sandwich you had just ate. But it is still sitting in your stomach!! Now how does this work, how did your body absorb all that food? It all goes back to the digestive system. http://kidshealth.org/kid/cancer_center/HTBW/digestive_system.html ( I didnt copy direct quotes, however I had used the idea of the beginning in my research on the digestive system to help the reader better understand the system) The whole purpose of your digestion system is to break down and absorb the energy and nutrients
Digestive Process Digestive Process It is in the mouth, that the Thanksgiving feast begins its journey through the fabulous digestive system. It is here that the lips, cheeks and tongue, carefully position the food that the teeth will chew. This chewing process breaks up the food, this being a part of mechanical digestion. While the teeth grind up the turkey and tasty stuffings, the salivary glands begin emitting enzymes, these enzymes being contained in saliva. This saliva helps to dissolve
species’ digestive systems. The digestive system of an organism is the system that makes food absorbable into the body. The food that the organism takes into their body is broken down through an organ to make it easier for the body to take the nutrients it needs from the food. The food that is broken down in the digestive system is then turned into energy for the organism. The earthworm digestive system is one of the simplest digestive systems compared to the frog or a human. The digestive system is
The Digestive System This is a combination of different set of organs which changes whatever we eat or drink in things that the body uses for growth, energy and repair. The body usually absorbs the nutrients, after the food has been broken down by different chemical processes, the rest is normally expelled as waste product. This whole process can usually take up to several hours or less. The digestive system is also known as the alimentary canal or the gastrointestinal tract. (Tucker L. 2005).
Digestion is defined as the process of transforming foods into unites for absorption. The Digestive System is a complex network of organisms that have six major processes: The digestion of food, the secretion of fluids and digestive enzymes, the mixing and movement of food and waste throughout the body, the digestion of food into smaller pieces, the absorption of nutrients, and the excretion of wastes (Inner Body (1).) Mouth- Digestion begins in the mouth. Physical actions, such as chewing, breaks

The overall purpose of the digestive system The digestive system has of a chain of linked organs that work with each other to digest, and break down food into molecules that are put in the circulatory system. Then takes them to the body’s tissues. The most important structures in the digestive system are the tongue, mouth, intestines, esophagus, stomach, and anus. The liver, gallbladder, and pancreas are with the digestive system also. How does the digestive system function Food comes in the mouth
What happens to food once it is ingested? Where does it go? How is it broken down into smaller pieces? The digestive process is very complex, but simple to understand. It involves several steps that include from being chewed inside the mouth, to landing in the stomach for more breakdown, traveling through the intestines, and finally exiting the body. It starts with a process called mechanical digestion. It is when food is chewed in the mouth and turned into small pieces, then is swallowed. The tongue
The Digestive System The digestive system is a group of organs that perform the process by which food, containing nutrients, is eaten and broken down into different components. This breakdown makes it possible for the digested material to pass through the intestinal wall into the blood stream. The digestive process contains many different steps that take place in many different organs.The first step of digestion begins at the mouth, where the food enters the mouth. Saliva is secreted from the
dog and the lizards’ digestive and reproductive systems are explored within this essay. 2.0 The dog’s digestive system The dogs’ digestive system mainly consists of 15 different parts. These are the oral cavity, oesophagus, diaphragm, stomach, liver, gall bladder, pancreas, duodenum, jejunum and ileum, transverse colon, ascending colon, descending colon, caecum, anal canal and the rectum (Aspinall and Cappello, 2009). Each of these play an important role in the dogs’ digestive system. Starting
The digestive system of the horse is a long and complex system that ensures that a horse gets enough nutrients to different parts of his body. It is also a very delicate system because of its size and complex nature. With all the different twists and turns that are involved in the process of digestion it is easy for this process to go wrong, which could cause a horse to experience extreme discomfort or even the loss of its life. The process of digestion begins with the grass. To survive a horse
The digestive system is a group of organs that perform the process of digestion, which is food, containing nutrients, is eaten and broken down into different components. This whole system is designed uniquely to perform to turn food into energy you need to survive. The digestive system starts with the mouth and ends with the anus. The mouth being the very beginning of the digestive tract is literally when the first bite of food is taken. Chewing up food breaks the food into little pieces, while
The digestive system, in organisms like the mink and human, is supposed to break down the food being eaten to transfer into energy. This energy helps other functions of the body that would in turn keep it alive. The digestive system includes organs such as the stomach, intestines, liver, etc. Digestion starts at the mouth, though. With the observation of the digestive organs of the mink, an individual can see that the entire liver is the darkest looking color of the organs in the gastrointestinal
going be digestive. The system I bring to you is the digestive system, this system has two group of organs which are the gastrointestinal tract and accessory digestive organs. The digestive system is a group of organs working together to convert food into energy and basic nutrients to feed the entire body. Food passes through a long tube inside the body known as the alimentary canal or the gastrointestinal tract (GI tract). The alimentary There are six major functions take place in the digestive system
Digestive System The digestive system is an amazing system that is capable of working a large number of different functions. The digestive system is the process of transforming food into a source of energy, cell repair, and nutrition for the human body like vitamins, minerals, fats, proteins and, carbohydrate. The system is made up of organs that include the mouth, liver, gallbladder, stomach, anus and rectum, large intestine, small intestine, pancreas and esophagus. The digestive system covers
The organs of the digestive system are in two different groups. One is the alimentary canal known by as the gastrointestinal tract. It is a muscular tube that digests the food and breaks it down and absorbs the digested fragments in the lining of the blood. The organs in the gastrointestinal tract are the mouth which the food comes into the body and out of the body by peristalsis. The pharynx called the throat which receives the food; this is where swallowing occurs, while the esophagus transports
and the movements of the smooth muscles help your food make its way into the esophagus. The digestive tube is mainly lined with four layers. There are smooth muscles called sphincters that are between the junctions of the GI tract. These sphincters are what help the food pass through the digestive system and then they relax in order to deposit the food into the stomach. The main function of the digestive system is to break down food
The human digestion system is very complex. It starts with the mouth, salivary glands, pharynx, esophagus, stomach, liver, pancreas, gallbladder, small intestine, large intestine, then ends/exits with the anus. Each step is essential to the whole system. For example, the mouth chews food and mixes it with saliva produced by the salivary glands, and then the pharynx swallows chewed food mixed with saliva, this is followed by the food traveling through the esophagus to the stomach where the food gets
The Pancreas is a very soft and tadpole shaped gland. Most of the pancreas is located deep to the greater curvature of the stomach. The pancreas is important to the digestive system because it produces enzymes that break down all categories of food. The Pancreas also creates a juice called pancreatic juice which drains from the pancreas into the duodenum. About 1200 to 1500 ml of clear pancreatic juice is produced daily and mostly water is consisted from it containing enzymes and electrolytes
Capillaries are very small; in fact, capillaries are the tiniest of all blood vessels. They form the connection between veins and arterioles in the circulatory system. However, capillaries tend to be found everywhere. Unlike veins and arteries, the capillaries main function is not transporting blood. They allow the movement of substances, mainly gases Oxygen and Carbon Dioxide into and out of the capillary. Capillaries have very thin walls that are only one cell thick, which allows substances (such
