Hello friends! 00:00:00
Welcome to a new Happy Learning video! 00:00:09
Today we are going to learn about the circulatory system of the human body. 00:00:11
The main function of the circulatory system is to carry, through the blood, the nutrients 00:00:21
to the cells of our body. 00:00:27
It is formed by the heart, arteries and veins, and its proper functioning is essential for 00:00:29
us to have good health. 00:00:35
I have a curiosity, do you know how much all of the arteries and veins would measure together 00:00:40
put in single file? 00:00:47
They would measure 96,000 km, which would be equivalent to almost two and a half laps 00:00:49
of the Earth. 00:00:56
It's incredible, right? 00:00:57
The heart has the main role in making sure that the blood travels around the body. 00:01:00
With its 100,000 pulsations per day, it ensures that blood circulates throughout our body, 00:01:06
allowing it to distribute oxygen and nutrients into our cells. 00:01:12
We are going to start a journey through the circulatory system, so we can understand it 00:01:18
much better. 00:01:23
The journey of blood begins in the heart. 00:01:24
With the pulsations of the heart, the blood comes out through one of the greatest highways 00:01:27
of the circulatory system, called the aorta. 00:01:32
From that moment, blood flows through our body, through many veins. 00:01:37
During this trip, the blood is delivering oxygen and nutrients to the cells through 00:01:44
the capillaries. 00:01:49
It reaches the neck, head and brain through one side. 00:01:52
From there, the blood continues to flow into our arms, then through the aorta, around the 00:01:57
thorax and abdomen, and finally reaching both of our legs. 00:02:03
As this trip is circular, that is to say, it has no end, the blood starts the trip back 00:02:09
to the heart to regain nutrients and oxygen. 00:02:14
The blood that returns from the lower part of the body flows through the inferior vena 00:02:19
cava. 00:02:25
The one that returns from the arms and head travels through the superior vena cava. 00:02:27
All that blood reaches the lungs, where it gets oxygenated and returns back to the heart. 00:02:34
There, the journey starts again. 00:02:41
The truth is that it is incredible that blood is permanently traveling inside our body, 00:02:44
don't you think? 00:02:51
Well, now you know a little bit more about the circulatory system. 00:02:53
But before saying goodbye, we want to remind you that for our body to work well, we have 00:02:58
to do a lot of physical exercise and have a balanced diet. 00:03:03
You have to eat vegetables, fruit and fish, and reduce eating sugar and sweets as much 00:03:08
as you can. 00:03:14
And of course, spend less time sitting in front of the TV or the computer. 00:03:15
So now you all know. 00:03:21
Right, now everyone, go to run and jump! 00:03:22
Goodbye friends! 00:03:26
Oh, and do not forget to subscribe to Happy Learning TV. 00:03:27
