The Carol of the Pulmonary Capillary.........

The Carol of the Pulmonary Capillary
(tune “Do You Hear What I Hear”)
Written by: Dr. Kent Van De Graaff

Said the trachea to the little lung
“Do you see what I see?
In this body warm, little lung.
Do you see what I see?
Some blood, some blood running through a vein,
Wanting oxygen to gain, wanting oxygen to gain”
 
Said the little lung to the bronchioles,
“Do you hear what I hear?
Coming from the heart, bronchioles,
Do you hear what I hear?
The AV valves closing happily,
It’s time for systole, It is time for systole”
 
Said the bronchioles to the alveoli,
“Do you know what I know?
In your tiny sacs, alveoli
Do you know what I know?
RBC’s are bringing CO2
They wish to exchange gas with you
They wish to exchange gas with you.”
 
Said the alveoli to the molecules,
“Listen to what I say.
Little oxygen molecules,
Listen to what I say.
Squeeze through my simple squamous epithelium
Then grab on to a hemoglobin
Then grab on to a hemoglobin.”
