What is the basic functional unit of the kidney called?

• A. Nephron
• B. Glomerulus
• C. Alveolus
• D. Renal pelvis

Answer: (A)

The fundamental functional unit of the kidney is called the nephron. Each nephron plays a crucial role in filtering blood, reabsorbing essential substances, and excreting waste products as urine. This intricate process involves various parts of the nephron, including the glomerulus, which is responsible for filtering blood, and the tubules, which handle reabsorption and secretion. While the glomerulus is important to the nephron's structure and function, it is not the entire functional unit; rather, it is a component of the nephron. The alveolus, on the other hand, refers to the tiny air sacs in the lungs and is unrelated to kidney function. The renal pelvis is the area where urine collects before being funneled into the ureter, but it is not responsible for the filtration and reabsorption processes that the nephron manages. Therefore, the correct answer highlights the nephron as the integral unit responsible for the kidney's primary functions.
