Gastrointestinal Tract (GIT) Report_2
INTRODUCTIONGastrointestinal tract is an organ system responsible for transporting and disgestingfoodstuff along with expelling waste.The tract consists of all the structures between mouth andanus.Food in the gastrointestinal tract (GIT) plays an important role in the human body. It explainswhich food item is necessary for the better health and different age groups as well. It is alsoimportant for the better skin and also reduces the negative impact of lot of diseases. Gastrointestinaltracts is responsible for the transporting and food stuffs. It also consists of the stomach andintestines (Dan, Li and Jie, 2014). On other hand, it is also divided into two parts which coverslower and upper gastrointestinal. Present report is based on the food items in the gastrointestinaltract (GIT) which is essential outside the body and also the structure and functions to absorb thenutrients in human body (Finestone and Greene-Finestone, 2003).Function of the GIT in absorb the nutrients in the foodThe time taken for food or other ingested objects to transfer via the gastrointestinal tractdepends on different factors (Gomes, Hookway and Weekes, 2014). But in reality, it takes less thanan hour after consumption of meal for 50% that was contents in stomach to empty into theintestines. The whole process takes around 2 hours to process of food. Subsequently, 1 to 2 hoursrequires 50% in emptying of the small intestine. Finally, transit through the colon takes 12 to 50hours with wide variation between individuals. The major function of GIT is immune function inwhere it prevents immune components functioning from entering the blood and lymph circulatorysystems. This protection is provided by the intestinal mucosal barrier (Gordon and et.al, 2004). It isa combination of physical, biochemical, and immune elements. For example, low pH which isranging from 1 to 4 of the stomach is important for many microorganisms that enter into it. With thehelp of it, enzymes are developed in the saliva and bile (Martineau and et.al, 2005).On the other hand, immune system homeostasis are also protected by gastrointestinalsystem. It defines the relationship between human gut and Clostridia. It is the one of the mostpredominant bacterial groups of the digestive system in human body (Takahata and et.al, 2011).Clostridia play an important role in influencing the dynamics of immune system in the gut. Becauseof this, intake of a high fiber diet could be responsible for the induction of Treg cells. The largeintestine hosts several kinds of bacteria which deal with the molecules otherwise it will break downinto the human body (Takahata and et.al, 2011). For example, symbiosis, it is accountable for theproduction of gases at host-pathogen interface inside intestine. Along with this, large intestineabsorption water from digested material and re absorption of sodium (Takahata and et.al, 2011). Itgrows health-enhancing intestinal bacteria to prevent the overgrowth of potentially harmful bacteria3
