Chapter 12, Problem 5SQ
Summary Introduction
Introduction: The kidney is an important organ of the excretory system and nephron is the basic structural unit of the kidney. As blood passes through the kidneys, it filters the nitrogenous waste to form urine. It maintains the homeostasis of the body. The three major steps for urine formation include glomerular filtration, tubular reabsorption, and tubular secretion.
