What Are The Three Functions Of The Digestive System

The digestive system absorbs the minerals and nutrients from the foods that have been eaten. The break down of food beings in the mouth, where the

Digestion starts in mouth and it is going through several steps. Teeth which are a Mechanical digestion start tearing and crushing the food down into small pieces so that the food will smoothly run down our throat. The salivary glands are located underneath the back of our tongues and that’s what is creating our saliva. The saliva is the Chemical Digestion is helping soften the food in the mouth so it is easy to swallow. Also saliva is the first out of several chemicals that is breaking the food into smaller bits. The tongue is the muscle that works with the food and saliva to form something similar to balls that can be swallowed. Also tongue contains taste buds so that we know if the food is salt, sweet, sour or bitter. Esophangus is a simple transportation tube that is joining the throat with stomach. When swallowing we are closing a trap door in our throats called the epiglottis. By closing this trap we are preventing the food prom going to trachea and into our lungs. Also Food moves down the esophangus using muscles not gravity. Stomach is the first stop after the Esophangus. When the food gets into stomach the stomach uses chemicals to try to make the food smaller. These chemicals are called gastric juices and they include hydrochloric acid and enzymes. (Enzymes are

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 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 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.

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,

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

The mouth is where the digestion first begins as firstly the scent of the food will travel to the nose causing the salivary glands in the mouth to produce saliva as there are three pairs that do this. As you are chewing the food with your teeth the food starts to get broken down more saliva is produced along with the breaking down. The secretion will be transferred into the mouth and the tongue as the salivary glands are causing it to do this. Also, the digestive juice contains an enzyme which is known as salivary amylase which now begins the digestion of carbohydrates as well as lubricating the mouth in order to help with the bolus formation.

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 digestive systems starts as food begins to enter the oral cavity through the mouth. As digestion continues the tongue plays an important role by pushing broken down food from the secretions during the chemical reaction of salivary glands releasing amylase from mouth to the oropharynx. The oropharynx reactions with epiglottis, which a flap that closes during digestion to make sure food does not enter windpipe. The glottis is the opening that goes to lungs, if food enters the oropharynx it would make the epiglottis fold back whenever the glottis is closed food is allowed to go into the esophagus. There are two sphincters of the esophagus, the upper and lower esophageal sphincters. The upper esophagus is concluded of a buddle of muscles who

he digestive system is a physiological marvel, composed of finely orchestrated chemical and physical activities. The food we ingest must be broken down to its molecular form for us to get the nutrients we need, and digestion involves a complex sequence of mechanical and chemical processes designed to achieve this goal as efficiently as possible. As food passes through the gastrointestinal tract, it is progressively broken down by the mechanical action of smooth muscle and the chemical action of enzymes until most nutrients have been extracted and absorbed into the blood.

How the process of human digestion works is it starts with your mouth, the digestion starts as soon you take your first bite of your meal. When you chew it helps the process by making it easier for the food to digest. Also the saliva mixes with the food so that it can form it into something that the body can absorb and use. The next place the food goes is the pharynx (throat), then the esophagus or swallowing tube. The esophagus gets the food from the throat to the stomach. After the stomach is the small intestine it continues the breaking down process of the food by using enzymes released by the pancreas and bile from the liver. There are 3 other organs that help the small intestine break down the food we eat. They are pancreas, liver, and

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.”
