venodilation is dilation of venules of veins? and what is arteriolar dilation?
Whqt is the difference between venodilation and vasodilation?
As you said, one is referring to arteries and the other is in reference to veins. Considering how blood flow in arteries and veins is very different, they have completely different effects on your body. Your heart and capillaries are affected by both in different ways, and so are the muscles in your blood vessels. In vasodilation, your smooth muscle in the arteries is going to relax and the vessels dilate in circumference, so blood has more room to flow at one time and therefore your blood pressure is decreased. In venodilation, the same thing happens but in the veins. The significance in the difference is that veins are carrying the blood from the rest of your body back to the heart, whereas arteries carry it away from the heart. Imagine the impact this has on your heart and capillaries. With vasodilators, your heart rate will increase because your heart "thinks" it needs to pump more, considering that the vessels coming into it are much smaller than those going out. The opposite is going to happen in venodilation. There are actually drugs that can do both of these, but keep in mind that they're going to directly affect the rest of your body in serious ways and therefore are more fatal.
