00:00:02,930 --> 00:00:03,930
Teacher!

2
00:00:03,930 --> 00:00:04,929
Hello!

3
00:00:04,929 --> 00:00:08,199
Hi!

4
00:00:11,199 --> 00:00:13,199
Are you studying?

5
00:00:13,199 --> 00:00:14,199
Yes!

6
00:00:14,199 --> 00:00:19,199
Okay, so today we are going to review the circulatory system.

7
00:00:19,199 --> 00:00:20,199
Okay.

8
00:00:20,199 --> 00:00:29,199
The first question is, what is the blood and what does it say?

9
00:00:29,199 --> 00:00:37,380
Blood is a liquid that travels through the blood vessels to transport oxygen, CO2, nutrients, and waste products.

10
00:00:37,960 --> 00:00:45,560
Oh well, the second question is, what kind of cells there are in the blood?

11
00:00:47,320 --> 00:00:47,960
I know.

12
00:00:48,799 --> 00:00:50,320
In the blood there are.

13
00:00:50,320 --> 00:00:54,140
The things that stop building when we have our...

14
00:00:54,140 --> 00:00:55,880
The second one is for...

15
00:00:55,880 --> 00:00:57,679
Please, please, please, please, please.

16
00:00:57,740 --> 00:00:58,060
Okay.

17
00:00:59,200 --> 00:01:05,180
Red blood cells, they carry the gases, oxygen and carbon dioxide.

18
00:01:06,079 --> 00:01:09,340
And the third one is for Jorge de Mesa.

19
00:01:09,939 --> 00:01:13,700
White blood cells, they protect the body.

20
00:01:14,599 --> 00:01:17,680
Okay, and the third and last question.

21
00:01:18,359 --> 00:01:22,299
What kind of blood vessels do we have?

22
00:01:22,640 --> 00:01:23,819
What are their functions?

23
00:01:25,579 --> 00:01:25,980
Alberto.

24
00:01:25,980 --> 00:01:40,980
There are three kinds of blue western arctic caribou with oxygen from the hair to the body cells.

25
00:01:40,980 --> 00:01:43,980
Okay, and the second one?

26
00:01:43,980 --> 00:01:57,480
Okay, the second one is veins that carry CO2 to the heart, and the third one is ore.

27
00:01:57,480 --> 00:01:58,480
Anybody know?

28
00:01:58,480 --> 00:01:59,480
No.

29
00:01:59,480 --> 00:02:00,480
No.

30
00:02:00,480 --> 00:02:01,480
So it's capillaries that connect veins with arteries.

31
00:02:01,480 --> 00:02:02,480
Okay.

32
00:02:02,480 --> 00:02:03,480
You need to study more.

33
00:02:03,480 --> 00:02:04,480
Bye-bye.

34
00:02:04,480 --> 00:02:05,480
Bye-bye.

35
00:02:05,480 --> 00:02:06,480
Bye.

36
00:02:06,480 --> 00:02:07,480
Bye.

37
00:02:07,480 --> 00:02:08,479
Bye.

38
00:02:08,479 --> 00:02:09,479
Bye.

39
00:02:09,479 --> 00:02:10,479
Bye.

40
00:02:10,479 --> 00:02:11,479
Bye.

41
00:02:11,479 --> 00:02:12,479
Bye.

42
00:02:12,479 --> 00:02:13,479
Bye.
