Hello! Do you remember last day we started with the anatomy of the digestive system? 00:00:08
You should have watched the video of the cross course and write all the different functions of the different organs. 00:00:14
You will need to glue this picture also that I gave you in class. 00:00:22
We are going to see now each organ part by part. 00:00:26
You should have now a photocopy with all the different pictures of the different organs that you will have to glue when I tell you. 00:00:31
Let's start. 00:00:38
We start with the first part of the digestion system, the mouth. 00:00:41
What do we do usually with the mouth? 00:00:45
With the mouth, we do the process of ingestion. 00:00:48
Okay, so you should, from the paper that I gave you in class, we told the different parts of the digestive system. 00:00:52
You're going to cut the one of the mouth and the one of the teeth. 00:01:02
And you're going to glue it under the title, okay, and your notebook. 00:01:07
On the mouth, we have different parts of the mouth. 00:01:14
The first are our teeth. 00:01:17
Our teeth have different names depending on the function that they have. 00:01:19
We have the incisors, canines, premolars and molars. 00:01:25
The names you should write them on the paper after you have glued the mouth. 00:01:32
At the back of our mouth we have the uvula, which in Spanish we call it campanilla or uvula. 00:01:37
the uvula helps us to talk and speak. Then what else do we have? We have the tongue, 00:01:47
we have the gums which are the part that fix the teeth to our jaws and we have also the palate 00:01:56
that is on the upper part the upper part of our mouth and the tonsils that maybe you have suffered 00:02:09
from them maybe you sometimes you feel sick because you have the tonsils inflamed and they 00:02:17
are very useful about the teeth you don't need to learn all the different parts of the teeth there's 00:02:24
no need okay but in case you were worried about the teeth maybe you had some problems about the 00:02:32
teeth and you want to learn more about them i have uploaded a video in the i would love you 00:02:38
to all that you can watch it if you want under the two pictures of the mouth and teeth we're 00:02:44
gonna make a pop-up yes pop-up okay we're gonna make a pop-up on one side as you have here in my 00:02:52
notebook okay we're gonna cut a piece of paper which will be eight centimeters times 10 centimeters 00:02:59
and we're going to cut it into three different parts but as you can see i didn't cut it till 00:03:06
the end okay i i left one space where i'm going to glue it to our notebook in the way that we have 00:03:11
flaps okay what are the functions of the mouth there are three of them mastication insalivation 00:03:19
and deglutition we're going to see each of them in mastication imagine that i turn the flap and 00:03:26
I write directly on the notebook. So, what is the purpose of mastication? Tearing, cutting, chewing 00:03:34
and grinding food. When we turn the page, the flag in ensalivation, we need to write that the purpose 00:03:41
of ensalivation is mixing. What does it mix? Grounded food plus saliva. Grounded food means 00:03:50
molido, grounded food plus saliva. And in deglutition, which is the process by which 00:03:58
we get the food from our mouth inside our esophagus we have some peristaltic movements 00:04:05
we're going to see this peristaltic movements also in the esophagus in the intestines okay 00:04:13
we'll study later when you have finished with all this pop-up on one side either the left or 00:04:20
on the right side, I have it for example 00:04:28
here on the right, but it doesn't 00:04:30
matter, okay, we write 00:04:32
the word 00:04:34
bolus. 00:04:35
Why do we write the word bolus? Because 00:04:37
after all the food 00:04:40
is mixed in the mouth 00:04:41
with all the 00:04:44
tearing, chewing, 00:04:45
grinding, etc., and 00:04:48
mixed with the saliva, then it forms 00:04:49
the bolus, and the bolus pass from the mouth 00:04:52
through the esophagus 00:04:54
until it reaches the stomach. 00:04:56
So we don't have food anymore, we have the bolus. 00:04:57
We continue with our journey through the digestive system, we move to the esophagus. 00:05:04
From the mouth, the bolus gets inside the esophagus, which is a large tube that connects the mouth with the stomach. 00:05:10
And the way of passing the bolus from mouth to the stomach is through peristaltic movement. 00:05:18
So, I'm going to play now a picture that you will need to copy on your notebook under the title Esophagus. 00:05:23
You need to copy the following drawing of the peristaltic moment. 00:05:34
last part that we are going to see today is the stomach you have to watch a video which is now 00:05:38
on the aula virtual and you need to fill in the theory that i gave you in class okay you need to 00:06:01
fill in the gaps but this is theory so we need to write it on the left side of our notebooks 00:06:10
