Question
Explain the Effects of Active and Passive Mechanisms on Vascular Resistance?
Expert Solution
Step 1
Vascular resistance can be interpreted as the hydraulic force that must be overcome to retain the flow across the vascular bed. , resistance is mostly similar to cardiac input and blood pressure through Ohm's law:
BP = Q × SVR
Where,
BP is blood pressure
Q is cardiac output
SVR is systemic vascular resistance.
