Document Summary

Nephron makes up most of the kidney lobe. Blood vessels delivered to cortex (renal corpuscle, blood meets nephron, where blood is filtered: a medullary pyramid and all of the cortex that surrounds it comprises a kidney lobe. Makes up bulk of kidney (1 million nephrons per kidney); very important! Filter the blood and produces the urine; urine formation is main function; excrete the urine away from body. Types of nephrons (2 types; names based on location): cortical nephrons. Renal corpuscle of this nephron is in the cortex (so are its pct and dct: juxtamedullary nephrons (sit next to start of medulla) What"s different: loop of henle itself extends deep down into the medullary tissue. Bowman"s capsule (wrap around outside of glomerulus to form renal corpuscle) Renal tubules pct, loop of henle, dct and cd) Peritubular capillaries wrap around tubules; glomerular capillaries form the glomerulus.
