Capitolo 25, Problema 2
The basic functional unit of the kidney is the __________.
Guida verificata passo dopo passo1
Understand that the question asks for the basic functional unit of the kidney, which is the smallest structure capable of performing all kidney functions.
Recall that the kidney's main functions include filtering blood, reabsorbing needed substances, and secreting wastes into urine.
Identify that the nephron is the microscopic structure responsible for these processes, consisting of components like the renal corpuscle and tubules.
Recognize that other options such as the major calyx, loop of Henle, and glomerulus are parts of the kidney or nephron but not the entire functional unit.
Conclude that the nephron, which includes the renal corpuscle and tubules, is the correct answer as it performs the kidney's essential functions.
Concetti chiave
Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.
Nephron
The nephron is the basic functional and structural unit of the kidney responsible for filtering blood and forming urine. Each kidney contains about one million nephrons, which regulate water and soluble substances by filtering the blood, reabsorbing needed materials, and excreting waste.

Types of Nephrons
Renal Corpuscle
The renal corpuscle is the initial filtering component of the nephron, consisting of the glomerulus and Bowman's capsule. It filters blood plasma to form a filtrate that enters the nephron tubules for further processing.

Loop of Henle
The loop of Henle is a U-shaped segment of the nephron tubule that concentrates urine by reabsorbing water and salts. It plays a critical role in maintaining the body's water and salt balance through countercurrent exchange mechanisms.
