Final answer:
Vasodilation refers to the widening of blood vessels resulting in a stronger peripheral pulse, while vasoconstriction, the narrowing of blood vessels, leads to a weaker pulse.
Step-by-step explanation:
Vasodilation and vasoconstriction are two processes that result in changes in the diameter of blood vessels, which can be detected as changes in the Peripherial Pulse. Vasodilation occurs when blood vessels widen. This process reduces vascular resistance and pressure but increases blood flow. During vasodilation, the pulse may feel stronger and more easily detected due to the increased blood flow. On the other hand, vasoconstriction refers to the narrowing of blood vessels, which increases vascular resistance and pressure but decreases blood flow. The peripheral pulse recording might show a weaker pulse when vasoconstriction occurs, as less blood is passing through the narrowed vessels.
In summary, vasodilation coincides with a stronger and potentially quicker peripheral pulse due to increased blood flow, while vasoconstriction might result in a weaker pulse due to decreased blood flow. These changes may also reflect compensatory mechanisms in response to alterations in blood pressure, as the body attempts to regulate and maintain homeostasis.
