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 kidney in a human contains about a million nephrons. These nephrons make the actual changes to the blood composition.There are two types of nephron: cortical nephron and juxtamedullary nephron. The main difference in the two types of nephron is the length to which the loop of Henle extends into the kidney.Cortical nephron, which are about eighty percent of the nephron in humans, have a loop of Henle that does not extend past the cortex of the kidney.ach kidney in a human contains about a million nephrons. These nephrons make the actual changes to the blood composition.
