1 Urinary System and Body Fluids By Deon Thomas and Micah Simmons

2 Summary The urinary system rids the body of waste materials, regulates fluid volume, maintains electrolytes concentrations in body fluids, and control blood pH.

3 Vocabulary  Anuria (an-YOU-rih-ah)  Condition in which there is no formation of urine  Azotemia (Az-oh-TEE-mee-ah)  Presence of increased amounts of nitrogen waste products in the blood.  Blood Urea Nitrogen (BUN)  A blood test to determine the amount of urea that is exported by the kidneys  Dialysis  A procedure to separate waste material from the blood and to maintain fluid, electrolyte, and acid base balance when kidney function is impaired.  Nephritis (nef-RYE-tis)  Inflammation of the kidney

4 Vocabulary (continues)  Diuresis (dye-you-REE-sis)  A condition of increased or excessive flow of urine.  Diuretic (dye-you-RET-ik)  A substance that increases the production of urine  Enuresis (en-you-re-sis)  Involuntary emission of urine; wetting the bed  Nephrectomy (nef-Rek-toh-mee)  Surgical removal of a kidney  Nocturia (nahk-TOU-rih-ah)  Excessive urination at night

5 Components of the Urinary System  The urinary system consists of the kidney, urinary bladder, urethra, and a few more parts.  The primary organs of the urinary system are the kidneys, which are located between the 12 th thoracic and 3 rd lumbar vertebrae.

6 Each Component  Urinary Bladder  The Urinary bladder is a temporary storage reservoir for urine.  Urethra  The final passageway for the flow of urine is the urethra, a thin-walled tube that conveys urine from the floor of the urinary bladder to the outside.

7 Blood flow through the kidney  Blood flow through the kidney goes in the sequence of renal artery  Segmental artery  interlobar artery  arcuate artery  afferent arteriole  glomerulus  efferent arteriole  Interoblular vein  arcuate vein  interlobar vein  segmental vein  renal vein  inferior vena cava.

8 Body fluids  Fluids make up 60% of an adults weight.  Two thirds of the fluids are intracellular  One third of the fluids are extracellular

9 Intake and Output of Fluid  Intake:  Sources of fluids intake are beverages, food, and metabolic water.  Output:  Fluids loss are through the kidneys, skin, lungs, and gastrointestinal tract.

10 Alkalosis  Definition: Condition in which the blood has a higher pH than normal.  pH above 7.45  How it happens: Cellular metabolism produces substances that tend to upset the pH balanced.

11 Urinalysis  The volume, physical characteristics, and chemical composition of urine changes with diet, physical activity, and state of health. A chemical and microscopic examination of urine, are called urinalysis.
