Systemic vascular resistance (SVR) is used for what calculations? correct answers Blood pressure
Blood flow
Cardiac function
What is pulmonary vascular resistance (PVR)? correct answers Resistacne the right ventricle must overcome to open the pulmonic valve and eject a volume of blood in the pulmonary vasculature.
What is pulmonarartery occlusion pressure (PAOP)? correct answers The pressure created by the
volume of blood that remains in the left heart at end-diastole.

A prerenal block is: correct answers An interruption on the way to the kidneys.
The intrarenal system correct answers Processes ultra-filtrate by tubular secretion & re-
absorption.
An intrarenal block is: correct answers Direct damage to the kidneys.
The postrenal system correct answers Excretes kidney waste products through the ureters, bladder, and urethra.
A postrenal block is: correct answers Obstruction of urine output.
Causes:
Enlarged prostate
Kidney stones
Bladder tumor
Bladder injury
