1)
Determine left from right by looking at the
thickness of the myocardium
- Left ventricle pumps against more resistance therefore
it needs more muscle power!
2) Determine the valves by looking at their
location
- Are they entering the ventricle? Yes – then they are AV
valves. Knowing the left from the right will help determine
how many flaps the valve has there are
- Are they exiting the ventricles? Yes - knowing left from
right will determine the which semilunar valve it is.

• Left or right side of the
heart?
• How many flaps are
their in the indicated AV
valve?

Figuring out Blood Vessel Anatomy
1)
Identify Surrounding Organs
- This helps determine what blood the vessel is
carrying.
2) What color is the blood vessel
- This will determine the direction of
blood flow
- Red: arteries carry blood away from
the heart
- Blue: veins carry blood to the heart
- Yellow: hepatic portal system carrying
blood to the liver to be detoxified
