CHORUS:
These cells are your cells; these cells are my cells,
From the CD4 cells to the retinal Y cells.
From the haploid gametes to our guest E. coli,
These cells are found in you and me.

When I am running, my knees lift skyward
From the contraction of muscle fibers.
Their sliding filaments support this function,
And these cells are found in you and me.

CHORUS

We have red blood cells with hemoglobin
To carry oxygen where the blood is flowin'.
No organelles here -- just lots of protein,
And these cells are found in you and me.

CHORUS

When the sun is shining, there's nothing better
Than light absorption by photoreceptors.
With their rhodopsin and ion channels,
These cells are found in you and me.
