00:00:10,480 --> 00:00:16,100
Hello everyone, as you can see I do not have my blackboard today

2
00:00:16,100 --> 00:00:21,679
So I'm going to use a piece of paper to explain you what we're gonna do with our notebooks

3
00:00:21,679 --> 00:00:27,140
So you're supposed to have something like this

4
00:00:27,140 --> 00:00:30,519
I see, I think, I ask in your notebook

5
00:00:30,519 --> 00:00:35,200
Okay, so under this we write title number one

6
00:00:35,200 --> 00:00:38,380
Human nutrition number one

7
00:00:38,380 --> 00:00:54,570
sorry if it moves yeah i'm on my table what can i do human nutrition where do we need to write it

8
00:00:54,570 --> 00:01:07,299
yeah okay now we are going to make this flap okay to write the definition of nutrition so basically

9
00:01:07,299 --> 00:01:17,640
Cut a piece of paper, has to be long, so has to be about the large of white paper, okay?

10
00:01:18,000 --> 00:01:24,540
And this would be about, I don't know, 8 centimeters, 5 to 8 centimeters, okay?

11
00:01:24,900 --> 00:01:34,079
And outside you write nutrition and inside exchange substances.

12
00:01:34,079 --> 00:01:39,439
Why? Because in nutrition, we get things inside our body and we get things outside our body.

13
00:01:39,879 --> 00:01:43,799
And inside, there's the definition, so get ready to copy.

14
00:01:57,329 --> 00:02:02,069
After copying the definition of nutrition, we're gonna make this outline.

15
00:02:02,709 --> 00:02:04,629
Let me explain.

16
00:02:04,629 --> 00:02:19,099
so in the nutrition we have different systems in our body we have four different systems in

17
00:02:19,099 --> 00:02:43,949
our body so we have the digestive respiratory circulatory and excretory four different systems

18
00:02:43,949 --> 00:02:52,949
okay let's go with the digestive what is its purpose okay this is purpose we have four

19
00:02:52,949 --> 00:03:16,659
the digestive systems introduce prepare and transform food in the body the respiratory

20
00:03:16,659 --> 00:03:25,659
system obtains o2 oxygen from the environment and eliminates carbon dioxide yeah respiratory

21
00:03:25,659 --> 00:03:27,259
is also part of nutrition.

22
00:03:27,900 --> 00:03:28,460
And finally,

23
00:03:29,460 --> 00:03:30,439
circulatory.

24
00:03:44,780 --> 00:03:46,819
The circulatory system is the one that

25
00:03:46,819 --> 00:03:49,159
transports nutrients,

26
00:03:49,979 --> 00:03:50,979
oxygen, and

27
00:03:50,979 --> 00:03:51,979
waste products.

28
00:03:52,539 --> 00:03:53,759
And the excretory.

29
00:03:54,419 --> 00:04:06,689
The excretory is the system that releases

30
00:04:06,689 --> 00:04:08,710
the waste outside our body.

31
00:04:09,169 --> 00:04:10,990
Digestive, respiratory, circulatory,

32
00:04:10,990 --> 00:04:13,030
and excretory

33
00:04:13,030 --> 00:04:14,430
systems.

34
00:04:34,029 --> 00:04:38,029
in point number two we're going to start studying the digestive system

35
00:04:38,029 --> 00:04:41,470
first of all we're going to study the digestive processes

36
00:04:41,470 --> 00:04:44,750
so the different processes that take place what do you do the digestion

37
00:04:44,750 --> 00:04:52,189
to do so we need to prepare a pop-up yes so let me explain you how we're gonna do it

38
00:04:52,189 --> 00:04:58,430
do you remember when you were a kid or not you prepared a pajarita okay so the first thing we

39
00:04:58,430 --> 00:05:03,870
need to do is to make square in case you forget i show you here how you have to fold the paper

40
00:05:03,870 --> 00:05:11,389
to do a square then you need to fold the square that you have made in order to make the center

41
00:05:11,389 --> 00:05:20,350
of it when you make the center then you take each of the corners its peak and place it on the middle

42
00:05:20,350 --> 00:05:29,709
with that we have a flap so it can open and closed on it you can later glue it on the notebook or

43
00:05:29,709 --> 00:05:36,829
wait until we write everything but don't lose it and we are going to write the different processes

44
00:05:36,829 --> 00:05:46,649
of digestion of the digestive processes which are ingestion digestion absorption and finally

45
00:05:46,649 --> 00:05:58,860
defecation next day we'll write everything inside our pop-up today we have enough bye
