kidneys | two bean-shaped organs located on each side of the vertebral column on the posterior wall of the abdominal cavity behind the parietal peritoneum. Their function is to remove waste products from the blood & to aid in maintaining water & electrolytes. |
nephron | urine-producing microscopic structure. Approximately 1 million nephrons are located in each kidney. |
glomerulus (pl. glomeruli) | cluster of capillaries at the entrance of the nephron. The process of filtering the blood, thereby forming urine, begins here. |
renal pelvis | funnel-shaped reservoir that collects the urine & passes it to the ureter |
hilum | indentation on the medial side of the kidney where the ureter leaves the kidney |
ureters | two slender tubes, approximately 10-13 inches (26-33 cm) long, that receive the urine from the kidneys & carry it to the posterior portion of the bladder |
urinary bladder | muscular, hollow organ that temporarily holds the urine. As it fills, the thick, muscular wall becomes thinner, and the organ increases in size. |
urethra | lowest part of the urinary tract, through which the urine passes from the urinary bladder to the outside of the body. This narrow tube varies in length by sex. It is approximately 1.5 inches/3.8 cm long in females & approximately 8 inches/20 cm in males. |

urinary tract infection (UTI) | infection of one or more organs of the urinary tract |
acute renal failure (ARF) | a sudden & severe reduction in renal function resulting in a collection of metabolic waste in the body. Prompt treatment can reverse the condition & recovery can occur. |
