Gill Breathing
Gill Breathing
To the tune of “Perfect Day” by Lou Reed
[Verse 1]
Morphological
Limitations will include
Gill thickness
And surface area to
Gill morphology
Cannot be optimized
Due to the
Osmorespiratory compromise
[Chorus]
Gas exchange is limited
By morphological constraints
And physiologically
By partial pressure gradients
By partial pressure gradients
[Verse 2]
Fish will optimize
Their physiology
Through how they
Organize capillaries
Countercurrent flow
Will maintain the gradient
For the
Diffusion of oxygen
[Chorus]
Gas exchange is limited
By morphological constraints
And physiologically
By partial pressure gradients
By partial pressure gradients
[Outro]
Fish gills also will use
Unidirectional ventilation too
O2 levels are not diluted
In respiratory fluid
