Question
Chapter 19, Problem 12RQ
Summary Introduction
To determine: The three solutes which are secreted into the lumen of the tubule.
Introduction: Tubular secretion is the opposite process to reabsorption. The transfer of solutes from peritubular capillaries to the tubular lumen is called the tubular secretion.
