Nephron, functional unit of the kidney, the structure that actually produces urine in the process of removing waste and excess substances from the blood. There are about 1,000,000 nephrons in each human kidney. The most primitive nephrons are found in the kidneys (pronephros) of primitive fish, amphibian larvae, and embryos of more advanced vertebrates.
Each of our kidneys contains over a million nephrons. They are the functioning unit of the kidneys. They remove waste from the body and produces urine. Each nephron is made up of two parts: a renal corpuscle and renal tubules (Figure 1). Figure 1. Schematic diagram of the nephron demonstrating the site of action of diuretics.
