The Digestive System of the Human Body

1624 Words4 Pages

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.
The digestive system is very responsible for taking the whole food that people eat and turns them into energy and nutrients to allow the body to function, grow, and fix itself. The six primary processes of this system are ingestion of food, secretion of fluids and digestive enzymes, mixing and movement of food and waste throughout the body, digestion of food into small pieces, absorbing the nutrients, and the elimination of wastes. Ingestion is the first function of the digestive system, which is also known as the intake of food. The mouth is the reasoning for this process because through the mouth is the way food enters the body. The stomach and the mouth store food until your stomach is ready to digest the food that was just eaten. The reason why people can only eat a few times a day is because your body can only allow a certain amount of food depending on your body weight and type, and it cannot ingest more food than it can process at one time. The next step in Secretion, this happens in the course of the day. The digestive system secretes about 7 liters of fluid daily, but these fluids include saliva, mucus, hydrochloric acid, enzymes, and bile...

  • The Psychiatric Perspective of Irritable Bowel Syndrome

    1610 Words  | 4 Pages

    Irritable bowel syndrome (IBS) is a functional GI disorder (FGID) characterized by abdominal pain in association with altered bowel habits in the absence of any identifiable structural or biochemical abnormalities. It is a very common disorder that can have a profound negative impact on a patient’s quality of life and constitutes a considerable social and economic burden on society. Extensive research over the last few decades has led to a better understanding of this complex syndrome and improvements in treatment. After a brief review of the clinical manifestations and diagnosis of IBS, the current understanding of the complex physiological mechanisms contributing to the syndrome will be addressed. The remainder of this paper will focus on a number of important topics at the interface of IBS and psychiatry, including psychiatric comorbidity in IBS, the complex role of psychosocial stressors in the onset and perpetuation of symptoms in IBS, and various considerations in the management of IBS from the perspective of psychiatry.

    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.
