Continuation of Crit that follows;

Red Cell pas de deux cell-mate pirouette;
Such spinning embrace speeds chemistry set.
And around he goes as around she goes
Strikingly intricate life dance all knows.
Ions conjoin at the speed of light
So life’s lamp is lit all day and all night.
Corpuscles shaped like mounted car tires
Yet twists through paths no auto aspires.
You may wonder why red cells shaped like that;
Evolution’s tryouts the fittest beget.
Spheres and planes sport active surface galore.
Biconcaves though have thirty-percent more.
Man has red cells much more than other type;
To call us “Red Celleans” not just hype.
