1. REGULATION OF BLOOD PRESSURE

2. MABP = CO x TPR Mean Arterial Blood Pressure

3. 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.

4. 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.

5. 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.

6. CO = HR x SV Cardiac Output

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

8. 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.

9. Branched Blood Vessel

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

11. 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

12. 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.

13. 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

14. Vasodilation & Vasoconstriction

15. Hemorrhage

16. VR = BV/VC Venous Return

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

18. 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.

19. 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.

20. Stroke Volume SV = EDV – ESV

21. End-Diastolic Volume = The volume of blood in the ventricle at the end of filling.

22. Stroke Volume SV = 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.

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.

25. Response to Decreased MABP 1. Venoconstriction 2. Increased Contractibility 3. Increased Heart Rate 4. Vasoconstriction
