Does hypertension increase peripheral resistance?
Blood pressure increases with increased cardiac output, peripheral vascular resistance, volume of blood, viscosity of blood and rigidity of vessel walls.
How does cardiac output blood volume and peripheral resistance affect BP?
In summary, any increases in cardiac output (HR and/or SV), blood viscosity or total peripheral resistance will result in increases in BP.
What is the relationship between peripheral resistance and blood pressure?
In the arterial system, as resistance increases, blood pressure increases and flow decreases. In the venous system, constriction increases blood pressure as it does in arteries; the increasing pressure helps to return blood to the heart.
How does peripheral resistance affect diastolic pressure?
Thus, an increase in systemic resistance results in a rise in diastolic blood pressure. If the elasticity of conductance vessels decreases, diastolic run-off also decreases and diastolic blood pressure goes down.
What causes increase in cardiac output and peripheral resistance?
The amount of friction the blood encounters as it flows through the blood vessels. Three things that can increase peripheral resistance are. Constriction of blood vessels, increased blood viscosity. Any factor that increases either cardiac output or peripheral resistance also causes an increase in.
What causes an increase in peripheral blood pressure?
Three things that can increase peripheral resistance are Constriction of blood vessels, increased blood viscosity Any factor that increases either cardiac output or peripheral resistance also causes an increase in Blood pressure Factors that can alter blood pressure
Which is the highest systolic or diastolic blood pressure?
The pressure the blood exerts against the inner walls of the blood vessels Blood pressure is highest The large arteries Blood pressure is lowest Venae cavae Systolic and diastolic The two blood pressure measurements that depend on the peak ventricular contraction and the relaxation of the ventricles
What causes lack of blood supply to the heart?
Lack of adequate blood supply to the heart muscle; can be caused by blood clots Atherosclerosis Hardening of the arteries Myocardial infarction The death of muscle cells due to lack of oxygen; heart attack Hypertension High blood pressure 140/90
