Hormonal Regulation of Blood Vessels
- Vasopressin (also known as antidiuretic hormone, ADH) causes vasoconstriction of the visceral arterioles.
- Norepinephrine is a powerful vasoconstrictor of arterioles, but has little effect on veins.
- Epinephrine causes vasoconstriction of all capillaries and arterioles, including coronary ones.
- Dopamine can induce either vasoconstriction or vasodilatation depending on the condition.
- Acetylcholine causes vasodilatation of arterioles in skeletal muscles and liver.
