The digestive system is a series of connected organs whose purpose is to breakdown the food we consume. Food is made up of large, complex molecules, which the digestive system breaks down into smaller, simple molecules that can be absorbed into the bloodstream. The simple molecules travel through the bloodstream to all of the body's cells, which use them for growth, repair, and energy.
The digestive system involves two stages: mechanical breakdown and chemical breakdown. In the mechanical breakdown, teeth physically break large pieces of food into smaller pieces. In the chemical breakdown, digestive chemicals known as enzymes break apart molecules of food.
Carnivore; Dog
A carnivores’ digestive system is quite simple, being a long piece of pipe with a single bulge near the beginning. All carnivores’ digestive systems are really quite similar and all function in the exact same way.
Diet
The dog, like all carnivores, has a diet of meat. Meat contains protein, which is used for growth and development and to form part of important substances in the body such as enzymes and antibodies. Meat also contains fat, which is used as energy.
Structures
Mouth- digestion begins in the mouth. The dog’s jaw contains incisors, canines and ridged molar teeth. Incisors are used for biting the food; canines are used for tearing the meat and the molars are used for tearing or crushing the meat. Salivary glands are used to lubricate the meat but are not important in digestion.
Stomach- its small size gives a good estimation of the amount of food the dog can consume at any one time. The stomach has two functions. Firstly, it is used for storage, although relatively small, this is all that is needed, as the food of a carnivore, is nutrient dense, allowing one small meal to sufficient for many hours. Secondly, the stomach function is to subject the food to a concentrated solution of hydrochloric acid, which dissolves and liquefies it.
Small intestine- is very vital in digestion. The small intestine in a dog is approximately 20 feet in length. The dissolved food leaves the stomach in a series of spurts, controlled by a valve and enters the small intestine. It is in the small intestine that food is digested and enters
Digestion begins when food is eaten by your dog. Once swallowed, it begins its journey down the oesophagus into the stomach. This is where it will be broken down by hydrochloric acid into a liquid. The liquid will then pass into the small intestine. This is where the main part of the digestion takes place. Assisted by the liver and pancreas the nutrients
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
It has organs that have different roles to help the digestive system do its job. One of the organs, names is the esophagus. It is a muscular tube around the throat area, it is connected to the stomach, its job is to carry food down it.The stomach is located on the left side of the abdominal cavity. Its job is to break down the food it uses acid to help it when doing its job. Next to the stomach is the small intestine. The small intestine is a long, thin tube that is located in just inferior in the stomach and takes up most of the space in the abdominal cavity. Its job is to absorb nutrients and materials next is the gall bladder it is located under the liver and its job is to store and recycle excess bile from the small intestine so that it can be reused for the digestion of subsequent meals. After the gallbladder is the large intestine. It is a long thick tube that is located under the stomach and wraps around the borders of the small intestine it job is to absorbed water. Finally, there is the pancreas it a large gland located just inferior and posterior to the stomach. And its job is to further break down food after it has left the
The mouth is the very beginning of the digestive tract, and is literally where the first bite of food is taken. Chewing food breaks down the food into little pieces, while saliva mixes with the food to assist with the process of breaking it down. After the food has been broken down, it enters the esophagus, which is in essence,
The next part of the digestive system is the __small intestine__, which is a long, windy and thin tube that snakes its way around the lower part of your belly. Here the food is mixed with bile and other enzymes, which are created by the liver and pancreas, to break down the molecules in the food even further. Once the food has been turned into glucose, those molecules are absorbed by the wall of the small intestine and move into the blood, where they provide energy for the body. The small intestine also absorbs vitamins, minerals, simple fatty acids and amino acids. This is another slow, gradual process and takes 3-6
The small intestine then takes in the partially digested food and mixes it and absorbs the nutrients. Next, is the large intestine which has the job of absorbing water and adding mucus to the food. The anus is the end of the digestive tract and is where all the waste exists. The liver then produces bile which acts on the fat, the gallbladder stores the bile until it is needed. The pancreas produces insulin and digestive
The digestive system starts with the mouth and goes all the way down to the rectum. Along the way, your digestive system breaks down the food you eat so you can absorb the nutrients and use them for energy.
Dogs are carnivores.Their digestive system, from the mouth through their intestines, is designed to cope with a meat diet. The dog's teeth are adapted to tear food into swallow able sized chunks rather than to grind the food, and there stomachs can digest food in this state.
The function of the digestive system is to break down food into smaller pieces, remove solid waste, and to absorb nutrients in the blood. This is done by teeth breaking down the food into smaller pieces, the food travelling down the esophagus, peristalsis moving the food from esophagus to the stomach, strong muscles in the stomach crush food, food then travels to the small and large intestines, turned into solid waste, and finally removed out of the rectum. One of the diseases found in the digestive system is cholera, which is an acute infection of the small
There is a significant difference between humans and dogs in their need for carbohydrates and in their ability to digest them. The digestive tract of a human is longer than that of a dog, and the formation of jaws and teeth is entirely different. A dog's digestion starts in the stomach. Dogs' teeth - all 42 of them - are built to tear flesh apart. Dogs gulp their food as fast as they can, which then reaches the stomach with no digestion having taken place.
The digestive tract starts in the mouth and then goes to the pharynx. Then goes to the esophagus. Then from the esophagus then to the stomach. From the stomach it goes to the small intestines. Where the food is broke down using the enzymes of the pancreas and bile from the liver. Then thru the colon and the rectum and then out the
The Digestive System is like tubes that convert food into body fuel. These tube-like organs are about thirty feet long. It begins at your mouth and ends in the anus. Once food enters your mouth the Digestive system has already began. It first is broken down by saliva and passed down your esophagus and into your stomach. There, it’s broken down into proteins, carbohydrates, fats, vitamins and minerals. After it is broken down, the Small Intestine is in charge of passing nutrients into the blood stream and into the liver. Anything that is left (waste) passes into the large intestine. The waste is eaten by harmless bacteria and dead cells, which forms feces and is let out every time you use the
The digestive system begins with the mouth and extends through the esophagus, stomach, small intestine, and large intestine, ending with the rectum and anus. It’s a made up gastrointestinal that tracts the liver, pancreas, and gallbladder. The digestive system helps the body to digest food in it.
The digestive process is the process by which foods are broken down, absorbed or excreted by the body. Digestion start from the mouth. Mastication is the broken down of food into smaller particles and saliva contain mostly water which aid in chewing and swallowing. It also contain important enzyme amylase, that begin the broken down of starches or carbohydrate. The food passes the esophagus from the mouth, a long tube which connect from the mouth to the stomach. The muscle on the upper part of the stomach relaxes to receive large volumes of swallowed food or liquid from the esophagus. Stomach is a muscle that helps to break down food into smaller pieces. Small intestine comes next in the order of digestive system. The small intestine is an
The digestive system is initiated when a person smells food, which triggers salivary glands start to secrete saliva in one’s mouth. While the person begins chewing thus breaking down the food into smaller pieces, their saliva increases. As more saliva is produced, it begins the process of breaking down food into different forms of the individual’s body thereby absorbing it for usage. . In the digestive system, liquids are produced to help break the food down further. By chewing the food more, a person is helping to improve their digestion.
