2 Unit 10 Anatomy/Physiology

3  Kidneys filter out all the waste in the blood stream  Broken down red blood cells and bile both contain “urochrome” which has a yellow color! (otherwise all pee would be clear)  Did you know…  In the 1600’s, alchemists believed our pee to contain gold b/c it was yellow. Many actually tried to extract gold from pee….yuk!

5 The three main causes of abnormal urine color are: -Foods -Medications/drugs -Health issues Red or pink urine may be caused by: Blood – UTI’s, enlarged prostate, tumors, kidney cysts, long-distance running, and stones Foods - Beets, blackberries and rhubarb can turn urine red or pink. Medications You can blame orange urine on: Medications Medical conditions Dehydration Blue or green urine can result from: Dyes – Foods and kidney or bladder test dyes Medications Medical conditions - Familial hypercalcemia (blue diaper syndrome ) and UTI’s caused by pseudomonas Dark brown or tea-colored urine Food – Fava beans, rhubarb or aloe Medications. Medical conditions - Liver and kidney disorders and UTI’s Cloudy or murky urine Urinary tract infections and kidney stones

6  About 150 liters (33 gallons) of fluid pass through your kidneys every day. But 99% of this cleaned and goes back into your blood. Leaving 2 liters for your urine!  People pass about 40,000 liters (8,800 gallons) of urine in their lifetime. This is enough to fill 500 bath tubs!!!

8 1) Filters dissolved material from the blood 2) Regulates electrolytes* 3) Regulates blood volume 4) Reabsorbs important substances back into the circulatory system * free ions in solution that regulate pH, blood volume,blood pressure, muscle and brain functioning, ex. Include Na +, K +, Mg +, Ca ++

9  Kidney: sits in the lower back, embedded in tissue and fat for protection  Bean shaped, x2 1. Renal Veins/Arteries: supplies blood flow to and from the kidney 2. Renal Capsule: tough connective tissue that coats the kidney

10

11 3. Hilus: depression where the arteries, veins, and ureters enter/exit 4. Cortex: outer layer, loaded with nephrons and blood vessels 5. Medulla: area containing collecting ducts and blood vessels (inner layer)

12 Inferior Vena Cava Abdominal Aorta

13 Hilus

14  Ureter: long, thin tubes that conduct urine from the kidneys to the bladder  Urinary Bladder: muscular holding chamber (elastic) for urine  Posterior to pubic bone  Ureters drip urine constantly into  “trigone” muscular region leads to urethra with sphincters

15  Terminal organ of urinary system  Has 2 sphincters for “control”  Approx. 20 cm in males, serves 2 functions and is routed through the prostate gland  Approx. 3-4 cm in females  Which gender usually gets more UTI’s?  WHY?

16  Where the urinary system and cardiovascular system meet  Functional unit of the kidney  Millions of them filtering blood in the cortex and emptying into the medulla  Materials being released and absorbed based on what the body needs second to second  What kinds of materials??

17 THE NEPHRON -Main function is water and salt balance, eliminate waste -Normal kidneys have 800,000-1.5 million! -Watch here how it works!here
