucous cells secretes mucus; serous cells secretes watery substance containing the enzyme salivary amylase

The three accessory organs of the digestive tract are the; liver, gallbladder and pancreas. The function of the liver includes receiving blood from both arterial and venous sources. Also, the liver secrets bile to assist with intestinal digestion. In addition, the liver metabolizes fats, proteins and carbohydrates. In addition, the liver is responsible for bile salts that help with intestinal emulsification and the absorption of fats. Also, the liver produces bilirubin. Furthermore, the liver is responsible for; contraction, energy, fluid balance, protection, regulation, structure and transport. The gallbladder stores bile and then concentrates it between meals. Moreover, the bile helps to digest fats. Furthermore, the pancreas produces digestive

The major stages of the digestive system are ingestion, digestion, absorption, and elimination. Ingestion is the process of taking in food and water into the form of swallowing, and digestions is when the food that was consumed begins to breakdown into smaller pieces so it’s easy to be absorbed into the body. Digestion can happen with two phases, when the food is breakdown by teeth and the second phase which is the chemical breakdown, which is the breakdown of food by enzymes. The next stage of the digestive system is absorption, which absorbs the food of the digestions. The nutrients such as amino acids and simple sugars travel in the blood when then goes to the body cells, that can be broken down more or used to build a cell’s large molecule.

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

Digestive or gastrointestinal system (GIS) - Accessory organs of the digestive system include the teeth, tongue, saliva glands, liver gallbladder and pancreas. To achieve the goal of providing nutrients to the body, major functions take place in digestive system which are; Ingestion, Digestion, Absorption and Excretion.
