1
00:00:02,419 --> 00:00:08,060
to think and they are going to look and explain it.

2
00:00:08,060 --> 00:00:15,859
It is for us to understand better our thinking system.

3
00:00:15,859 --> 00:00:25,579
Basically, we are going to learn how the stomach and the skin work.

4
00:00:25,579 --> 00:00:29,480
The materials that we rip off.

5
00:00:29,480 --> 00:00:33,479
A plastic bag represents the stomach.

6
00:00:33,479 --> 00:00:36,479
A banana represents the food.

7
00:00:36,479 --> 00:00:40,479
Three cookies represent the food.

8
00:00:40,479 --> 00:00:44,479
Orange juice represents the gastric juice.

9
00:00:44,479 --> 00:00:49,479
The water represents the saliva.

10
00:00:49,479 --> 00:00:54,479
A donkey represents the small intestine.

11
00:00:54,479 --> 00:00:59,479
A cat represents the small intestine.

12
00:00:59,479 --> 00:01:10,280
fingers represent the teeth. Our fingers for the food in the summer are the saliva, water and the

13
00:01:10,280 --> 00:01:17,109
But I think it's good.

14
00:01:18,109 --> 00:01:24,069
Like this?

15
00:01:33,230 --> 00:01:34,230
Not too much salt.

16
00:01:36,230 --> 00:01:38,230
Then we mash the food.

17
00:01:49,230 --> 00:01:51,230
Put it in this mold.

18
00:01:58,230 --> 00:02:08,229
We see the nutrients in the small intestine.

19
00:02:08,229 --> 00:02:21,830
The nutrients go to the circulatory system.

20
00:02:21,830 --> 00:02:29,830
Then the waste products go to the large intestine.

21
00:02:29,830 --> 00:02:33,830
And then we eat meat.
