regulation of blood pressure

REGULATION OF BLOOD PRESSURE

MABP = CO x TPR

Mean Arterial Blood Pressure

MABP = CO x TPR

Mean Arterial Blood Pressure

Mean Arterial Blood Pressure = Average blood pressure in an individual, the overall blood pressure within your body.

MABP = CO x TPR

Mean Arterial Blood Pressure

Mean Arterial Blood Pressure = Average blood pressure in an individual, the overall blood pressure within your body.

Cardiac Output = Volume of blood pumped out by the heart per minute.

MABP = CO x TPR

Mean Arterial Blood Pressure

Mean Arterial Blood Pressure = Average blood pressure in an individual, the overall blood pressure within your body.

Cardiac Output = Volume of blood pumped out by the heart per minute.

Total Peripheral Resistance = The combined resistance of a branched artery.

CO = HR x SV

Cardiac Output

CO = HR x SV

Cardiac Output

Heart Rate = The number of times the heart is contracting per minute.

CO = HR x SV

Cardiac Output

Heart Rate = The number of times the heart is contracting per minute.

Stroke Volume = The volume of blood ejected every time the heart contracts.

Branched Blood Vessel

MABP = DP + 1/3(PP)

Mean Arterial Blood Pressure

MABP = DP + 1/3(PP)

Mean Arterial Blood Pressure

Diastolic Pressure = The minimum pressure in the arteries, which occurs near the beginning of the cardiac cycle when the ventricles are filled with blood

MABP = DP + 1/3(PP)

Mean Arterial Blood Pressure

Diastolic Pressure = The minimum pressure in the arteries, which occurs near the beginning of the cardiac cycle when the ventricles are filled with blood

Systolic Pressure = The peak pressure in the arteries, which occurs near the end of the cardiac cycle when the ventricles are contracting.

MABP = DP + 1/3(PP)

Mean Arterial Blood Pressure

Diastolic Pressure = The minimum pressure in the arteries, which occurs near the beginning of the cardiac cycle when the ventricles are filled with blood

Systolic Pressure = The peak pressure in the arteries, which occurs near the end of the cardiac cycle when the ventricles are contracting.

Pulse Pressure = Systolic Pressure minus Diastolic Pressure

Vasodilation & Vasoconstriction

Hemorrhage

VR = BV/VC

Venous Return

VR = BV/VC

Venous Return

Venous Return = The volume of blood returning to the heart.

VR = BV/VC

Venous Return

Venous Return = The volume of blood returning to the heart.

Blood Volume = The volume of blood in an individual’s circulatory system.

VR = BV/VC

Venous Return

Venous Return = The volume of blood returning to the heart.

Blood Volume = The volume of blood in an individual’s circulatory system.

Venous Compliance = The degree to which a vein is capable of distending. Compliant veins have large diameters.

Stroke VolumeSV = EDV – ESV

Stroke VolumeSV = EDV – ESV

End-Diastolic Volume =

The volume of blood in the ventricle at the end of filling.

Stroke VolumeSV = EDV – ESV

End-Diastolic Volume =

The volume of blood in the ventricle at the end of filling.

End-Systolic Volume =

The volume of blood in the ventricle at the end of contraction and beginning of filling.

Frank-Starling Law

The Frank-Starling Mechanism states that the greater the volume of blood entering the heart during diastole, the greater the volume of blood ejected during systolic contraction.

Frank-Starling Law =

Frank-Starling Law

The Frank-Starling Mechanism states that the greater the volume of blood entering the heart during diastole, the greater the volume of blood ejected during systolic contraction.

Frank-Starling Law = Decreasing blood returning to the heart will make the heart contract weaker.

Response to Decreased MABP

1. Venoconstriction

2. Increased Contractibility

3. Increased Heart Rate

4. Vasoconstriction
