0:00in reference to organs of the digestive
0:02system you have your mouth and then of
0:04course you have your teeth the average
0:06number of teeth that an individual
0:08should have would be 32 which would
0:10consist of 16 at the top 16 at the
0:13bottom
0:14also within the anatomy of the mouth you
0:16can see here you have a soft palate a
0:19hard palate
0:21uh you have tonsils in the back tonsils
0:24are also part of the lymphatic system so
0:27they are a two-parter they work with the
0:29digestive system as an accessory organ
0:31and then they also work with your
0:33lymphatic system in helping to build
0:36your immunity
0:38you have this uvula here in the back
0:41here as well and what you can't see in
0:44the photo are your salivary glands which
0:46are located underneath the tongue to
0:48help keep the mouth moist and also help
0:51with this term here mastication which is
0:54chewing you have your pharynx and your
0:57esophagus as part of your digestive
0:59system organs as well pharynx is known
1:02as the throat passageway between the
1:05mouth and the esophagus and the pharynx
1:07is also a two-parter because it is also
1:10part of the respiratory system now here
1:12in red you have the esophagus and you
1:15can see in the picture here the
1:16esophagus is the tube that connects the
1:19mouth to the stomach so when food passes
1:22through it's passing through the
1:24esophagus which is a nice flexible like
1:27tube and it uses that wet Wave light
1:30contraction known as peristalsis in
1:32order to push the food through the
1:34esophagus where it will land into the
1:37stomach and go through the exact same
1:39process of churning in peristalsis where
1:42the food will then make its way through
1:43the intestines for absorption now your
1:46stomach uh your stomach's primary
1:48responsibility is to receive food from
1:51the esophagus uh the average size adult
1:54stomach is about the size of a deflated
1:56football so that should give you a
1:58really good idea as to the size of your
2:01stomach it does have what's called
2:03gastric juices inside which help with
2:05digestion and the digestion also
2:08utilizes this term here which is called
2:10ruge and you can see the Rouge here
2:13which is gastric Folds
2:16so going back to that term uh churning
2:19and peristalsis all of that is occurring
2:22with the gastric folds doing the work
2:24stomach is also located in the upper
2:27left quadrant
2:29just as similar as our heart uh and
2:33again this is why oftentimes you will
2:35have patients complain of or have a
2:38chief complaint where they may relate
2:40the pain that they're experiencing to
2:42their heart when essentially it's the
2:44stomach it could be something as simple
2:46as acid in the stomach and the patient
2:48may think that they're having a heart
2:50attack because of the level of
2:51discomfort they're experiencing the
2:54heart and the stomach actually sit very
2:56close together so both sit more on the
2:59left side going down from the stomach
3:02you can see here you have your large
3:04intestine your small intestine the
3:07rectum and at the end of the rectum
3:09would be the anus that is the last
3:11portion of the alimentary canal you do
3:14have what's called accessory organs also
3:17and those accessory organs would be the
3:20liver the gallbladder and the pancreas
3:22you've probably heard of individuals
3:25having their gallbladder removed the
3:28gallbladder does have a response
3:29possibility it is an accessory organ
3:32doesn't mean that you don't necessarily
3:34need it it does have a function however
3:36your body does know how to sustain
3:39without it
3:40little different from the liver and the
3:43pancreas
3:44liver's primary responsibility is to
3:47produce bile and bile is needed to be
3:50able to break down the fats that we take
3:52in
3:53location of the liver would be right
3:56upper quadrant if you think about the
3:59quadrants of the stomach go right upper
4:01quadrant that's where the liver would be
4:03located
4:05now the pancreas the pancreas is
4:07connected to What's called the duodenum
4:10and the duodenum is going to be a
4:12portion of the intestine pancreas's
4:15primary function is to produce an enzyme
4:18that aids in the process of digestion
4:21moving down even further we're going
4:23into What's called the small intestine
4:25and notice here the small intestine is
4:28the main site for absorption of
4:30nutrients so what that means is that
4:33everything that we take into the stomach
4:35goes through that churning and
4:37peristalsis uh chemical and mechanical
4:39breakdown of foods our body takes in the
4:43nutrients that we've then digested and
4:46it's going to absorb that within the
4:48small intestines
4:49your small intestines are divided into
4:52three sections and so the duodenum I
4:55mentioned the Jade junum is here and
4:58then you also have the ilium which is
5:01highlighted in green
5:03so duodenum J Unum ilium all part of the
5:07small intestine small intestine is going
5:09to be the main site for absorption of
5:12nutrients
5:13moving on you have your large intestine
5:16and the large intestine is refers to as
5:19your colon anytime you hear the term
5:22colon think large intestine transverse
5:25colon descending colon ascending colon
5:28large intestine IE colon
5:31colon is also responsible for absorption
5:34of nutrients but then has a second
5:36responsibility because this is where
5:38feces or waste is built up
5:42just like the small intestine the large
5:44intestine is also broken up into
5:46sections and so you have the cecum
5:49uh you have the ascending colon the
5:53transverse colon descending colon and
5:57the sigmoid colon all of these are parts
6:00of the large intestine
6:03and the second is going to be at the
6:05very very end where the appendix is
6:09located and this is your appendix here
6:12appendix is part of the digestive system
6:16but also looked at as an accessory organ
6:19uh and it's part of the lymphatic system
6:21as well because it does assist with your
6:23immunity so here's an up close look at
6:27the appendix here and again at the end
6:29of the large intestine or the cecum
6:33very thin causes a lot of trouble for
6:36something to be as small as it is it can
6:39become overwhelmed at times because it
6:42serves as a reservoir for what's called
6:44beneficial bacteria beneficial bacteria
6:48is going to be healthy bacteria and
6:51sometimes unfortunately the appendix
6:54becomes appendicitis which is an
6:57inflammation of the appendix even though
6:59the bacteria that it's housing is good
7:01bacteria we cannot have an overwhelming
7:04response good bacteria being released
7:07into the body and so when appendicitis
7:09occurs and it's something that is
7:11causing a great deal of pain and also
7:14looks like it may be on the verge of
7:16rupturing the appendix then needs to be
7:18removed now it's causing problems
7:21so part of the immune system helps the
7:24body fight disease and that's going to
7:25be in our young children because what
7:27happens is over time as we age our
7:30immunity is then built for us it's
7:33already set there's not a whole lot we
7:35can do to add to it and so there's no
7:37purpose for it after a while
