What does vasodilation in the skin and viscera result from?
Vasodilation in the skin and viscera results from the relaxation of smooth muscle cells in blood vessels. This relaxation causes the blood vessels to widen, increasing blood flow to the skin and internal organs. Vasodilation helps regulate body temperature and can occur in response to various stimuli like heat, exercise, or injury.
What is systemic vasodilation?
Systemic vasodilation refers to the widening of blood vessels throughout the body, leading to a decrease in vascular resistance and an increase in blood flow. This can result in a reduction in blood pressure and may be caused by factors such as medications, inflammation, or changes in physiological state.
What promotes vasodilation?
Nitric Oxide
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.
Is the exercise vasodilation?
Yes. As you exercise, the vessels of blood in the muscles dilate and thus the blood flow greatly.

Will Vasodilation result in increased blood flow to a given tissue?
yes
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.

Which is a type of circulatory shock?
Vascular, due to extreme vasodilation as a result of loss of vasomotor tone
How can one enhance vasodilation in the body?
One can enhance vasodilation in the body by engaging in regular physical exercise, maintaining a healthy diet rich in fruits and vegetables, reducing stress levels, and avoiding smoking. Additionally, certain supplements like nitric oxide boosters and foods high in nitrates can also help improve vasodilation.
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 is systemic vasodilation?
Systemic vasodilation refers to the widening of blood vessels throughout the body, leading to a decrease in vascular resistance and an increase in blood flow. This can result in a reduction in blood pressure and may be caused by factors such as medications, inflammation, or changes in physiological state.
Widening of the blood vessels as occurs during exercise is termed?
This is called vasodilation. This is easy enough to remember: "vaso" means "blood vessel"; "dilation" means "to widen".
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.
Which changes in paracrines cause vasodilation?
Changes in paracrines, such as an increase in nitric oxide or prostacyclin release, can cause vasodilation by relaxing the smooth muscle in blood vessel walls and increasing blood flow. These molecules act locally to dilate blood vessels in response to certain stimuli like exercise or inflammation.
