2.2.9-2.2.11 - Systolic & Diastolic Blood Pressure

Systolic Blood Pressure

• The force exerted by blood on arterial walls during ventricular relaxation

• The force exerted by blood on arterial walls during ventricular contraction

• Movement of blood through the vessels

• Force that opposes the flow of a fluid

Diastolic Blood Pressure

• The force exerted by blood on arterial walls during ventricular relaxation

• The force exerted by blood on arterial walls during ventricular contraction

• Movement of blood through the vessels

• Force that opposes the flow of a fluid

Flow

• The force exerted by blood on arterial walls during ventricular relaxation

• The force exerted by blood on arterial walls during ventricular contraction

• Movement of blood through the vessels - related to SV & HR

• Force that opposes the flow of a fluid

Resistance

• The force exerted by blood on arterial walls during ventricular relaxation

• The force exerted by blood on arterial walls during ventricular contraction

• Movement of blood through the vessels - related to SV & HR

• Force that opposes the flow of a fluid

Which of the following represents normal blood pressure?

• 100/60mmHg

• 120/80mmHg

• 140/90mmHg

• 160/100mmHg

What immediate response can we expect when someone begins running at a moderate intensity?

• Increase in Systolic Blood Pressure

• Increase in Diastolic Blood Pressure

• Decrease in Systolic Blood Pressure

• Decrease in Diastolic Blood Pressure

Blood Pressure will increase with an:

• Increase in stroke volume

• Increase in heart rate

• Decrease in stroke volume

• Decrease in heart rate

Blood pressure will be lower with:

• Lower compliance of blood vessels

• Lower volume of blood

• Greater compliance of blood vessels

• Greater volume of blood

With an increase in blood viscosity there will be an:

• Decrease in peripheral resistance & increase in blood pressure

• Increase in peripheral resistance & decrease in blood pressure

• Increase in peripheral resistance & increase in blood pressure

• Decrease in peripheral resistance & decrease in blood pressure

The length of a blood vessel is directly proportional to its resistance

• True

• False
