Chapter 27 Flashcards
Urology and Male Reproduction
what is pyelonephritis?
a urinary tract infection (UTI) of one or both kidneys. Prompt treatment is required to prevent kidney damage and septicemia
what is the term for excessive nitrogen compounds in the urine?
azoturia
what is hematuria?
blood in the urine
what is glycosuria?
glycose(sugar) in the urine
what brings blood into the glomerulus?
the afferent arterioles
what takes blood away from the glomerulus?
the efferent arterioles
what condition causes benign enlargement of the prostate gland in older men?
Benign Prostatic Hyperplasia (BPH)
what blood test is used to screen for prostate cancer?
Prostate-specific antigen blood test
what is the term for excessive urination?
polyuria
what is BUN, and what does it stand for?
Blood Urea Nitrogen; if kidney function is abnormal, the blood level of urea will be increased
what is VCUG?
voiding cystourethrogram: a minimally invasive test that involves flouroscopy to visualize the urinary tract and bladder
what is the term for pus in the urine?
pyuria
what is the term for the sudden uncontrolled need to urinate?
urgency
what is Escherichia Coli, and what does it cause?
a bacteria that is responsible for most UTI’s
with normal kidney function, what does not pass through the capillary walls and remains in the capillary?
white blood cells(WBC), red blood cells(RBC), and plasma proteins
what is filtration?
the first step in urine formation. A continual process that involves the renal corpuscle. Blood is brought to the kidneys by renal arteries, then the renal vein, and out of the kidney. Pressure is high in the glomerulus and this forces water and dissolved substances through the one-celled wall of the capillaries. The wall filters out the electrolytes, waste products, amino acids and glucose.
what is reabsorption?
substances move from the filtrate back into the blood into the peritubular capillaries. Reabsorption starts as filtrate moves out of the Bowman capsule and into the proximal tubule. When the filtrate moves into the Henle loop, the chloride and sodium ions move out of the filtrate and into the interstitial fluid and blood. Water, chloride, and sodium are reabsorbed into the blood as the filtrate passes through the distal tubule. The kidneys retain what is need to maintain homeostasis
what is secretion?
substances move from the blood to the filtrate. Urea moves back to the filtrate in the Henle loop. Ammonia, certain drugs, hydrogen, and potassium move from the blood to the filtrate. After the filtrate/urine leaves the collecting ducts the urine flows to the calyces and ureter before going through the rest of the urinary system
