  1. Urinary System Chapter 17

  2. Locate the Kidneys • On the back wall of the abdomen • Between the 12th thoracic and 3rd lumbar vertebrae • Are positioned retroperitoneally. • Behind the membrane that encloses the abdomen • Against the muscles of the back

  3. Describe the physical appearance of a kidney • Looks like a kidney bean! • Outer surface is convex, inner is concave. • Has two regions: • Medulla – inner region, looks striated • Cortex – outer region, appears granular

  4. Name the kidney’s functional unit • The nephron. • Tiny tubules that are inside the kidney. • Responsible for the filtration of blood and production of urine.

  5. Briefly describe the process that produces urine. • Glomular filtration • The process of filtration of the plasma by glomerular capillaries. • Tubular reabsorption • When the kidney reclaims the right amounts of substances: • Glucose, water, electrolytes • Tubular secretion • When some substances are eliminated more quickly • Hydrogen ions and toxins

  6. List the normal constituents of urine • 95% water – depending on hydration • Urea and uric acid • Amino acids • Electrolytes

  7. Identify a possible diagnosis from a urinalysis

  8. Describe the pathway/Why its possible • Kidneys • Ureters – 2 – come from each kidney and empty into the bladder • Bladder – muscular walls, can stretch • Urethra – 1 – has a sphincter that is consciously controlled – you tell it when to open.
