The nervous system. The nervous system carries out the reaction of the sensitivity. What it means? It receives and interprets information from the environment. It gives orders for our body to respond to stimuli. 00:00:00
It controls and coordinates all the organs and systems in our body. 00:00:23
How it works? 00:00:31
The receptors of our senses capture the stimulus. 00:00:33
The information travels through the nerves till it reaches the brain. 00:00:39
The brain receives and interprets the information and decides how to respond. 00:00:44
The nerves carry response from the brain to the muscles. Our body follows the brain structures. 00:00:50
Parts of the nervous system. Central nervous system, where we find the brain and the spinal cord. 00:01:01
Peripheral nervous system, where we find the nerves that carry all the information from cells to the brain and order from the brain to the body. 00:01:08
This is an automatic movement. Your brain controls your moment and you can stop it. 00:01:20
This is a reflex movement. The reflex movement is a movement that we interpret by our environment. 00:01:42
We can't stop it and it's controlled by our spinal cord. 00:01:51
This is a voluntary movement. 00:01:56
The locomotor system is formed by the skeletal system and the muscular system. 00:01:58
The skeletal system is the structure that leads to our body shape and it consists of bones and joints. 00:02:22
There are where the bones meet. Ligaments are the organs that hold bones together in the joint. 00:02:29
The muscles are organs that allow us to move different parts of the body. 00:02:37
body they can change its shape and length we have internal muscles like the head and the diaphragm 00:02:42
and skeletal muscles that make our bones move our muscles are attacked with bones by tendons 00:02:52
our body has 206 bones i'm gonna name one of the most important bones 00:03:02
The cranio, the clavicle, the sternum, the spine, the ribs, the radius, the pelvis, the femur, the fibula and the tibia. 00:03:12
Our bones meet at joints that are the leg, the knee, the ankle, the hip, the wrist, the 00:03:44
elbow and the shoulders. 00:03:57
He has 639 muscles. 00:04:05
I'm going to tell you some of the most important. 00:04:17
Frontalis. Our body has 639 muscles. I'm going to tell you some of the most important. Frontalis, deltoid, pectorals, biceps, quadriceps, and the gluteus anterior. 00:04:22
Hello to everyone, we are going to talk about the digestive system. 00:04:43
The digestive system is responsible for digestion. 00:05:02
That is the process of breaking down food into nutrients that our body needs. 00:05:05
How it works? 00:05:10
It begins in the mouth, we check the food and it mixes with saliva. 00:05:11
We swallow it and it is pushed into the farm. 00:05:19
It runs down the esophagus. 00:05:24
When it reaches the stomach it mixes with gastric juice. 00:05:27
Then it travels to the small intestine. 00:05:32
In the small intestine it mixes with bile and the pancreas juices. 00:05:35
And in the small intestine it absorbs all the nutrients. 00:05:41
Next, spend a large and fast time the water is absorbed. 00:05:46
Finally, the feces leave the body through the anus. 00:05:50
Respiratory system 00:05:55
Respiration is the process to obtain oxygen our body needs to expel the carbon dioxide. 00:06:05
It has two steps. 00:06:12
Inflation 00:06:15
We breathe the air through the nose, goes to the pharynx, travels through the larynx. 00:06:16
the trachea and the bronchi to the lungs. 00:06:22
In the lungs, when the air runs, the bronchi reach the air sacs, 00:06:26
where the gas exchange takes place. 00:06:31
Our body absorbs the oxygen and expels the carbon dioxide. 00:06:35
Exhalation. The carbon dioxide runs up all the way to the nose and mouth. 00:06:41
That's a joke. When the air breaches the air sac, the blood absorbs the oxygen and expels the CO2. 00:06:49
