Gill Breathing

To the tune of "Perfect Day" by Lou Reed
Morphological
Limitations will include
Gill thickness
And surface area too
Gill morphology
Cannot be optimized
Due to the
Osmorespiratory compromise

Gas exchange is limited
By morphological constraints
And physiologically
By partial pressure gradients
By partial pressure gradients

Fish will optimize
Their physiology
Through how they
Organize capillaries
Countercurrent flow
Will maintain the gradient
For the
Diffusion of oxygen

Gas exchange is limited
By morphological constraints
And physiologically
By partial pressure gradients
By partial pressure gradients

Fish gills also will use
Unidirectional ventilation too
O2 levels are not diluted
In respiratory fluid
