Kidneys
(3 Parts)
- two structures located on each side of the lumbar region
- - filter blood, & secrete impurities, forming urine
- - 3 parts: cortex, hilum, medulla
-
Cortex
- outer part of the kidney
- - (cortex= bark)
-
Hilum
indented opening of the kidney where vessels enter & leave
-
Medulla
inner part of the kidney
-
Calyces
(Calices)
- system of ducts
- - (kalyx= cup of a flower)
-
Nephron
(3 Parts)
- microscopic functional units of the kidney
- - comprised of: kidney cells & capillaries (each capable of forming urine)
- - 3 parts: glomerulus, Bowman's capsule, renal tubule
-
Glomerulus
- little ball-shaped cluster of capillaries
- - located at the top of each nephron
-
Bowman's Capsule
top part of the nephron that encloses the glomerulus
-
Renal Tubule
stem portion of the nephron
-
Ureter
tube that carries urine from the kidneys to the bladder
-
Renal Pelvis
basin-like portion of the ureter within the kidney
-
Ureteropelvic Junction
point of connection between the renal pelvis & ureter
-
Urethral Meatus
opening in the urethra to the outside of the body
-
Urea
- waste product formed in the liver- filtered out of the blood by the kidneys
- - excreted in the urine
-
Creatinine
