Which of the following is an effect of histamine?

1.Decreased capillary filtration
2.Vasodilation of the arterioles
3.Vasodilation of the veins
4.Decreased Pc
5.Interaction with the muscarinic receptors on the blood vessels

exp:

Histamine causes vasodilation of the arterioles, which increases Pc and capillary filtration. It also causes constriction of the veins, which contributes to the increase in Pc . Acetylcholine (ACh) interacts with muscarinic receptors (although these are not present on vascular smooth muscle).
