ANATOMY OF THE HUMAN EYE: STRUCTURAL ORGANIZATION AND FUNCTIONAL ADAPTATIONS

Abstract
The human kidney is a paired excretory organ essential for maintaining fluid balance, electrolyte homeostasis, and the elimination of metabolic waste. Each kidney demonstrates a highly specialized anatomical structure that supports its role in filtration, secretion, and reabsorption. This article reviews the gross and microscopic anatomy of the kidney, its vascular supply, and its functional correlations. Emphasis is placed on the clinical importance of renal anatomy for surgery, nephrology, and transplantation.
Keywords
