Urinary 13 Flashcards
kidney
one of the bean-shaped organs that remove wastes from the blood and help maintain fluid and electrolyte balance in the body

cup-like structure that drains into the renal pelvis
renal artery
one of two vessels that branch off the abdominal aorta and supply the kidney with blood; left renal artery and right renal artery

outer part of the kidney
renal medulla
inner part of the kidney
renal pelvis
a reservoir in each kidney that collects urine
renal vein
one of two blood vessels that drain the kidney and connect to the inferior vena cava; left renal vein and right renal vein
nephron
microscopic functional unit of kidney that forms urine; found in the cortex and medulla, it consists of a renal corpuscle and its associated tubule; each kidney contains about 1 million nephrons
renal corpuscle
structure composed of the glomerulus and the glomerular capsule
glomerulus
one of several capillary clusters at the entrance of each nephron that initiate the process of filtering of the blood

collecting duct
tubule that connects the nephrons to the renal pelvis
distal convoluted tubule (DCT)
segment of the nephron between the nephron loop and the collecting duct
