The Digestive System : Main And Accessive System

The 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, where food enters through the mouth, digestion where food is broken down physically and chemically, absorption where nutrients are taken to their desired organ for use in the body, and elimination where waste is removed from the body due to being useless or toxic.When it comes to the human body there are plenty of components that we take for granted. Think about it, when was the last time you dwelled upon the function of your saliva or pondered on the responsibility of the esophagus? If you are like me, the answer to the question is simple, never. It is because our body is one of the greatest and yet most underappreciated machinery known to man. Within that system, which tends to get a lack of appreciation, stands alone one main process that we utilize on a daily basis and rarely give credence to its importance. This process is known as digestion, which occurs in the alimentary canal also known as the digestive system. The digestive system consists of 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.

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

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

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

All cells need nutrient and energy to live and this energy provided by processes that called digestion. For example, when we eat some things like bread, meat, and vegetable, although they are delicious, but they are not forms of nourishment for the cells, therefore they need to change into an acceptable form such as smaller molecules to absorb by blood and carry to body cells. Digestion is break downing of food into appropriate form to absorb into the bloodstream. Digestion system contains the digestive tract called alimentary canal and associated glands that secrete digestive juices for digestion of food. The digestion or breakdown is started when food is taken in the mouth and mastication performed by the teeth and exposed to certain enzymes. The primary function of teeth is grasped and holds the food in the mouth cavity, they also modified to serve as a grinding mill for chewing food that mentions to mechanical digestion. With the help of the teeth, tongue, and jaw movement, food are chewed and mixed with saliva that secreted in the mouth and allowing chemical digestion to happen. The digestion of a ham, cheese, and lettuce sandwich begins in the mouth. The food in the mouth active the endocrine glands to secretion digestive enzyme that called salivary amylase. It helps to break down carbohydrates and starch. Thus, at this stage, the bread of ham and cheese sandwich chemically digested. Amylase is a starch digesting enzyme which breakdowns bread (starch) into maltose that

Mouth:-It contains the teeth, gums, soft palate, hard palate, the tongue and the lip. The soft and hard palate`s functions of prevent the large pieces to enter the body and mainly separate from trachea and esophagus. The tongue is where the saliva is mixed with enzymes and watery content to moist the food and allow the movement during mastication. The teeth breaks down food.

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

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.

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 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 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

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

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.
