Overview: Gastrointestinal System – Physiology | Lecturio


[Music] to be able to talk through where these occur there are two different kinds of approaches we could take the first approach is the anatomical approach so for this you take in food through the mouth you’ll swallow it into the esophagus it’ll go into the stomach and then the small intestine large intestine then out through the rectum if you didn’t utilize it or absorb it and I like this anatomical viewpoint because it gives us a very nice link to the anatomy but in terms of function I think it’s better to start thinking about this in terms of an engineering point of view so let’s take a look at what that might look like so this engineering tube viewpoint sets up this type of system in kind of a linear format we’ll start off with something like the teeth which will chop up food we will end up adding liquid and adding mucus to lubricate the system and to get the food stuff along the passageways we will have a portion of it that helps blend or grind up the food as well as provide a acid for undergoing certain types of protein characterization will have a certain portion of this engineering tube that will supply detergent a place in which all those reactions can take place and then we’ll have a specific the specific component that we’ll add then enzymes to undergo a lot of the different macronutrient digestion but of course we need to have a spot in which we can absorb all of these particular macro and micro nutrients finally to be able to save water we need out of a place where we can remove water and we can form pellets so that of course we can get rid of certain things that aren’t necessary so this is this engineering tube viewpoint that we’re going to revisit a number of times as we introduce the various components of the gastrointestinal system and I think this functional approach will really help land what kind of things happen what spot okay let’s start linking the two and that is the engineering and the anatomical viewpoints let’s start off with where this detergent is added from and that is done from the liver and from the gallbladder so the liver is going to produce various bile type substances that are stored in the gallbladder and then released into the small intestine so that’s where the detergent is coming from the mouth and teeth provide this kind of initial chopping and grinding of food and why that’s so important is you’re taking large particles making them into smaller particles so there’s more surface area available to undergo digestion but remember to be able to get food down the GI system we need to make sure that it has water added to it and it also is lubricated and that’s done with the salivary glands finally the stomach is the place in which we’re going to help blend and grind food a little bit more and this is where acid is added to the system finally it’s your pancreas that supplies the enzymes to the small intestine and these enzymes include everything from those are involved with carbohydrates fats and proteins the small intestine involves the area in which most all of the action is taking place for digestion and absorption so these are where the enzymes are acting on and where you break these large molecules down into small molecules so that you can absorb them finally the large intestine is where we remove some water and then finally the rectum is of course where we control what is released from the gastrointestinal system [Music]
