00:00:08,740 --> 00:00:13,460
Good morning! We start a new unit today, unit number five, circulatory system.

2
00:00:14,580 --> 00:00:17,620
Remember that you need to write the title and then...

3
00:00:21,219 --> 00:00:25,059
Yes, don't forget table of contents, please. It's really, really important.

4
00:00:25,059 --> 00:00:35,539
Now, we write the first point of our unit. Point number one, extracellular fluid.

5
00:00:36,259 --> 00:00:42,100
we have a lot of fluids inside our body for example one fluid is the one that we have inside

6
00:00:42,100 --> 00:00:48,259
ourselves that would be the intracellular fluid but what are the extracellular fluid think about

7
00:00:48,259 --> 00:00:59,890
it what are the fluids the liquids that we have all around our body okay some clue one of these

8
00:00:59,890 --> 00:01:07,329
fluids transports the carbon dioxide the oxygen and nutrients all around the body yes it's the

9
00:01:07,329 --> 00:01:13,170
blood okay there are other two which are the interstitial fluid and the lymph that we are

10
00:01:13,170 --> 00:01:19,010
going to study the three of them but then we need to write the definition of it so first yeah

11
00:01:19,010 --> 00:01:25,010
extracellular fluid table of contents then we take a piece of paper we take a piece of paper

12
00:01:25,010 --> 00:01:31,329
and on the bottom part we take 10 centimeters okay 10 centimeters wide

13
00:01:32,209 --> 00:01:41,409
and a sorry 10 centimeters long this is 10 centimeters and the the white is 10 centimeters

14
00:01:41,409 --> 00:01:49,569
and the whole upper part of the paper okay so we cut this piece after cutting

15
00:01:49,569 --> 00:01:57,250
we're gonna take seven centimeters here on this part okay and we are going to make these flaps

16
00:01:57,250 --> 00:02:07,250
This will be 10 centimeters that we cut as an arrow shape.

17
00:02:07,250 --> 00:02:10,250
So the arrow here that I have made.

18
00:02:10,250 --> 00:02:16,250
I have made three arrows for all the different definitions that we need to write.

19
00:02:16,250 --> 00:02:22,250
And here, on this part, we write with all the fluids.

20
00:02:22,250 --> 00:02:43,110
the fluids so extracellular fluids extracellular fluids and we have three of them we have first

21
00:02:43,909 --> 00:03:17,750
interstitial fluid the second one blood plasma and the third one lymph you can use different

22
00:03:17,750 --> 00:03:27,189
colors to make it more beautiful color here around okay and inside when we open we're gonna write

23
00:03:27,509 --> 00:03:36,389
the definition get ready to copy interstitial fluid body fluid between blood vessels and cells

24
00:03:36,389 --> 00:03:44,550
containing nutrients from capillaries and waste products discharged out by cells blood plasma

25
00:03:45,189 --> 00:03:51,590
liquid part of the blood that carries cell and proteins throughout the body lymph

26
00:03:51,590 --> 00:03:58,030
fluid formed from interstitial fluid that flows through the lymphatic system.

27
00:03:58,650 --> 00:04:03,449
When you finish writing all the definition, then you have to glue it on your nose.

28
00:04:03,629 --> 00:04:10,430
Remember, underneath extracellular fluid and in a way that we can open and close our flaps.

29
00:04:12,210 --> 00:04:15,569
Underneath our flaps, rewrite the following terms.

30
00:04:15,569 --> 00:04:22,829
homeostasis what is homeostasis is the self-regulation of the body imagine for

31
00:04:22,829 --> 00:04:29,649
example that we are in a summer day okay a summer day and it's really really hot

32
00:04:29,649 --> 00:04:35,550
okay it's really hot what does our body do we start to sweat okay we start to

33
00:04:35,550 --> 00:04:41,790
sweat we feel that we are thirsty that we need to drink water that process of

34
00:04:41,790 --> 00:04:46,889
regulating our own temperature is a part of the homeostasis, but it's not only

35
00:04:46,889 --> 00:04:51,870
about temperature, there are other things. So, what does homeostasis regulate?

36
00:04:51,870 --> 00:05:06,459
Homeostasis is the regulation of three things. Regulation, first of all, of

37
00:05:06,459 --> 00:05:18,939
of temperature as the example that i told you about what happens in a sunday water content

38
00:05:24,339 --> 00:05:30,019
if we drink a lot of water we need to go to the toilet pretty soon because we cannot have too

39
00:05:30,019 --> 00:05:37,139
much water in our body and if we don't have enough water we feel thirsty and carbon dioxide level

40
00:05:37,860 --> 00:05:46,980
co2 levels and it's really bad to have really high in carbon dioxide level because the start process

41
00:05:46,980 --> 00:05:55,300
that we don't really want in our body so usually we start breathing faster for example or try to

42
00:05:55,300 --> 00:06:04,949
get more oxygen inside our body so that is homeostasis and that's all for today remember

43
00:06:04,949 --> 00:06:10,470
please see this table of contents and the reds will be fine. Have a good morning!
