The digestive system is a major component of our body, without it we wouldn't be able to receive the essential nutrients to live our daily lives. The digestive system consists of a number of organs, required for it to work correctly.

Mouth

The beginning of the digestive system starts at the mouth. The process of digestion actually occurs before you consume food. When you see, smell, taste or think about food your body prepares for the food it expects to arrive. This starts in your mouth where your senses trigger the glands that produce saliva (salivary glands), producing amylase, which helps your body digest carbohydrates. Once you put food in your mouth you add saliva to the food by chewing. Chewing uses the action of your teeth to break …show more content…

It is actually 6.4 metres long! The job of the small intestine is to absorb nutrients, water and electrolytes. The small intestine consists of three main parts which all play a part in performing these tasks. The Duodenum is the first part. The duodenum is the shortest part of the small intestine. It's job is to receive the half digested food and neutralise it. The next part of the small intestine is the Jejunum. The Jejunum is the middle part of the small intestine and it is here that the digestion process is completed. The last part is the Ileum. Its function is to absorb Vitamin B12 and absorbs any nutrients that weren't yet absorbed by the Jejunum.

Large Intestine

After passing through the small intestine the food now reaches the large intestine. The large intestine is divided into three parts: the ascending colon, the transverse colon and the descending colon. These sections together complete the process of digestion. The large intestine is a tube structure which is about five feet long. The function of the large intestine is to absorb vitamins (B Vitamins and Vitamin K) into your body, as well as producing stools which are stored in the descending colon (rectum).

Extra Organs

As well as the five main organs mentioned there are also three more organs that are essential in the digestive system, but aren't apart of the main digestive tract. The accessory organs of the digestive system are the liver, the pancreas and

The liver has a portal vein as well as a hepatic vein. It also has unique exchange blood vessels similar to capillaries, called “sinusoids.” How do these unique structures determine the function of the organ? • The livers main function is to filter and process the blood it receives. The portal vein and hepatic vein then deliver the nutrient rich blood to the capillaries (sinusoids).

The digestive system is responsible for chemically and mechanically breaking down food and includes organs such as, mouth, esophagus, stomach, small intestine, rectum, anus, and additional accessory organs. These organs all aid in the breakdown of food. Food is broken down mechanically by chewing and churning in the stomach, and chemically by acidic enzymes in the stomach and in the small intestine which receives enzymes from the pancreas that are specifically designed for the breakdown of nutrients. Once the food and nutrients are broken down, the excretory system removes whatever the body decides is waste by filtering blood in the nephrons of the kidneys and turning it into urine which is then collected in the bladder and removed from the body when the bladder is

Mary Roach dives into the world of science and biology throughout the novel, Gulp, and explains it particularly in reference to the alimentary canal. She starts at the beginning with simply how eating works when it comes to taste preferences. Since humans tend to “taste” through their noses, the act of eating is actually more of an olfactory experience, surprisingly enough. Next, the food must travel past the saliva which carries digestive enzymes and kills proteins in order for the food to get to the stomach. The gastric acid within the stomach then breaks down the food and sends it to be filtered back out through the anus.

The bolus then goes to the pharynx where swallowing occurs. During deglutition in the pharynx there is a “flexible flap of elastic cartilage that’s function is to keep food out of the lower respiratory passages” called the epiglottis (Human). The bolus then goes to through the esophagus where segmentation(circular muscle contractions of esophagus that allows the bolus to mix) and peristalsis(longitudinal muscle contractions of the esophagus that allows the bolus to be push down bolus to the stomach) happens. Then it goes through “ringlike muscles that contract/close a bodily passage or opening” called sphincters (Sphincter). The bolus goes through one called the gastroesophageal between the end of the esophagus and the beginning of the stomach in order to enter the stomach.

Introduction Gallbladder is an organ in the body and it is part of the biliary system. It is a pear-shaped muscular sac that is located on the ventral surface of the liver and on the right side of the abdomen. Moreover, it has 3 layers; an outer serous peritoneal layer, a middle smooth muscle layer and the last layer is an inner mucosal layer which is connected to the lining of the bile duct. The main function of the gallbladder is to store and concentrate bile which helps the body to break down and digest fats.

The Digestive System The digestive system is a system consisting of the mouth, oesophagus, stomach, gallbladder, small intestine, large intestine, the rectum and the anus. The functions of the digestive system are: • To break down food particles into molecules for digestion • To absorb into the bloodstream the small molecules produced by digestion • To eliminate un digested and unabsorbed foodstuffs and other waste products from the body The full digestive process begins at the mouth. The food enters the mouth and is chewed.

The main components involved in this system in heart, blood, and blood vessels. Blood is a oxygen and nutrients filled fluid that has plasma, red blood cells, white blood cells, and platelets and removes all waste materials from body tissues. Without the brain the circulatory system does not work, heart function and fluid circulation does not work unless they are triggered by the brain. The digestive system is a group of organs working together to convert food into energy and basic nutrients to help the entire body. This system consists of the salivary glands, pharynx, mouth, esophagus, liver, gallbladder, stomach, pancreas, small and large intestine, and the anus.

The muscular system is very important for everyday life. Without it we wouldn't be able to carry out everyday tasks such as writing this paper or tying our shoes or anything. This system also helps us distribute wastes when our body doesn’t need them anymore, which is important because if the wastes build up the toxins will enter your system the wrong way and it will harm you eventuly. This system interacts with the many other systems but the main two are the nervous system and the digestive system. The nervous system is what controls the brain and the brain tells us to move certain parts of our bodies without us knowing it, this is how our involuntary muscles move.

The digestive system is located around the stomach area. Along with the digestive system, many other organ systems all work together to create an organism. An example of this would be if a person eats a sandwich and then goes for a run. During the run, the circulatory system helps the body breathe, the muscle system helps the bones move, and all the while the digestive system digests the food. Later on, the excretory system gets rid of the waste, or food that the body can’t use for nourishment.
