Detailed explanation-1: -A nephron is the basic structural and functional unit of the kidney. They are the microscopic structure composed of a renal corpuscle and a renal tubule . The word nephron is derived from the Greek word – nephros, meaning kidney. There are about millions of nephrons in each human kidney.

Detailed explanation-2: -Each of your kidneys is made up of about a million filtering units called nephrons. Each nephron includes a filter, called the glomerulus, and a tubule. The nephrons work through a two-step process: the glomerulus filters your blood, and the tubule returns needed substances to your blood and removes wastes.

Detailed explanation-3: -The nephrons are called uriniferous tubules as they are the site of urine formation.

Detailed explanation-4: -human kidney Each nephron is a long tubule (or extremely fine tube) that is closed, expanded, and folded into a double-walled cuplike structure at one end. This structure, called the renal corpuscular capsule, or Bowman’s capsule, encloses a cluster of capillaries (microscopic blood vessels) called the glomerulus.

Detailed explanation-5: -Listen to pronunciation. (REE-nul kuh-LEK-ting TOO-byool) The last part of a long, twisting tube that collects urine from the nephrons (cellular structures in the kidney that filter blood and form urine) and moves it into the renal pelvis and ureters. Also called collecting duct.
