|
Definition
|
|
Term
| List the three causes of resistance and indicate which contributes the most to total peripheral resistance: |
|
Definition
| Vascular resistance (most), Viscosity, Turbulance |
|
|
Term
| The vessel that has the most impact on changing pressures in the vascular system, and why? |
|
Definition
| Arteriole, 1/2 of the pressure is lost here because of their length and the high number. |
