|---|---|---|---|---|---|
| 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
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
