How does blood vessel elasticity affect blood pressure?
Besides, how do blood vessels control blood pressure?
Arteries control blood pressure by balancing two processes: one that constricts the artery wall and another that relaxes it. But in people at risk of developing high blood pressure or atherosclerosis, there is more constriction, impeding the free flow of blood, which increases the risk for heart attack and stroke.
Secondly, how does blood vessel diameter affect the blood pressure of a person? To understand how vessel elasticity, blood volume, and cardiac output affect blood pressure. Vessel diameter affects peripheral resistance. As a the diameter of a tube gets smaller, a greater proportion of the fluid is in contact with the wall of the tube. Therefore resistance to flow is increased and pressure rises.
Correspondingly, what is the importance of blood vessel elasticity?
Inhibits platelet aggregation and the adherence of circulating blood cells to blood vessel walls. As a result it reduces clotting. Decreased monocyte (white blood cell) migration (into smooth muscle cells) which is the beginning of the atherosclerotic process. increases oxygen supply.
What are 3 internal factors that can alter a person's blood pressure?
Factors That Influence Blood Pressure
- Cardiac output.
- Peripheral vascular resistance.
- Volume of circulating blood.
- Viscosity of blood.
- Elasticity of vessels walls.
