|
4 steps of urine formation |
1.Glomerular filtration allows all diffusible materials to pass from the blood into the nephron 2.Tubular reabsorption moves useful substances back into the blood 3.Tubular secretion moves additional substances from the blood into the nephron 4.Concentration allows water to be reabsorbed from the nephron thereby decreasing the urine volume |
|
|
Urine is collected in the _______ it then travels to the _______ by way of two muscular tubes called ________ |
Renal pelvis, Bladder, Ureters |
|
|

|
|
Tube that leads from the bladder to the outside of the body is called the |
Urethra |
|
|
What causes a diabetic patients' urine to contain glucose |
The level of glucose in the blood exceeds the rate that it can be reabsorbed in the tubules |
|
|

water, distal collecting tubule |
|
|
Normal constituents of urine |
Urea, pigment, and sodium chloride |
|
|
Two main compartments of body fluids are |
intracellular fluids, and extracellular fluids |
|
|
The control center for thirst |
Hypothalamus |
|
|
Inflammation of the bladder, symptoms : urinary frequency, dysuria, bladder spasms, fever, hematuria cause : most common is E. Coli in GI tract |
Cystitis |
|
|
inflammation of the glomerular membrane of the nephron caused by build up of antigen - antibody complexes from strep infection |
Glomerulonephritis |
|
|
Uncontrollable loss of urine |
incontinence |
|
|
non-inflammatory disease in which the glomerular membranes allow a large number of protein molecules to leave the blood |
Nephrotic Syndrome |
|
|
Genetic disorder in which the renal tissue is replaced with grapelike clusters of fluid filled cysts |
Polycystic Kidney Disease |
|
|
inflammation of the renal pelvis caused by bacterial infection results in fever, urgency, dysuria, back pain, nocturia, hematuria, fatigue, lack of appetite, and chills |
Pylonephritis |
|
|
Kidney Stones |
Renal Calculi |
|
|
Sudden cessation of kidney function caused by obstruction, inadequate circulation, or damage to nephrons |
Acute Renal Failure |
|
|
End result of progressive loss of kidney function |
Chronic Renal Failure |
|
|
Narrowing of a passageway in the urinary tract usually involves ureter or urethra |
Stricture |
|
|
Waste products that are normally found in the urine are retained in the blood caused by kidney diseases |
Uremia |
|
|
Systems that eliminate waste (and what they eliminate) |
Urinary - Removes waste from blood Digestive - Eliminates water, solid wastes Respiratory - Eliminates water, CO2 Skin - Eliminates water, salts, nitrogenous waste |
