Question
Chapter 25, Problem 5TYR
Summary Introduction
Introduction:
The renal tubule is a passage that begins from the glomerular capsule and ends at the medullary pyramid. It is divided into four major regions as proximal convoluted tubule, nephron loop, distal convoluted tubule and collecting duct. Each of these regions has characteristic physiological properties and functions in the process of urine production.

Which glomerular arteriole is larger, and why?
the efferent, because it increases hydrostatic pressure in the glomerulus
the efferent, because it increases colloid oncotic pressure in the glomerulus
the afferent, because it increases hydrostatic pressure in the glomerulus
the afferent, because it increases colloid oncotic pressure in the glomerulus

reabsorption.
secretion.
