Question
Chapter 15, Problem 5CR
Summary Introduction
To review:
The driving force that is responsible for filtration of fluid into glomerular space from the glomerular capillaries.
Introduction:
The primary force that is responsible for the filtrating the fluid into glomerular space from the glomerular capillaries is high blood pressure. Due to blood pressure, around one hundred and eighty liters of protein devoid plasma is driven across the glomerulus into the glomerular space.
