Summary Introduction

Introduction:

Urine is the fluid formed after the kidney filtrate has undergone tubular secretion and reabsorption. It is passed from the collecting duct to the papillary duct, from where it moves to the ureters. It generally contains water as well as potassium (K), chloride, and hydrogen ions (H⁺). It also contains metabolic wastes, such as urea, ammonia, creatinine as well as uric acid. The analysis of the components of urine is a valuable tool in the diagnosis of several health problems.
