this from katznug pharma( almost all vessels contain
endothelial muscarinic receptors that mediate vasodilation
These receptors are readily blocked by antimuscarinic drugs.
At toxic doses, and in some individuals at normal doses, antimuscarinic agents cause cutaneous
vasodilation, especially in the upper portion of the body. The mechanism is unknown)
Epinephrine can cause vasodilation provided the level is low enough. If beta-2 recptors are activated (without the level of epinephrine being high enough to involve the significant numbers of alpha receptors), then the effect of epinephrine on the vascular smooth muscle be relaxation, thus, dilation. However, higher levels of epinephrine will activate alpha receptors which will cause vasoconstriction.
The lungs have this blood flow pattern. Low oxygen levels (hypoxia) cause vasoconstriction to redirect blood flow to well-ventilated areas of the lung, while high oxygen levels (hyperoxia) cause vasodilation to optimize oxygen exchange.
Low oxygen levels causing vasoconstriction would typically occur in the pulmonary circulation, where the body constricts blood vessels in response to low oxygen levels (hypoxia) to redirect blood flow to well-ventilated areas of the lungs. High oxygen levels causing vasodilation can occur in systemic circulation, where increased oxygen levels trigger blood vessel relaxation to optimize oxygen delivery to tissues.
