There are several medications and innate substances that can cause vasodilation (increase in the diameter of the blood vessels). Some of these include Cialis (yes, one of the drugs for erectile dysfunction), nitrates, adrenaline and electrical stimulation of the blood vessel wall muscles.
What else can I help you with?
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.
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.
Does histamine cause blood vessels to contract?
No it causes them to dilate (vasodilation)
What is relaxation of the smooth muscle in the artery wall which causes the artery wall to become larger?
Vasodilation
What effect does vasodilation have on blood pressure?
Vasodilation typically leads to a decrease in blood pressure. This is because when blood vessels dilate, their diameter increases, allowing more blood to flow through them with less resistance, reducing the pressure on the vessel walls.
Does the sympathetic nervous system primarily cause vasodilation or vasoconstriction in the body?
The sympathetic nervous system primarily causes vasoconstriction in the body.
Why doesn't vasodilation work in saunas?
Vasodilation occurs in response to increased body temperature to help dissipate heat. In a sauna, the external heat already causes the blood vessels near the skin to dilate, which is why further vasodilation is limited. This helps maximize blood flow to the skin surface for heat dissipation.
What is thefunctionof thevascular phasein the acuteinflammatoryprocess:?
Vasodilation of the small blood vessels at the site of iniury.in leaking into tissue spaces and causes swelling and pain
Why does the permeability of blood vessels increase during acute inflammation?
vasodilation causes increased pressure within the blood vessel which causes gaps within endothelium to form-this allows for the increased permeability.
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 reduces cardiac afterload?
vasodilation, anemia, cirrhosis, shock states (results in massive vasodilation)
