Final answer:
Peripheral Vascular Resistance (PVR) greatly impacts cardiovascular health through its influence on blood flow and blood pressure. Increased resistance due to factors such as decreased blood vessel diameter or increased blood viscosity can lead to health conditions like hypertension. Moreover, disorders like arteriosclerosis that increase resistance and pressure in blood vessels can have adverse cardiovascular health effects.
Step-by-step explanation:
Vascular Peripheral Resistance and Its Impact on Physical Health
Peripheral Vascular Resistance (PVR) is an essential aspect of maintaining blood flow and blood pressure in the body. Factors affecting blood flow and blood pressure such as cardiac output, blood volume, blood viscosity, and the length and diameter of the blood vessels greatly influence it. Should there be any disorder that affects these factors, it is likely to affect vascular homeostasis.
Altering the resistance in the blood vessels can have critical health effects. For instance, hypertension and shock conditions can result from blood volume disorders or changes in vascular tone. These conditions mainly result from the systemic circulation's resistance and blood flow related issues. For instance, vasoconstriction, which increases resistance and decreases blood flow, can pave the way for hypertension.
The precise balance of vasodilation and vasoconstriction, collectively called vascular tone, is the definitive factor of resistance and flow in blood vessels. Thus, any situation that causes a decrease in the diameter of blood vessels or increase in blood viscosity is likely to increase resistance and reduce flow, impacting health adversely.
Finally, cardiovascular health can be significantly impacted by irregularities in PVR. Conditions like arteriosclerosis resulting from reduced compliance of arteries can cause hypertension and coronary heart disease, as pressure and resistance within the vessels increase affecting cardiovascular health negatively.
