3 Gross Anatomy of System Pair of kidneys Pair of ureters Urinary bladder Urethra Skin

4 Functions of Excretory System Regulate body fluids –Volume, pH, composition Remove metabolic wastes from blood Control rate of RBC formation Regulate blood pressure Regulate absorption of calcium

6 Gross Anatomy

7 The Kidney Kidney - Filters water and all solutes except proteins from blood; reclaims water and solutes as the body requires. Excretes the remainder, as urine.

8 The Blood Supply to the Kidney

9 Nephron Collecting duct DCT PCT Ascending tubule Descending Tubule Bowman’s capsule Glomerulus Vasa recti

10 10 Purpose of Nephron Millions of nephrons located inside of each kidneys Responsible for filtration and purification of blood Creates urine

11 11

12 12 Ureter - Channel for urine to flow from kidney to urinary bladder

13 13 Urinary Bladder - Stretchable container for temporarily storing urine

14 14 Urethra - Channel for urine to flow from the urinary bladder to the body surface
