Digestive System Travel Guide

Anatomy Travel berth welcomes you to Your digestive System pic Kaitlynn Daseke-Col permitte Anatomy and Physiology The Digestive System This locomote your astir(predicate) to go done may c t kayoed ensemble for up to some(prenominal) mean solar days. I expect youve packed well. We go away be going through seas, red-hot rains, and ironic, desert like conditions. So without cachexia each more than time allow me give you a play by play of your vacation premier(prenominal) midriff Our low gear pulley block go forth be breakfast after you wake up on day one. You will be able to eat what ever your smell desires. Anything from a stack of pancakes to something completely uncorrelated to breakfast, like pizza.Choose wisely, you will be stuck with your breakfast for the rest of the tour pic This is where I hand it over to your breakfast applaud your trip pic Hello at that place Im that stack of banana pancakes you devoured at breakfast this dayspring. Our real prototy pical stop on this voyage through your digestive system is the mouth. The mouth is a fine obvious place on the body. So when you put me in your mouth this dawning I met up with some expectoration and so I was chewed excessively know as masticated. Your cheeks and lips hold your sustenance in your mouth while your teeth take c argon of the masticating.The lingua is what helps mix nourishment and saliva to bring somewhather and it in addition initiates swallowing. The transition of digestion has already begun believe it or not. This is the first step in breaking fargon d protest. Although this may sound a elfin gross its not skilful about breaking down provender for digestion, we have tiny buds on our tongue which Im sure you all know as TASTE BUDS taste perception buds argon the taste receptors allowing you to taste the butter, banana, sirup and what ever else you put on me this morning before we began this journeyBefore we get any further and you be uneffective to hear me lets bonnie go through all the expert stuff so we can genuinely enjoy the sites Our second stop on this fascinating trip will be the Pharynx. Two passageways that are most usually taken are the oropharynx and laryngopharynx. on that point is also the nasopharynx. Which when your body was under development we agree to divide and it now currently belongs to the respiratory system, its lovable of like their own private door. But not to worry, youre not missing such(prenominal) First we will go through the oropharynx which leads to the laryngopharynx which will lead us to the esophagus.You talent life a little bit of a squish here and there from the muscularity layers of the pharynx walls. They contract to help act us to the esophagus, this is also called peristalsis. The Esophagus This is also known as the gullet. It runs most hours of the day from the pharynx through the diaphragm to the deport (its about 10 inches/25 cm long). Before we get any further I should probably let you in on this one thing. The walls of the nutritious canal organs (esophagus to grown bowel) are made up of basically the alike(p) types of tissue layers. The first would be mucous membrane, its the innermost layer. Its a damp membrane that lines the cavity (lumen). Mucosa has heighten epithelium, a menial amount of connector tissue and a bit of unagitated muscle. Second we have submucosa which as you might be able to pellet is prime beneath the mucosa. Its basically a connective tissue that turn outs blood vessels, facial expression endings, lymphnodules and lymphatic vessels. Theres a muscle layer made up of an inner, circular layer and an outer longitudinal layer of basically adept brush up muscle cells, this is called the muscularis externa. Serosa is the outermost layer of the wall. This is a single layer of plain serous fluid that produces cells. Visceral Peritoneum makes slick parietal peritoneum. Parietal peritoneum lines the abdominopelvic c avity by mesentery (way of a membrane extension). The walls also contain important intrinsic spirit plexus, I know your thinking you move intot know what that is, to be honest neither am I. But I think it might be kind of important to know that there is two, the submucosal nerve and the myentreric nerve plexus. Theyre actually a part of the autonomic nervous system.There that there to regulate the mobility and secretory action of GI (Gastrointestinal) tract organs. pic Alright, third stop. The endure. It is primed(p) on the left side of the abdominal cavity. Here we will be hidden by the liver and diaphragm. There are a few places around the stomach you might want to stop and see. The first is the cardiac region, as you might guess it was named this due to its position near the heart. It surrounds the cardioesophageal sphincter which is where we will have entered the stomach. The fundus is the expanded part, in truth roomy, you should probably stretch your legs here, move a round.Its lateral to the cardiac region. The body then is the midportion and as it narrows it turns into the pyloric antrum. Then of dustup the funnel graded pylorus which is the part that is dogging with the small intestine. Interesting Facts about the raise Approx. 10 inches Diameter depends on how much feed its holding A bounteous stomach can hold about 4 liters/1 gallon of food From the stomach we will enter the small intestine through the pyloric sphincter. This is the major digestive organ. It prepares usable food for the journey into the cells of the body.The small intestine is anywhere from 8 to 18 feet long in a living person. Its kind of a tube made of muscle and it just extends from where we entered to the ileocecal valve. At the small intestine there are tether places I propose taking a peak at. Duodenum performer 12 finger widths long. Jejunum ( release) Ileum (twisted intestine) this also joins the large intestine at the ileocecal valve. Most of your food digestion occurs in the small intestine and it is more than qualified to do so. The walls of the small intestine have three structures that help tremendously with absorption.These three are the microvilli, villi, and circular folds. The microvilli are tiny projections of the plasma membrane of the mucosa cells that make the cell surface cipher fuzzy. The villi are fingerlike projections they have a velvety appearance and also encounter soft. This is where a lot of the absorption occurs. There are also circular folds that are deep folds of mucosa and submucosa layers. ?Villi Believe it or not by the time you are done looking around these three sites and seeing the microvilli, villi and circular folds we will be on our way already through the ileocecal valve to the large intestine.So grab your stuff and let us go take a look see. The Large Intestine though its larger in diam it is shorter than the small intestine. The large intestine runs about 5 feet long. These 5 feet are f rom the ileocecal valve to the anus. The chief(prenominal) function of the large intestine is to dry out the food residue that cannot be digested. It does this by absorbing water and in conclusion eliminates the residues from the body as feces. The large intestine is divided into 5 subdivisions. They are 1. The Cecum, its bursiform and the first part of the large intestine. 2.The Appendix, which hangs from the cecum, its very wormlike and sometimes because of its shape it can cause issues like appendicitis. This happens when the addendum becomes inflamed. 3. The colon which has several regions that takes you through the pelvis. 4. The rectum lies in the pelvis between the sigmoid colon and anus. 5. The anus, this is the part where feces exit the body. The anus is where our journey together will end. I hope you enjoy this journey through out the digestive system and come linchpin to visit again real soon pic Without any further explanation, please comply me through the pharynx
