Bowman's Capsule Glomerulus is "ball" of blood capillaries embedded in "ball-like" end of Proximal Tubule; this Ball-like end is called Bowman's Capsule. Capillaries are surrounded by special cells called "Podocytes" which have specialized joinings which act as filters, excluding blood cells and proteins from entering the Proximal Tubule Proximal Tubule Active transport "OUT" of Na+. Na+ co-transport of glucose, amino acids, vitamins, etc. H 2 O out by osmosis (65% of entering). Toxin excretion.

Unformatted text preview: Loop of Henle Establishes Na+ concentration gradient which "extracts" H 2 O from urine (by osmosis) as it descends through this gradient in the collecting ducts. Distal Tubule Similar to Proximal Tubule. Hormonally regulated K+ secretion and H 2 O recovery. Collecting Duct "Descends" from cortex, through medulla, emptying into Renal Pelvis. "Descends" through increasing Na+ concentration H 2 O removed by Osmosis. Final urine is what drips out of collecting duct....
