  1. REGULATION OF BLOOD PRESSURE

  2. MABP = CO x TPR Mean Arterial Blood Pressure

  3. MABP = CO x TPR Mean Arterial Blood Pressure = Average blood pressure in an individual, the overall blood pressure within your body. Mean Arterial Blood Pressure

  4. MABP = CO x TPR 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. Mean Arterial Blood Pressure

  5. MABP = CO x TPR 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. Mean Arterial Blood Pressure

  6. CO = HR x SV Cardiac Output

  7. CO = HR x SV Heart Rate = The number of times the heart is contracting per minute. Cardiac Output

  8. CO = HR x SV Heart Rate = The number of times the heart is contracting per minute. Stroke Volume = The volume of blood ejected every time the heart contracts. Cardiac Output

  9. Branched Blood Vessel

  10. MABP = DP + 1/3(PP) Mean Arterial Blood Pressure

  11. MABP = DP + 1/3(PP) Diastolic Pressure = The minimum pressure in the arteries, which occurs near the beginning of the cardiac cycle when the ventricles are filled with blood Mean Arterial Blood Pressure

  12. MABP = DP + 1/3(PP) 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. Mean Arterial Blood Pressure

  13. MABP = DP + 1/3(PP) 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 Mean Arterial Blood Pressure

  14. Vasodilation & Vasoconstriction

  15. Hemorrhage

  16. VR = BV/VC Venous Return

  17. VR = BV/VC Venous Return = The volume of blood returning to the heart. Venous Return

  18. VR = BV/VC Venous Return = The volume of blood returning to the heart. Blood Volume = The volume of blood in an individual’s circulatory system. Venous Return

  19. VR = BV/VC 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. Venous Return

  20. Stroke VolumeSV = EDV – ESV

  21. Stroke VolumeSV = EDV – ESV End-Diastolic Volume = The volume of blood in the ventricle at the end of filling.

  22. Stroke VolumeSV = EDV – ESV End-Systolic Volume = The volume of blood in the ventricle at the end of contraction and beginning of filling. End-Diastolic Volume = The volume of blood in the ventricle at the end of filling.

  23. 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 =

  24. 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.
