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

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 seats hold the crowd in place during the game. 8. Lysosomes - Lysosomes help the digestive process. They contain enzymes that speed up the process and help digestion of food and other materials. Lysosomes are like mitts in baseball.
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 proper functioning of one system relies on the proper functioning of the other system. In other words, the digestive system needs to be in good working order to support the functions of the cardiovascular system. An example of the digestive and cardiovascular systems interrelating is: the first step in digestion of fat is to dissolve it into the intestine where bile acids produced by the liver dissolve the fat into fatty acids and cholesterol. The bile acids join with the fatty acids and cholesterol and vessels then carry the changed fat to the veins of the chest, and the blood carries the fat to storage in different parts of the body.
This organs help get rid of the wastes from the body as either urine or

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 irony I usually witness is that those against it, square measure the everyday obsessional bodybuilders that may claim "your killing your gains" not consumption, solely to induce up within the morning Associate in Nursingd do an hours fasted cardio to "target fat".

I am not for Intermitent abstinence, or against it, square measure there times that you simply may use it?âEUR¦YESâEUR¦are there times it mustn 't be usedâEUR¦by this I mean, square measure there times that it not best to use itâEUR¦YES.
Next, this semi-liquid mixture enters into the small intestine, where most of the calories and essential nutrients are absorbed by your body. Finally, whatever is left passes into the large intestine and eventually through the colon as it is expelled from the body. Gastric bypass surgery restructures the stomach and intestinal system, resulting in intentional malabsorption and limiting the patient 's ability to eat large quantities of food.
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
By slowly proceeding through all these steps one by one, foods are eventually been broken down into small and simple particles of nutrients which absorbed by human body and the waste (which cannot be absorbed) to be eliminated (refer to Figure 1 in Appendix 1). Firstly, the human digestive process begins with ingestion. Ingestion involves the intake of food into the mouth where the food is chewed into smaller pieces and mixed with saliva. Saliva is a liquid that contains enzymes such as lysozyme (which kills bacteria) and salivary amylase (beginner of digestion in starch).
The small intestine begins with the duodenum which has the large responsibility of continuing to break down the food. The jejunum and ileum are
Our gastrointestinal tracts work hard to keep us healthy and happy. When gut health is compromised, we can face major health consequences. Here’s how to use good nutrition to keep your digestion humming along. “Heal the gut and you heal yourself.” – Gerard E. Mullin, MD
Now the digestive system is what helps us get some of the energy we need but the muscular system is what moves the food around our digestive track an out of our bodies. One of the biggest diseases that the muscular system has to deal with is the Iron Maid diseases. This malfunction is where the makeup of your muscles is remade and when they are impacted in a forceful way they turn to bone. This make the patient unable to move and it very slowly creates a pressure on their chest and stomach and makes them unable to do anything ever again.
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 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.
