Never Gonna Give You Up (Song Parody)

Lyrics: Ceili Wasson and Sam Whiteley

We are no strangers to blood
You know the systems, and so do I
Circulation's what I'm thinking of
You wouldn't get this from any other guy
I, just want to let you know how I'm pumping
Gotta make you understand.

(Chorus:)
Systole, your pressure's up
Diastole, your pressure's down
Heart pumps the blood around
Diffusion.
First to the arteries
Through to the capillaries
Cells deoxygenate heme
For their use.

We've known each other, for so long.
The heart's been working, but
Its too important to stop
Valves have been closing all day long
You hear the recoil, take the heart rate.
And if ask me how I'm breathing
I'll check my aorta for CO2.

(Chorus)

(Chorus again)

Systole, Systole
Systole, Systole
Diastole
Diastole, Systole
Diastole
Diastole, Diastole

We've known each other, for so long
Your circulation, and breathing too.
Valves have been closing all day long
You hear the recoil, take the heart rate.
I, just want to let you know how I'm pumping
Gotta make you understand.

(Chorus)

(Chorus)
