What is a nephron?
The nephron is the functional unit of the kidney, consisting of a filtration apparatus otherwise known as the glomerulus (“bag of worms”) at one end, with a U-shaped hair-pin loop called the “loop of Henle” in the mid-portion (which helps alter the composition and concentration of the urine as it is being formed), and terminating at the urine collecting duct, before tracking its way out of the body. As blood filters into the nephron to make its way to the outside, the minor miracle of water transmutating into urine is effected.
