Hello again! We're going to continue with our anatomy of the digestive system. Last day we 00:00:01
studied the mouth, the esophagus and the stomach. Today we're going to continue with some glands 00:00:07
related to the digestive system, liver and pancreas and we continue our journey through 00:00:14
the small and large intestine. Let's start! We start with the liver and pancreas. So 00:00:20
you need to write the title on your notebook, remember the left side of your 00:00:36
notebook, and we're going to use this picture that you have on the paper that 00:00:41
I gave you in class, okay? This picture we cut it and we glue it on our notebook. 00:00:48
And now we're going to learn some more about liver and pancreas, so everything I 00:00:56
right on the board, you're going to write it on one side or underneath the picture. 00:01:01
The liver is a gland that has a very important function in our system. We're going to study now 00:01:10
the function of the digestive system. Basically, the liver secretes the bile. And what's the 00:01:16
bile? The secretion of the liver, but it doesn't go directly to the intestine, but before it passes 00:01:22
to the gallbladder, which in Spanish is vesícula biliar. There it stays until the digestion takes 00:01:31
place and then it's secreted to the duodenum. The function of the bile is to act as a detergent to 00:01:39
lipids. What does it mean? That the lipids are going to be in the duodenum and then the bile 00:01:50
comes and it goes all around the lipids and helps to digest them. The pancreas. The pancreas secretes 00:01:56
pancreatic juices. These pancreatic juices secreted to the duodenum helps to digest 00:02:07
proteins and make proteins smaller to amino acids. On the small intestine you should glue 00:02:14
the following uh the following current of your paper okay if you don't have space maybe you can 00:02:22
fold it a little bit so it can open and close there are some things that you don't need to 00:02:30
learn okay you need to learn the parts of the small small intestine which has the duodenum 00:02:37
the union and ileum and you will need to know the position of it you will need to know that 00:02:43
their intestinal folds okay which are here um and that they have a the shape like fingers that they 00:02:50
get inside the small intestine because they're gonna help with the absorption and this this 00:02:59
picture here is a small section of the big one and in this section there are some things that you 00:03:05
don't need to learn so you can cross it okay starting from here up we have the epithelium 00:03:13
cross absorptive cell enterocyte cross a globet self close cross endocrine cell cross intestinal 00:03:21
gland liver con gland cross cells of planet cross blood capillaries yes yes you need to learn that 00:03:34
where are the blood groups and where it says lactial you instead of that you write lymphatic 00:03:45
vessel and continue crypt cross brush border cross but yes you need to learn the microbial 00:03:52
and villus. Let me tell you about the function of the small intestine. The main function of the 00:04:04
small intestine is absorption. The nutrients that are now really, really small, we get into the 00:04:10
small intestine and the small intestine has a large surface area which is going to help to 00:04:18
absorb the cells in the small intestine has a lot of elongation they are like fingers they have like 00:04:26
small fingers and that increases a lot the surface that the small intestine can absorb substances 00:04:36
so basically the small intestine function is absorption and it has a large large structures 00:04:45
to help with this absorption. Last but not least, we have the large intestine, 00:04:55
the responsible for absorbing water. We have this picture that we're gonna glue 00:05:03
under the title of large intestine on our notebook. We need to learn the 00:05:10
different parts of the large intestine, which are the colon, ascending, transverse 00:05:16
understanding the rectum and also remember that in the large intestine we 00:05:23
have the appendix that is an organ that is responsible for some function of the 00:05:29
immune system one function of the large intestine is to absorb water so we don't 00:05:38
lose too much water in the process of digestion but also it's very important 00:05:44
function of some bacteria which are there which is the gut flora that in spanish we call it flora 00:05:48
intestinal these thanks to these bacteria on one hand we get vitamin k and also they transform 00:05:55
undigested products into feces so without this bacteria we couldn't really live that's all about 00:06:05
the digestive system remember that you will need to learn every single part of the digestive system 00:06:13
the function that it performs and you have to relate all of them with the process of digestion 00:06:20
