Hi guys, today we're going to learn about the
0:21
circulatory system of the human body.
0:24
Remember that all living beings
0:26
perform three vital functions to
0:32
interaction, and reproduction. Through
0:39
necessary substances to live and perform
0:41
the other vital functions.
0:46
digestive, respiratory, circulatory, and
0:49
excretory systems are involved in this process. But as we said at the
0:52
beginning of this video, today we're going to
0:54
talk a little more about the circulatory system. The
0:58
circulatory system is where
1:01
blood circulation occurs. The
1:04
main function of the circulatory system
1:06
is to transport and distribute
1:09
nutrients and oxygen to all the
1:12
cells in our body. It is also
1:14
responsible for transporting the waste products
1:17
generated by the cells to the excretory system.
1:20
The circulatory system is composed
1:23
of blood, blood vessels, and the
1:31
red liquid that transports nutrients
1:33
and gases throughout our body so that
1:36
it functions correctly.
1:38
Within the blood, we can find
1:41
three types of cells: red blood cells,
1:44
which are responsible for transporting
1:46
oxygen; white blood cells, which
1:49
defend us against many diseases; and
1:52
platelets, which are... Pieces of cells that
1:56
blood vessels when an injury occurs.
1:59
Blood vessels are the conduits through
2:02
which blood circulates.
2:04
There are three types of blood vessels:
2:07
arteries, which carry blood from the
2:10
heart to the rest of the body; veins,
2:15
back to the heart from the
2:17
different organs; and capillaries, which
2:20
are the finest blood vessels and
2:23
connect arteries and veins. Their function is to
2:26
facilitate the delivery of substances carried
2:31
body's cells. Did you know
2:33
that the heart is primarily responsible for
2:36
blood circulation throughout our body?
2:38
The heart is a muscle
2:42
located in the center of the chest, towards the
2:45
left side, which, with its more than 100,000
2:47
daily beats, ensures that
2:50
blood circulates throughout our
2:53
body, guaranteeing the distribution of
2:55
oxygen and nutrients to all
2:58
cells. Internally, it is divided into four
3:01
chambers: two atria and two
3:04
ventricles. The atria receive
3:08
body's organs, and the ventricles pump
3:11
blood to the organs. The
3:15
ventricles are separated by
3:19
blood to flow from the atria to the
3:21
ventricles and prevent backflow.
3:23
According to the World
3:25
Health Organization, diseases of the
3:28
circulatory system are the leading cause of
3:31
death worldwide. Some of the most
3:33
common are high cholesterol and
3:40
Preventing diseases of the
3:42
circulatory system is possible by adopting a
3:45
series of habits to take care of our
3:47
health, such as not overindulging in
3:50
fats, reducing salt intake, and
3:53
following a balanced diet to
3:55
prevent being overweight; avoiding a
3:57
sedentary lifestyle and exercising
4:00
regularly to strengthen the heart
4:04
washing and disinfecting wounds to
4:07
prevent bacteria from entering and
4:09
causing a more serious infection; and not smoking or
4:12
drinking alcohol or other substances
4:16
Want to know an amazing fact? Do
4:19
you know how long all the veins and
4:23
arteries together would be? If we laid them end to end, they would
4:25
measure approximately
4:28
97,000 kilometers. That's
4:40
Let's see if you understood.
4:42
Our round of questions begins. The
4:46
first question... It produces in the
5:01
the circulation of the blood
5:04
bravo guys let's go for the next one
5:07
what three elements make up the circulatory system
5:22
the circulatory system is made up
5:26
of the blood the blood vessels and the
5:29
heart do you remember good job
5:33
champions let's go for the last one who is
5:36
mainly responsible for the
5:38
blood traveling through our body time
5:51
the heart phenomenal that was easy
5:56
well done guys you have done an
5:59
excellent job I hope you have
6:03
learned a lot of things with this
6:06
video you can watch it again as many times
6:09
as you need see you in the
6:12
next video until next time
