Chapter 6: Urinary System Flashcards
kidney
bean shaped organs located on each side of the vertebral column on the posterior wall of the abdominal cavity. function to remove waste products from blood and aid in maintaining water and electrolyte balance
nephron
urine producing microscopic structure. apprx. 1 million nephrons are in each kidney
glomerulus
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 in the kidney that collects urine and passes it to the ureter
hilum
indentation on the medial side of the kidney where the renal artery, vein, and pelvis are located and the ureter leaves the kidney
ureters
2 slender tubes, approx. 10 -13 inches long, that receive the urine from the kidneys and 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. the narrow tube varies in length by sex. in males it is also part of the repro. system and carries seminal fluid.
