Introduction to The Urinary System

This text provides a brief introduction to physical characteristics of urine, gross anatomy of urine transport, gross anatomy of the kidney, microscopic anatomy of the kidney, physiology of urine formation, tubular reabsorption, regulation of renal blood flow, endocrine regulation of kidney function, regulation of fluid volume & composition, and the urinary system & homeostasis.
