2. First we have to understand
that while facing a patient
that THEIR left side is YOUR
right side. Patients’ left arm
Doctors’ right arm

3. There are 4 chambers that
blood flows through in your
heart
The Right Atrium
The Right Ventricle
The Left Atrium
The Left Ventricle

4. There are 2 valves that exist
between each Atrium and
Ventricle that close after the
blood is pumped through them
The Right Pulmonary The Left Pulmonary
Atrioventricular Valve Atrioventricular Valve
(Tricuspid Valve) (Bicuspid Valve)

5. These valves help to keep your
blood from flowing back the way
from which it came, by closing
up with each beat. There are also
tiny valves in all the veins and
arteries that serve the same
purpose, called venous valves.

6. There are 3 veins that carry
Deoxygenated Blood into the
heart.
Superior Vena Cava
Inferior Vena Cava
Coronary Sinus

7. Our Journey Begins!
Into the Heart
 Blood flows into the Right Atrium
 Down through the Tricuspid Valve
 Into the Right Ventricle
 Then up through the *Pulmonary
Semi lunar Valve

8. Blood becomes OXYGENATED!
 Blood runs
through
pulmonary trunk
into the lungs
 Then the Blood
runs across the
Alveoli (air
sacks) of the
lungs and picks
up Oxygen

9. REFRESHED!
Back to the heart
 Blood flows via the Pulmonary Veins
 Back into the Heart at the Left Atrium
 Down through the Bicuspid Valve
 Into the Left Ventricle…

10. UP & OUT!
 The Blood then flows through
the Semi Lunar Valve
 Up and out of the heart into
the Aorta

11. And the beat goes on!
There are 3 veins branching
from the Aorta
 Brachiocephalic Artery
 Left Common Carotid Artery
 Left Subclavian Artery

12. Blood goes round and round
 Thus, beginning its journey through the
arteries to deliver oxygen to the cells of
your body
 When the blood in the arteries becomes
deoxygenated they are then recognized as
veins

13. And There You have it!
