This is one of the most amazing system, this system can be can break down food. It extends from the mouth to the anus and closely associated with cardiovascular system. You never begin to think how this system work when you go to put your favorite food in your mouth, you don’t begin to think about how it’s 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. Am start with the begin of the digestive system the begin of the digestive system is the mouth, as soon you take that very first bit of that delicious slice of cold watermelon, the digestive system start to work. When you start to chew you use your teeth to break down the food up in pieces which you eventually going to swallow, which lead to the food been process in the throat which also call pharynx. From the throat the food goes from to the esophagus also call the food tube. The esophagus is a muscular tube connecting the pharynx to the stomach that is part of the upper gastrointestinal tract. It carries swallowed masses of chewed food along its length (Tim The small intestine is made up of the duodenum, jejunum, and ileum. In the small intestine food that has already been broken down by chewing and stomach enzymes is further degraded by additional enzymes. Some of these chemicals are secreted in the lumen (Health Line, December 9, 2014). Small intestine it absorb most of the nutrients from we eat, then there is the long intestine. The large intestine (colon) extends from the cecum to the anus and includes the ascending colon, the transverse colon, the descending colon, the sigmoid colon, and the rectum. (Healthwise Staff,2014). The large intestine is the last section of the gastrointestinal tract that performs and absorbing water and vitamins while converting digested food into feces. Even though it’s shorter than the small intestine in length, the large intestine is thicker then the small intestine. The last and finally part is the anus, the opening at the end of the alimentary canal through which solid waste matter leaves the body. Anus is where all the food that goes in your mouth it comes back out of the anus, the anus is connect to the bottom of the rectum. In the digestive system there are includes accessory organs that assist in digestive processes which include salivary glands, liver, gallbladder, and pancreas. The salivary gland is found around your mouth and throat, next is the liver. The liver is the largest intestine in the body it stores energy, removes poisons and digest food. Then comes the
The last parts of the large intestine are the Rectum and the Anus, the rectum is responsible for the excretion of faecal matter from the body while the anus is the actually ring of muscle at the end of the rectum which allows for the passage of waste material to exit the body.
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.
The small intestine empties into the cecum. The cecum along with the large colon make up the large intestine. Digestion in the large intestine occurs by bacteria and protozoa. arg.gov.sk.ca - arg.gov.sk.ca - arg.gov.sk.ca - arg.gov.sk.ca - arg.gov The energy content found in feeds and how it is measured in Kilocalories (kcal).
During an average lifespan, as much as 45 tons of food can pass through one’s digestive system. Food travels almost 9m through a long tube inside the body known as the alimentary canal or the gastrointestinal tract .
The digestive system otherwise known as the gastrointestinal tract (GI tract) is a long tube which runs from the mouth to the anus. It operates to break down the food we eat from large macromolecules such as starch, proteins and fats, which can’t be easily absorbed, into readily absorbable molecules such as glucose, fatty acids and amino acids. Once broken down, these molecules can cross the cells lining the small intestine, enter into the circulatory system and be transported around the body finally being used for energy, growth and repair.
Large Intestine- The large intestine is made of 3 parts; the cecum, the colon, and the rectum. Some refer to the large intestine as the colon, because the colon contains four separate parts; the ascending colon, the transverse colon, the descending colon, and the sigmoid colon (WebMD (2).) The cecum connects the small and the large intestine, acting as a transition area for food to travel. The ascending colon takes feces from the cecum to the transverse colon, during this process, bacteria digest fecal matter for the release of vitamins. The longest part of the colon, the transverse colon, is where the most absorption within the large intestine takes place. The descending colon transports feces from the transverse colon to the sigmoid colon. The descending colon walls also absorb water, nutrients, and vitamins from the feces, and can store the feces until it is read to be eliminated. The sigmoid colon can also

Imagine you are eating a sandwich containing wheat bread, ham, lettuce, and Swiss cheese. Do you ever wonder where the nutrients go from all of the previous listed ingredients? Well, when a bite of this sandwich is taken, the mouth produces a saliva enzyme called amylase. This enzyme immediately goes to work by breaking down the carbohydrates that are in the bread. Once, the bite is completely chewed, the contents then are swallowed and go down the esophagus and begin to head towards the upper esophageal sphincter and the is involuntarily pushed towards the stomach. The next passage for the sandwich is to go through the lower esophageal sphincter; which transports the sandwich into the stomach.
As the digestive system breaks down your food, after it's broken down it turns into energy. Your circulatory system takes some the produced energy and transports it around the body, delivering it and other blood, nutrients, oxygen, and more compounds to every cell in your body. The digestive depends on the circulatory as much as it does vice versa because they need the blood, nutrients, and energy (broken down food) that was produced from both systems. Many digestive organs need to use about 30% of cardiac output. Both the digestive and circulatory systems get rid of unwanted or unneeded materials (waste) and feces (poop). The vial substances are absorbed by the small intestine, where it is put into the bloodstream, so it can be circulated around the body. The most important thing is that with no nutrients and circulation, there's no life.
During digestion, the body breaks down food into smaller molecules that could then be used by the body’s cells and tissues in order to perform functions. This starts off in the mouth with the physical movements of chewing and the chemical breakdown by saliva. Enzymes in the stomach break food down further after traveling from the mouth through the esophagus. The food from here then moves into the small intestine, where pancreatic juices and enzymes dissolve proteins, carbohydrates, and fibers, and bile from the liver breaks down fats into these small molecules. Any portion of the fibers or food that were unable to be broken down are passed from the small intestine to the large intestine, which is where the digestive tract transitions into the excretory tract, then the colon and out of the rectum. Any liquids that have been stripped of their nutrients by the body proceed from the stomach to the kidneys. In the kidneys, sodium ions (Na+), uric acid, and urea are exchanged with water, which moves urinary bladder and is excreted through the
Absorption is the way of digesting the food molecules into the small intestine. This process of absorption pass throughout the wall of the small intestine into the bloodstream. The bloodstream carried out all important nutrients to the
A digestive system is where the food is passed through the animal’s body, as is broken down and used for different and specific reason to the animal. There are 3 main digestive systems; these are Monogastric (carnivore), Hindgut Fermenter and a Ruminant. Each of these digestive systems digests foods using nearly the same organs, but for different functions.
...he Buttermilk White bread. The food makes its way to the transverse colon and extra nutrients are released form the cellulose of the undigested particles. It continues on to the descending colon. There I start to manufacture vitamin K and other B-complex vitamins. Those are then absorbed into my large intestine.
The excretory system, which includes the rectum and anus helps the digestive system by getting rid of waste and the digestive system helps the excretory system by breaking down food to be eliminated from the body. Wow! The human body wouldn’t be able to work without one or the other. Anyways, I hope you enjoyed reading my journey throughout the human digestive system. I hope to write again from where my next journey from here will begin- perhaps it will be in the ocean or along Sydney Water pipes. Until next
The digestive system is a very important system in the human body. It is a group of organs that work together to turn food into energy and nutrients in the entire body. The food that was chewed in a humans’ mouth now passes through a long tube that is inside of the body that is known as the alimentary canal. The alimentary canal is made of the oral cavity, pharynx, esophagus, stomach, small intestines, and large intestines. Those few things are not the only important accessories of the digestive system there is also the teeth, tongue, salivary glands, liver, gallbladder, and pancreas.
