Question | Answer |
MAP equals | MAP= DP + (1/3)(SP-DP)
Cardiac output x total peripheral resistance |
Cardiac output equals | Stroke volume x Heart rate |
Stroke Volume includes | EDV and ESV |
EDV refers to | Preload |
ESV refers to | Afterload and Inotropy |
Sympathetic stimulation uses which neurotransmitters | Epi and Norepi |
Do veins have Beta2 receptors? | No |
What percent of total blood volume is in systemic circulation | 80% |
Peripheral resistance is controlled by | arterioles |
Right atrial pressure depends on | Cardiac output and Venous Return |
If you increase Right atria pressure, what happens to venous return | Decrease |
Mean circulatory filling pressure | A measurement of how full the system is- pressure if the heart stopped beating |
Three things that affect the vascular function curve | BV, Capacitance, and Slope of the curve(aka TPR) |
Things that shift vascular function curve up | Increased volume and Increased venous tone |
Things that shift vascular function curve down | Decrease in volume and decreased venous tone |
An increase in venous tone does what to venous capacitance? | Decreases |
Increasing arteriolar resistance does what to venous return | Decreases |
Decreasing arteriolar resistance does what to venous return | Increases |
What happens to mean circulatory filling pressure when arteriolar resistance changes | Nothing |
