| Question | Answer |
| highest resistant in CVS | arterioles |
| largest total cross-sectional and surface area | capillaries |
| veins | under low pressure; high portion of blood |
| arteries | deliver oxygenate blood to tissues; high pressure; stressed volume |
| Systolic pressure | hightest arterial pressure during cardiac cycle; measured after heart contracts and blood ejected into arterial system |
| Diastolic pressure | lowest arterial pressure during a cardiac cycle; measured when Heart is relaxed and blood is returning to the heart via veins |
| Pulse Pressure | determinant of Stroke Volume |
| what can cause increase in PP | aging |
| Pulse pressure calculations | systolic - diastolic |
| arterial pressure is measurement of | Left arterial pressure [PCWP] |
| Ejection fraction measured | Stroke volume / EDV |
| what is normal EF | 55% |
| Preload measured by | EDV and RA pressure |
| Afterload measured by | LV = aortic pressure : increase in aortic pressure = Increase in afterload of LV RV = pulmonary artery pressure; increase in pulmonary artery pressure causes increase in afterload in RV |
| what increases preload | venous dilaters |
| what decreases afterload | vasodilators |
