00:00:00,000 --> 00:00:03,000
vamos a falar do aparato respiratório

1
00:00:05,000 --> 00:00:08,000
O aparato respiratório se carga do oxígeno

2
00:00:08,000 --> 00:00:11,000
e despulsa do trióxido e do carbono que reproducimos

3
00:00:14,000 --> 00:00:16,000
A boca e as fuses nasales

4
00:00:17,000 --> 00:00:20,000
Estas forman unha cavidade dentro do nariz

5
00:00:20,000 --> 00:00:23,000
e comunican con o exterior

6
00:00:23,000 --> 00:00:25,000
através dos dois agúxeros nasales

7
00:00:26,000 --> 00:00:29,000
A farínxa, a larínxa e a tráquea

8
00:00:29,000 --> 00:00:32,000
forman un conducto que parte das fuses nasales

9
00:00:32,000 --> 00:00:35,000
recorren o interior do cuello

10
00:00:35,000 --> 00:00:38,000
e se adentran no tórax

11
00:00:45,000 --> 00:00:48,000
Os brancos

12
00:00:55,000 --> 00:00:58,000
Os brancos son os tubos nos que se realiza a tráquea

13
00:00:58,000 --> 00:01:01,000
e a sú vez

14
00:01:01,000 --> 00:01:04,000
se pasan por

15
00:01:07,000 --> 00:01:10,000
e se dividen en miles de tubos

16
00:01:10,000 --> 00:01:13,000
cada vez

17
00:01:13,000 --> 00:01:16,000
en un alve

18
00:01:19,000 --> 00:01:21,000
Os alveolos

19
00:01:21,000 --> 00:01:24,000
son diminutos sacos rodeados por

20
00:01:24,000 --> 00:01:27,000
sacos sanguíneos

21
00:01:30,000 --> 00:01:31,000
Os pulmones

22
00:01:31,000 --> 00:01:34,000
Os pulmones son dos órganos esfujosos

23
00:01:34,000 --> 00:01:37,000
que mantén as ramificaciones dos brancos e dos alveolos

24
00:01:37,000 --> 00:01:40,000
E aquí terminamos a exposición
