Which are the two main parts of a nephron?

The two main parts of a nephron are indeed the renal corpuscle and the renal tubule. The renal corpuscle serves as the initial filtering component of the nephron, comprising the glomerulus and Bowman's capsule. This structure is critical for the filtration of blood, where water, electrolytes, and waste products are separated from blood plasma.

The renal tubule follows the renal corpuscle, where further processing of the filtrate occurs. This part is responsible for reabsorption of essential substances such as glucose, water, and ions back into the blood, as well as the secretion of additional waste products into the urine.

Together, these two components—the renal corpuscle and renal tubule—play crucial roles in urine formation and the overall function of the kidney in regulating fluid and electrolyte balance in the body. Understanding these parts helps clarify how kidneys filter blood and produce urine, which is vital for maintaining homeostasis.
