Central vasodilation refers to the widening of blood vessels in the central part of the body, particularly in response to various physiological signals. This process helps to decrease blood pressure and increase blood flow to vital organs. It often occurs during situations such as exercise or heat exposure, where the body needs to regulate temperature and enhance oxygen delivery. Central vasodilation is primarily mediated by the nervous system and the release of certain hormones.

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.
Does sympathetic peripheral vasodilation increase blood volume and BP?
Sympathetic peripheral vasodilation typically leads to a decrease in blood pressure (BP) rather than an increase, as it causes blood vessels to widen, allowing blood to flow more easily and reducing vascular resistance. Consequently, this can result in a decrease in overall blood volume in the central circulation, as blood is redistributed to the peripheral tissues. Therefore, sympathetic peripheral vasodilation does not increase blood volume or BP; rather, it can lead to the opposite effect.
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'.
