Takeaways
- 🧡 The heart is a vital organ in the body, and 'VA' is an acronym to help memorize its structure.
- 🔄 Blood flows from the vena cava to the right atrium, then to the right ventricle, and is pumped out through the pulmonary artery to the lungs.
- 🌀 From the lungs, blood returns via the pulmonary veins to the left atrium, then to the left ventricle, and is pumped out to the aorta for the rest of the body.
- 📍 It's crucial to understand the right and left sides of the heart, with the right atrium and ventricle on the right side, and the left atrium and ventricle on the left side.
- 📋 Memorize the four main chambers of the heart: right atrium, right ventricle, left atrium, and left ventricle.
- 🔍 Arteries carry blood away from the heart, while veins bring blood to the heart; the term 'pulmonary' is associated with the lungs.
- 📝 Practice by drawing arrows between the heart's structures to visualize the blood flow from the body to the heart and back again.
- 📉 The pulmonary artery carries blood from the heart to the lungs, and the pulmonary vein brings it back to the heart.
- 🚫 Valves prevent backflow of blood; the pulmonary valve is in the pulmonary artery, and the aortic valve is in the aorta.
- 🔄 The tricuspid valve is on the right side of the heart, and the mitral valve is on the left side, both preventing backflow from the ventricles to the atria.
- ⏱ The entire process of memorizing the heart's structure can be achieved in under five minutes with the right approach.

Transcripts
hey guys welcome to another video today
I'm gonna be teaching you how to
memorize the structure of the heart and
five minutes so without further ado
let's get into it first of all the heart
is a vital area of the body so memorize
that vital area VA that's the acronym
we're gonna be using but from now let's
take a quick look at the heart and recap
on things right so first of all we're
gonna be taking blood through the vena
cava from the rest of the body and it's
gonna enter the right atrium from the
right atrium it's gonna go to the right
ventricle from here on out it gets
pumped out through the pulmonary artery
to the lungs from the lungs it gets
transported through the pulmonary veins
to the left atrium where the blood makes
its way to the left ventricle where it's
pumped out to the aorta to the rest of
the body where it makes eventually makes
its way back to the vena cava back to
the right side of the heart really
important to know that you can ignore
everything for now but really important
to know that this side of the heart is
the right-hand side and this side of the
heart is the left side of the heart
right so everything is named accordingly
right atrium for example and another
really important thing is for you to
understand that there are four main
chambers and that's what you should
memorize first ignore everything else
memorize the four main chambers the
right and left atrium and the right and
left ventricle some other definitions
the artery will always take the blood
away from the heart that's really
important in the vein will always take
blood to the heart and the pulmonary
worth the book the word pulmonary
basically is always associated with
something to do with the lungs so this
is a very simple exercise that you need
to be confident and doing first of all
right before doing anything else I want
you to be able to write down lungs rest
of the body and these four chambers
right atrium right ventricle left atrium
and left ventricle so what the exercise
is is for you to create arrows going
from one structure to the other every
structure has to have an arrow going
somewhere and obviously it needs to be
create so from the rest of the body is
gonna make its way to the right atrium
making its way to the right ventricle
making us way to the lungs making us way
to the left atrium making its way to the
left ventricle and then making its way
to the rest of the body and he'll now
weave
creating a cycle and so what this means
if you're doing this confidently it
means that you are very well aware of
the blood flow through the heart and
memorizing the diagram becomes a lot
easier when you are aware of the blood
blood flow through the heart okay so I
said before the heart is a vital area on
the body so VA is the acronym that we're
gonna be using so let's start with a
vena cava we know that this is the vena
cava and we're gonna start from there so
from the ven okay we're gonna pinpoint
the main areas that the blood goes
through so from the vena cava V a V a V
a V a so just don't worry about
everything else just label them V's and
AIDS for now okay so it's just VA four
times so the first V is for vena cava
the second a is for atrium the next
videos for ventricle the next a is for
artery the next V is for vein the next a
is for atrium and the next videos for
ventricle and the next a is for a water
okay so we labeled this artery and vein
but we know that this is the pulmonary
artery because there's carrying blood
from the heart to the lungs remember
poner pulmonary is associated with the
lung so it's a carrying blood away from
the heart that's why it's an artery to
the lungs so pulmonary artery and this
is respectively called the pulmonary
vein the next thing that we need to know
is the valves so the economically
contain the valves but you just need to
memorize those separately so let's take
a look at the valves that are inside the
pulmonary artery quite simply it's
called the pulmonary valves and inside
the aorta it's called the aortic valve
pretty simple valves basically just
prevent backflow of the blood and you
should all know you should know that
already right so there are two extra
valves that are separate the atrium and
the ventricle to prevent backflow of
blood from the ventricle back to the
atrium right so on the right side of the
heart developers called the tricuspid
and the left side of the heart the valve
is called mitral but there you go that's
basically everything you need to know
and it's been done under five minutes so
memorize that and you should be sweet
thank you
