Studied by 2 peopleglomerulus
small network of capillaries encased in the upper end of a nephron; where the filtration of blood takes place
Hilum
entrance to renal sinus which blood vessels, nerves, lymphatic vessels, and the ureter pass through
urethra
tube that conveys urine outside the body
urinary bladder
serves as a urine reservoir
detrusor muscle
interlaced muscle which forms the bladder wall
Trigone
triangular internal floor of the bladder which has an opening at each of the 3 corners
Bowman's capsule
cup-shaped structure of the nephron of a kidney which encloses the glomerulus and which filtration takes place
afferent arteriole
the small artery that carries blood toward the capillaries of the glomerulus
efferent arteriole
the small artery that carries blood away from the capillaries of the glomerulus
ureters
The tubes that carry urine from the kidneys to the bladder.
urine
substance secreted from body; made up of 95% water, urea, uric acid, & trace amounts of amino acids & electrolytes
Glomerular Filtration
1st step of urine formation which contains water & various substances dissolving and filtered out of blood between Glomerulus & Bowman’s Capsule
Filtration Pressure
net pressure acting to force substances out of the glomerulus
Ureter

Renal cortex
What region of the kidney is mainly composed of blood capillaries?
Bowman’s capsule
What part of the nephron that is most closely related to the glomerulus?
Urethra
What structure carries urine from the bladder to the outside of the body?
Metanephridium
Which structure is not part of the urinary system?
