Chapter Overview
The Human Urinary System is responsible for removing metabolic waste products from the body and maintaining a stable internal environment. It regulates water balance, salt concentration and the removal of harmful substances produced during metabolism.
The urinary system consists of two kidneys, two ureters, a urinary bladder and a urethra. Among these organs, the kidneys perform the most important function by filtering blood and producing urine. The nephron is the basic structural and functional unit of the kidney where filtration and urine formation occur.
This chapter explains the structure and functioning of kidneys, the process of urine formation and common urinary system disorders. Understanding these concepts helps students prepare for board examinations and learn how the body maintains homeostasis through excretion.
