The Digestive System Of A Human

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

Digestion is a process in which insoluble food is broken down into particles which are made into soluble particles enough to be absorbed and to be used by the body and into the bloodstream. These soluble particles are major macronutrients made up of protein, carbohydrates and fats which are needed for essential maintenance for the functioning of the human body. Nutrients are found in foods- proteins are found in red meat/poultry; sources of carbohydrates include

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.

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.

Salivary glands are responsible for excreting saliva which helps with chewing and swallowing. The saliva is the first step to digestion; enzymes in the saliva begin the process.

The digestive system are organs converting food into energy and basic nutrients to feed the entire body.

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

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

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 the body’s system of organs that provides our body absorbable nutrients and excretes waste. Our digestive system is used to process these nutrients and turn it into energy. The parts of the digestive system include the salivary glands, mouth, esophagus, stomach, liver, gallbladder, pancreas, small intestine, colon, and rectum.

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

It also lubricates food to facilitate swallowing and dissolves some food molecules. If the salivary glands were damaged or dysfunctional, the process of breaking down starches into sugar would not begin in the mouth, the food would not be lubricated, some food molecules would not be dissolved, and there would be a higher change of infection as saliva contains a bacteria-killing enzyme and antibodies that guard against infection.

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 through the empty organs of the GI tract. The liver, pancreas, and gallbladder are the strong organs of the stomach related framework. The stomach related framework enables the body to process nourishment.

You use your mouth to chew your food, causing it to break down in pieces hence using the process of mechanical digestion, and you also use your mouth to form an enzyme known as amylase, or saliva which breaks down your food chemically, for instance when your saliva touches the bread from your sandwich it begins to form into sugars. Incase you did not know “enzymes are chemicals that are used to break down foods into other chemicals”. Saliva can also help you swallow the food by lubricating and “breaking down the complex carbohydrates into simple carbohydrates.”
