00:00:01,000 --> 00:00:10,679
Nervous systems

2
00:00:10,679 --> 00:00:14,679
The nervous systems carry out the function of sensitivity,

3
00:00:14,679 --> 00:00:19,679
what means it receives and interprets information from the environment.

4
00:00:19,679 --> 00:00:23,679
It gives orders for our body to respond to stimuli.

5
00:00:23,679 --> 00:00:31,629
It controls and coordinates all the organs and systems in our body.

6
00:00:31,629 --> 00:00:33,630
How it works?

7
00:00:33,630 --> 00:00:37,630
The receptors of our senses capture the stimulus.

8
00:00:37,630 --> 00:00:41,469
The information travels through the nerves till it reaches the brain.

9
00:00:41,469 --> 00:00:47,009
The brain receives and interprets the information and sees how to respond.

10
00:00:47,689 --> 00:00:50,950
The nerves carry responses from the brain to the muscles.

11
00:00:51,450 --> 00:00:53,689
Our body follows the brain instructions.

12
00:00:55,990 --> 00:00:58,270
Parts of the nervous system.

13
00:00:59,810 --> 00:01:04,750
Central nervous system, where we find the brain and the spinal cord.

14
00:01:04,750 --> 00:01:16,750
Peripheral nervous system, where we find the nerves that carry all the information from the senses to the brain and others from the brain to the body.

15
00:01:24,790 --> 00:01:30,790
Locomotor system. It is formed by the skeletal system and the muscular system.

16
00:01:30,790 --> 00:01:40,790
The skeletal system is a structure that gives our body its shape and it consists of bones and joints, that are where the bones meet.

17
00:01:40,790 --> 00:01:45,790
Ligaments are the organs that hold the bones together in the joints.

18
00:01:45,790 --> 00:01:54,489
The muscles are organs which allow us to move when they change their state and larynx.

19
00:01:54,489 --> 00:02:01,489
We have internal muscles like the heart and the diaphragm, and the skeletal muscles that make the bones move.

20
00:02:01,489 --> 00:02:05,230
Muscles are attached to bones by tendons.

21
00:02:06,390 --> 00:02:08,729
Our body has 206 bones.

22
00:02:09,550 --> 00:02:12,189
Let's name some of the most important ones.

23
00:02:12,930 --> 00:02:21,870
This is the cranium, the clavicle, the ribs, the femur, the tibia, and the fibula.

24
00:02:21,870 --> 00:02:33,870
Our bones meeting the joints that are the shoulder, the elbow, the wrist, and the ankle, and the hip.

25
00:02:33,870 --> 00:02:41,870
Our body has 639 muscles. Let's name the most well-known.

26
00:02:41,870 --> 00:02:49,870
The quadriceps, the quads, the biceps, and that's all.

27
00:02:49,870 --> 00:03:06,750
The digestive system. The digestive system is responsible for the digestive process of the food in the lotions that the body can use.

28
00:03:07,750 --> 00:03:16,750
How it works? It begins in the mouth. We chew the food and it mixes it with saliva. We swallow it and it goes to the fanatics.

29
00:03:16,750 --> 00:03:28,060
It runs down the esophagus.

30
00:03:28,060 --> 00:03:34,060
It reaches the stomach and mixes with the gastric juices.

31
00:03:34,060 --> 00:03:40,060
Then it travels to the small intestine, where it mixes with the bile and the pancreatic juice.

32
00:03:40,060 --> 00:03:44,060
In the small intestine, the nutrients are absorbed.

33
00:03:44,060 --> 00:03:52,060
Next, in the large intestine the water is absorbed, defacing the body through the anus.

34
00:03:59,060 --> 00:04:09,969
Respiration is the process to obtain oxygen that our body needs and to expel carbon dioxide our body produces.

35
00:04:09,969 --> 00:04:19,970
The air enters through the nose, goes to the larynx, travels down the trachea and goes into the bronchioles.

36
00:04:19,970 --> 00:04:24,970
The air runs through the bronchiole and finishes in the air sacs.

37
00:04:24,970 --> 00:04:36,600
And then the gases change and take place in the air sacs.

38
00:04:36,600 --> 00:04:50,579
And then the carbon dioxide runs up and goes from the nose or from the mouth.
