Chapter 14 The Urinary System H&A Flashcards
(36 cards)
Normal variant that occurs on the left kidney as a bulge on the lateral border
Dromedary hump
Located outside of the normal position, most often in the pelvic cavity
Ectopic kidney
Stone within the urinary system
Urolithiasis
First layer adjacent t the kidney that forms a tough, fibrous covering
Renal capsule
Bands of cortical tissue that separate the renal pyramids; may mimic a renal mass on ultrasound
Columns of Bertin
Dilation of the renal collecting system
Hydronephrosis
Congenital malformation in which both kidneys are joined together by an isthmus, most commonly at the lower poles
Horseshoe kidney
Interruption in the normal development of the kidney resulting in absence of the kidney; may be unilateral or bilateral
Renal agenesis
Portion of a renal tubule lying between the proximal and distal convoluted portions; reabsorption of fluid, sodium, and chloride occurs here and in the proximal convoluted tubule
Loop of Henle
One of several conical masses of tissue that form the kikney medulla; each consists of the loops of Henle and the collection tubules of the nephrons
Renal pyramid
Retroperitoneal structures that exit the kidney to carry urine to the urinary bladder
Ureters
Inner portion of the renal parenchyma that contains the loop of Henle
Medulla
Small vessels found at the base of the renal pyramids; appear as echogenic structures
Arcuate arteries
Muscular retroperitoneal organ that serves as a reservoir for urine
Bladder
Part of the collecting system adjacent to the pyramid that collects urine and is connected to the major calyx
Calyx
Network of capillaries that are part of the filtration process in the kidney
Glomerulus
Central area of the kidney that includes the calyces, renal pelvis, renal vessels, fat nerves, and lymphatic
Renal sinus
Right posterior subhepatic space located anterior to the kidney and inferior to the liver where fluid may accumulate
Morison’s pouch
Small vessel that carries blood from the glomerulus of the nephron and conducts blood to the peritubular capillaries that surround the renal tubule
Efferent arteriole
Area in the midportion of the kidney where the renal vessels and ureter enter and exit
Renal hilum
Lab measurement of the amount of nitrogenous waste and creatinine in the blood
BUN
A product of metabolism; lab test that measures the ability of the kidney to get rid of waste
Creatinine
Maintenance of normal body physiology
Homeostasis
Lab tests that measure how much dissolved material is present in the urine
Specific gravity
