I. Introduction
The human digestive system consists of organs from the gastrointestinal tract, which is a tube that goes from the mouth to the anus. Either end of the mouth and the anus contain a lumen, which is open on each side for the external environment. Everything inside the lumen is considered to be external to the body. The organs that make up the GI tract consist of the mouth, stomach, pharynx, esophagus, large intestine, small intestine, and the anus. The human digestive system also consists of other organs that help with digestion, such as the salivary glands, teeth, liver, tongue, gallbladder, and the pancreas(Allen, Harper 2009).. The digestive system aids in ingesting food, secreting juices, moving and mixing food, breaking down food into absorbable, tiny molecules, absorbing digestive substances and molecules throughout the GI tract wall and inside the body, discharging through the anus (Tortora 2012).
There are two kinds of digestions, mechanical, and chemical digestions. Mechanical digestion is the breaking down of food into smaller pieces. It starts off in the mouth, and goes through the stomach and the small intestine. In the mouth, masticating or chewing occurs, which mechanically breaks down the food and allows it to be swallowed and travelled to the stomach. As the food reaches the stomach, the mixing of food and digestive juices occurs in until the food reaches the small intestine (Allen, Harper 2009). The mixing of food and the digestive juices makes it easier for digestion to occur. Chemical digestion is the breakdown of large molecules by the use of enzymes to break down the bond between carbohydrates lipids, and proteins. Enzymes are large protein molecules and are used to break down ...

One of the few differences in mink and human digestive organs is that the large intestine is much smaller in the mink and doesn’t coil around the abdominal cavity like the large intestine in a human organism. Furthermore, the size of the stomach in minks is required in order for them to eat much larger prey and be able to store more energy. The pyloric sphincter, which is useful in preventing the bringing back the food from the small intestine back into the stomach, plays a more significant role in the digestive process of the mink compared to a human. The mink and human are similarly related on an evolutionary chain.
4)Stomach: The stomach squeezes and mixes food with enzymes for hours before it releases the mixture into the small intestine.
In order for this breakdown to happen, the ‘tube’ through which the food travels requires assistance from a number of other digestive organs starting with the salivary glands, and later receiving
It measures about 1.5m in length, and 6.5cm in diameter, wrap around the small intestine, in a shape of an arch. It is made up of caecum, colon, rectum, appendix, anal canal and anus. About 90% of water is re-absorbed here, which is one of its major function. There are also bacteria in the large intestine that converts protein to amino acid. These bacteria produce gas, acid and vitamin B &K by breaking down amino acid. These vitamins are absorbed here. The content of the large intestine changes to a semi solid state called faeces due to water re-absorption. (Tortora G. and Derrickson B.

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).)
The whole purpose of your digestion system is to break down and absorb the energy and nutrients it needs from the food you eat. The sandwich, strawberries, and orange juice you have just consumed is going through this process right now! The process of digestion begins with ingestion, this is when you take a bite of what you have planned to eat. When you took a bite of your sandwich and strawberry slices you were essentially beginning the process of digestion. Second comes the job of your digestion, which is a much more time-consuming and complex process for your digestive system. It begins once you have began chewing your food. There are two known types of digestion, these include Mechanical digestion, which is when you “physically break down the food into smaller pieces”, for instance chewing a burger and having it result in several chunks, and Chemical Digestion which is when you chemically break down your food, such as eating a slice of br...
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
Digestion have a function of breaking down all food into our body. Our body use all nutrients to help in the process been health and growth. Digestion supplied small molecules that will be absorbed into our bloodstream.
Hi there. My name is Albert and this is my adventurous story of my journey through a human. I was a delicious gourmet hamburger with fresh ingredients like salad, mustard and an angus beef pattie. I was dumped into a family feed box labelled with a massive golden arched ‘M’. Now, I’m quite an intelligent burger, unlike my other food companions and I love studying about the fascinating human digestive system when I went to Burgerton College. I’m here to tell you first-hand about my digestive journey into the human body! Here is a map of the human digestive system for your convenience to pinpoint where I am in my journey as I am recounting my story.
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.
