Potassium Channels 

ATP Sensitive K Channel

Insulin and Potassium Sensitive ATP channels 

Hypoxia 

First Sign Of Hypoxia When Oxygen Levels are 15-19

Hypoxia acts on Potassium Channels 

Inhibition Of O2 sensitive Potassium Channels = Vasoconstriction 

Opening Of ATP sensitive Potassium Channels  = Vasodilatation 

Hypoxia

Pulmonary Arteries = Vasoconstriction 

Systemic Arteries = Vasodilatation
