Vasodilation refers to the widening of blood vessels, which increases blood flow and decreases blood pressure. Conversely, vasoconstriction is the narrowing of blood vessels, reducing blood flow and increasing blood pressure. These processes are regulated by the autonomic nervous system and serve to maintain blood flow and pressure within normal limits.
What else can I help you with?
What promotes vasodilation?
Nitric Oxide
Vasodilation with exercise will result in?
Vasodilation during exercise increases blood flow to the working muscles, delivering more oxygen and nutrients for energy production and waste removal. This process helps to improve exercise performance and endurance by enhancing muscle function and reducing the risk of muscle fatigue.
Does sympathetic stimulation cause vasodilation of which arterioles?
Sympathetic stimulation causes vasoconstriction of most arterioles in the body, except for arterioles in skeletal muscle and the heart where it causes vasodilation.

What happens to blood flow when vasodilation occurs?
the red blood cells will dilate meaning just like your eyes dilate your red blood cells will get bigger to get more oxygen to muscles and tissues. as when you run for long periods you will notice your face becoming more red which is a result in vasodilation simply red blood cells but larger.. this also triggers the sweat glands to sweat and then evaporate on your skin to cool down the skin.
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.

What causes vaodilation?
Corticotrpin is the harmone which increases vasodilation in our body. alcohol causes vasodilation
Does sympathetic activity cause vasodilation?
No, sympathetic activity typically causes vasoconstriction, not vasodilation.
What reduces cardiac afterload?
vasodilation, anemia, cirrhosis, shock states (results in massive vasodilation)
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.
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.
Does the sympathetic system cause vasodilation?
Yes, the sympathetic nervous system can cause vasodilation in certain situations, such as during exercise or in response to stress. This is because the sympathetic system releases certain neurotransmitters that can relax blood vessels and increase blood flow to muscles and other tissues.
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.
How does the nervous system's ability to trigger vasoconstriction and vasodilation impact the body's overall physiological response?
The nervous system's ability to trigger vasoconstriction and vasodilation affects the body's physiological response by regulating blood flow. Vasoconstriction reduces blood flow, increasing blood pressure and redirecting blood to vital organs during stress or cold. Vasodilation increases blood flow, helping to cool the body and deliver nutrients during exercise or relaxation. These responses help maintain homeostasis and support various bodily functions.
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.
Does cold have a vasodilation effect?
No, it has a vasoconstricting effect.
