Please help! Vasoconstriction or -dilation?

Post by malaxo » Sun Sep 18, 2016 6:11 pm

Hi

I can't seem to wrap my head around this.

"The coronary arteries express more β2 receptors than α1 receptors, and thus will dilate at sympathetic stimulation".

But doesn't the sympathetic signaling result in vasoconstriction? It all seems a bit contradictory to me.

Thanks in advance from Sweden!
