Heart is a complex organ of our human body and we must know about its function and processes that happens inside our heart.

1. Hi! I am Rohan. I will help you
explore the amazing world of our
most essential organ that is heart
throughout this journey. So, lets
begin!

2. Label
the
parts
of
the
heart

3. Label
the
parts
of
the
heart
About it !!
Superior and inferior vena cava
De-oxygenated
blood from upper
and lower parts of
the body enters the
heart from superior
and inferior vena
cava respectively.
This deoxygenated
blood enters the
right atrium
/auricle of the
heart.

4. Label
the
parts
of
the
heart
About it !!
Right atrium
The blood from
vena cava enters
the auricle.
The wall of the
atrium is
comparatively thin
from that of
ventricles.
The blood then
passes through the
tricuspid valve and
pours into the right
ventricle of the
heart.

the
heart
About it !!
Right ventricle
Now the blood is
in the right
ventricle. The wall
of the ventricles is
too much thick.
Blood from the
right ventricle
passes on to the
pulmonary artery
through the
pulmonary valve.

6. Label
the
parts
of
the
heart
About it !!
Pulmonary artery
Pulmonary artery is
an exceptional
artery that carries
deoxygenated
blood. The
deoxygenated
blood from
pulmonary artery
goes to the lungs
to be filtered.

7. Label
the
parts

the
heart
About it !!
Pulmonary vein
Pulmonary vein is
an exceptional vein
that carries
oxygenated blood.
The oxygenated
blood from the
lungs comes back
to the heart
through pulmonary
vein after being
filtered. Now, the
task is to pump the
oxygenated blood
to all the parts of
our body.

8. Label
the
parts
of
the
heart
About it !!
Left atrium
And now the blood
is in left
atrium/auricle of
the heart. The wall
of the auricle is
thin. Oxygenated
blood from left
auricle goes to the
left ventricle
through the
bicuspid/ mitral
valve.

9. Label
the
parts
of
the
heart
About it !!
Left ventricle
The blood enters
the left ventricle of
the heart. This is
the chamber of the
heart from where
our body gets
oxygenated blood.
Blood passes on to
the aorta through
the aortic valve
present between
the left ventricle
and aorta.

10. Label
the
parts
of
the
heart
About it !!
Aorta
Eventually, the
blood is ready to
be transported to
our body tissues
and cells. Arteries
carry the
oxygenated blood
to the tissues and
cells.

11. Label
the
parts
of
the
heart
About it !!
Respiration and CO2 release
Tissues and cells
then respire and
carbon dioxide and
energy is released.
The carbon dioxide
from cells and
tissues is carried to
the heart by the
veins that drain in
to the tube which
we call it as vena
cava.

Keep learning
And this process
continues until we
die.
Interesting ! Isn’t it
?
And this comes to
the end of the
slide. Thank you
for sticking with
me till the end.
Take care!!
