Digestive System
The digestive system is a very large system in our bodies. This system runs all the way from the mouth, where we put whole food in, to the large intestine that includes the rectum and anus, where waste exits. The digestive system is composed of the mouth, esophagus, liver, stomach, gallbladder, pancreas, small intestine, large intestine, rectum, and anus (Diseases). The gastrointestinal (GI) tract that makes up the digestive system includes all of these organs other than the liver, pancreas, and gallbladder, which are digestive accessory organs that food does not have to pass through to be broken down (The Digestive Sytem and Body Metabolism). The study of this system is called gastroenterology which broken down translates to the study (ology) of the stomach (gastro-) and intestines (entero-) (The Digestive Sytem and Body Metabolism).

The three parts of the small intestine, the duodenum, jejunum, and ileum extend all the way from the pylorus to the beginning of the large intestine or colon (The Digestive Sytem and Body Metabolism). The small intestine is where the majority of nutrient absorption occurs (The Digestive Sytem and Body Metabolism). Peristalsis in the small intestine mixes the food with the digestive juices from the pancreas, liver, and intestine (Diseases). Then the walls of the intestine absorb the digested nutrients into the bloodstream so that the blood can deliver the nutrients to the rest of the body (Diseases). This is the final digestion process of proteins and starches but the bacteria that are in the small intestine only produce some of the enzymes needed to digest carbs (Diseases). The remaining liquid waste is pushed from the end of the small intestine into the beginning of the large intestine, the cecum, after it is processed (The Digestive Sytem and Body

    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

  • Digestive System Vs Circulatory System

    498 Words  | 1 Pages

    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.

    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.

    The digestive systems functions are to digest food, absorb any end products that were digested (including vitamins and minerals). The physiological processes of the digestive system are ingestion, propulsion, mechanical breakdown, digestion, absorption and defecation. Mechanical digestion means to use force in order to break down food for example the use of chewing or the contraction of muscles. Chemical digestion is when the food is broken down chemically into smaller particles such as the use of the saliva in the mouth.

    This is a combination of different set of organs which changes whatever we eat or drink in things that the body uses for growth, energy and repair. The body usually absorbs the nutrients, after the food has been broken down by different chemical processes, the rest is normally expelled as waste product. This whole process can usually take up to several hours or less. The digestive system is also known as the alimentary canal or the gastrointestinal tract. (Tucker L. 2005).

    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 digestive system is important for breaking down food and turning it into nutrients. The body uses the nutrients for energy, growth, and cell repair. The food and drinks that a person must be changed into smaller molecules of nutrients before the blood absorbs them and carries them to cells throughout the body. The body breaks down nutrients from food and drink into carbohydrates, protein, fats, and vitamins. Compared to the other systems in the body, the digestive system is one of the most diverse and important. According to Robert Sullivan the digestive system is a set group of organs whose function is based on the process of turning food, absorbing nutrients for energy and getting rid of the bodies waste (Sullivan, 2008, p.33).

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.
