Why is the heart so important
The Human Body: The Heart | Educational Videos For Kids
[Music]
hello friends welcome to new happy
learning video today we're going to get
to know the engine in our body today
we're going to get to know the human
heart
[Music]
the heart is the most special muscle we
have it situated a little to the left
from the center of our chest between our
lungs and is in an oblique position
position diagonally we say that it's
very special because it sends blood all
over our body blood delivers oxygen and
nutrients weaning to live - all of our
cells a heart is a type of pump
like the ones we used to inflate the
wheel on our bikes the only thing is
that instead of pumping air it spawns
but the Hutt's is divided into two parts
the right part and the left part
separated by a cellular wall so they are
not connected internally each one of
these parts has two chambers or cavities
the upper cavities are called right and
left atrium and the lower cavities are
called a right and left ventricle the
heart also has full kind of doors which
are called valves these valves open lets
blood in and they close so this blood
carts go back now we've got to know the
most important parts of the heart but do
you know how it works it's all commences
in the right atrium where the
deoxygenated blood meaning it has very
little oxygen and nutrients enters the
heart then it goes through the first
foul back to the right ventricle once it
is here the heart sends the blood down
directly to the lungs and it's in this
moment where the blood is oxygenated and
it's filled with oxygen and nutrients
when it is already oxygenated it goes
back to the heart reaching the left
atrium from where it will pass through
the third valve until the last cavity
the left ventricle finally the heart
sends this now oxygenated blood through
the fourth and last valve towards the
rest of the body and it starts again
to understand how our heart beats we
only need to imagine that our hand is a
heart and that's when it opens up it
fills up with blood and when it's closed
its pumps that blood outwards when blood
exits our heart it flows through a whole
body through blood vessels and there are
three types arteries veins and
capillaries vessels arteries deliver
oxygen and nutrients rich blood to all
our organs in our body veins take that
blood low in oxygen back to the heart
and the capillary vessels which are very
small connected arteries with veins and
cells fun fact
do you know approximately how much a
human heart weighs well it's 450 grams
almost half a kilo the truth is that's
the heart is the engine in our
circulatory system and there's an
incredibly strong muscle it's able to
beat more than a hundred thousand times
a day so cool we can't say goodbye
without giving you a tip we need to take
care of our heart and that's why we need
to do physical exercise we need to eat
healthy foods and please never ever
smoke it's the worst thing you can do to
hurt your heart
goodbye friends see you in the next
happy learning video
