The basic filtration unit in the kidneys is the nephron. Each kidney contains approximately 1 million nephrons. The nephron consists of a renal corpuscle and a renal tubule. The renal corpuscle comprises the Bowman’s capsule and glomerulus, where blood is filtered. Blood enters the glomerulus, and the Bowman’s capsule collects the filtrate. The renal tubule then processes the filtrate through three segments: the proximal convoluted tubule, the loop of Henle, and the distal convoluted tubule. Throughout these processes, essential substances are reabsorbed, and waste products form urine. Nephrons play a crucial role in maintaining fluid and electrolyte balance in the body.
