Question: Draw A Tube On A Page, Running Top To Bottom. This Tube Is Meant To Represent The Gut, With The Mouth At The Top. Add Divider Lines To This Tube So You Can Label The Main Regions: Mouth, Pharynx, Esophagus, Stomach, Small Intestine, Large Intestine. Pro Tip: Make Sizes Proportional To Physiologic Interest, Not Anatomy … So The Pharynx And Esophagus …

Draw a tube on a page, running top to bottom. This tubeis meant to represent the gut, with the mouth at the top. Adddivider lines to this tube so you can label the main regions:mouth, pharynx, esophagus, stomach, small intestine, largeintestine. Pro tip: Make sizes proportional to physiologicinterest, not anatomy … so the pharynx and esophagus can be tiny;while the stomach and small intestine get more of thespace.

With labeled arrows, show where along the tract each ofthe following would be found: external anal sphincter,gastroesophageal sphincter, internal anal sphincter, pyloricsphincter.

On the left side of the drawing, in the space marked offfor each segment, name the major inputs that the tract or accessoryorgans add to the gut contents in that segment. Include importantgut and accessory organ secretions and enzymes.

On the right side of the drawing, in the space markedoff for each segment, show what materials are absorbed from the gutinto the body fluids in that segment. You should show the mainnutrients (sugars, amino acids, fats), ions, and water. Whenmultiple gut segments absorb one component, show the component inevery region that is a major absorber of it.

Mark all segments of the tract where an abundance of gutmicrobes is normal. Do this by drawing a little microbe next to thename of each applicable segment. Label your microbe, sinceotherwise they just look like random little shapes.
