WVSOM -- Physio

Systemic Circulation

Pulse Pressure systolic - diastolic
Current = Voltage/resistance
TPR total peripheral resistance
Q= Arterial Pressure / TPR
MAP Mean Arterial Pressure
MAP = Diastolic + 1/3(PP) CO X TPR
80% of total BV is in the ___________ systemic circulation
Most of the blood in the systemic circulation is in the veins
Central BV contains _____% of total BV ~20-25
Central BV is Central vena cava Intrathoracic portions of the inferior vena cava Right atrium and ventricle pulmonary circulation left atrium
CVP central venous pressure
2 ways to alter CBV increase or decrease the total BV OR redistribute the BV you have
MSFP mean circulatory filling pressure
Venous return must equal cardiac output
Right atrial pressure depends on Cardiac Output and Venous return
Venous return determines Right Atrial Pressure
Right Atrial Pressure determines Venous Return and Cardiac Output
Things that shift teh vascular curve up and down are blood volume and venous tone
What happens to MCFP when there is more BV or an increase in VT? increase
Things that can change MCFP SNS tone blood volume contraction of skeletal muscle
Increasing arteriolar resistance __________ venous return increases
Cardiac function curve plots cardiac function as a functino of RAP or CVP
Increased TPR effect on cardiac function and venous return curves Vasoconstriction Lowers CO May shift both cardiac function and venous return curves
Heart Failure effect on the venous return and cardiac function curve Cardiac function goes down and then Venous Return goes up to compensate

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
