What promotes vasodilation?
Nitric Oxide
Where in the body would you find low oxygen levels causing vasoconstriction and high levels causing vasodilation?
Low oxygen levels cause vasodilation in systemic arterioles.High oxygen levels cause vasodilation in capillaries in the lungs.
Vasodilation with exercise will result in?
Increased heart rate.
What does vasodilation in the skin and viscera result from?
relaxation of smooth muscle in the arterioles
What controls the diameter of the arterioles and what do changes in diameter affect?
Arterioles are the smallest vessels of the arterial system, with a diameter of about 1/3 millimeter or smaller. There is much smooth muscle in their tunica media, which causes vasocontrictionwhen it contracts, and vasodilation when it relaxes. Such vasoconstriction and vasodilation plays two important roles in the cardiovascular system.controls of distribution of blood flow to different parts of the bodydetermines the total peripheral resistance
When is vasodilation bad?
Never. Unless you're bleeding, but if you're bleeding the body will undergo vasoconstriction not vasodilation so the answer is never.
What causes vaodilation?
Corticotrpin is the harmone which increases vasodilation in our body. alcohol causes vasodilation
What effect does vasodilation have on blood pressure?
Vasodilation causes a drop in blood pressure.
What reduces cardiac afterload?
vasodilation, anemia, cirrhosis, shock states (results in massive vasodilation)
What are the effectors that cause vasodilation and vasoconstriction?
Muscles in the blood vessels are the effectors that cause Vasodilation and Vasiconstriction.
Briefly explain what vasodilation is?
Vasodilation is the widening of blood vessels resulting from relaxation of the muscular wall of the vessels. Usually occurs during exercise, so that more oxygenated blood can be pumped to the body's tissues. Vasodilation is the widening of blood vessels resulting from relaxation of the muscular wall of the vessels.

How do you describe a vasodilation mean?
Vasodilation means the widening of blood vessels that results from relaxation of the muscular walls of the vessels.
What promotes vasodilation?
Nitric Oxide
What are the symptoms of vasodilation?
Vasodilation is the widening of the blood vessels. The common symptoms are low blood pressure, dizziness, flushing, and light headedness.
Where in the body would you find low oxygen levels causing vasoconstriction and high levels causing vasodilation?
Low oxygen levels cause vasodilation in systemic arterioles.High oxygen levels cause vasodilation in capillaries in the lungs.
The redness and heat of an inflamed area are due to a local hyperemia caused by?
chemicals released by the injured tissue cells and leukocytes cause the VASODILATION of the arterioles in the injured area and cause the local hyperemia to form accounting for the redness and heat.
Is there a difference between vasodilation and vasodilatation?
None.'Vasodilatation' is technically the correct term for increase in diameter of lumen of blood vessels.In fact, there is no such term as 'vasodilation', but it is a very common mistake that people use the term 'vasodilation' instead of 'vasodilatation'.
