What are the causes of increased blood flow resistance?

summary

The resistance of blood flow in blood vessels is called blood flow resistance. In the case of turbulence, each particle in the blood constantly changes the direction of flow, so the energy consumption is more than that of laminar flow, and the resistance of blood flow is larger. What are the causes of increased blood flow resistance? Next, I'd like to share my views with you.

What are the causes of increased blood flow resistance?

Blood lipid deposition, blood viscosity increases, leading to smaller diameter of blood vessels, increased resistance! The resistance of fluid flowing in blood vessels is called blood flow resistance. The production of blood flow resistance is due to the consumption of energy due to friction in blood flow, which is generally expressed as heat energy.

This part of heat energy can not be converted into potential energy or kinetic energy of blood, so the pressure of blood flow in blood vessels gradually decreases. In the case of turbulence, each particle in the blood constantly changes the direction of flow, so the energy consumption is more than that of laminar flow, and the resistance of blood flow is larger.

The diagnosis can be made by Hemorheology examination. The resistance of blood flow is directly proportional to the length and viscosity of blood vessels, and inversely proportional to the fourth power of the radius of blood vessels. Because the length of blood vessel changes little, the resistance of blood flow is mainly determined by the diameter and viscosity of blood vessel.

matters needing attention

Drink more water, quit smoking, pay attention to eating habits, develop a good life. Choose foods that dilute the blood. Celery, containing acidic antihypertensive components, has obvious antihypertensive effect, mainly through the aortic arch chemoreceptor to play antihypertensive effect, which is good for patients with hypertension
