1
Q

major organs

A

kidneys, ureters, bladder, urethra

2
Q

functions of urinary system

A

primary function - filter blood

3
Q

functions of urinary system involving filtrate

A

elimination of metabolic waste
regulation of ion levels
regulation of acid-base balance
regulation of BP e
elimination of biologically active molecules
other functions: calcitrol formation, production and release of EPO (increases RBCs when O2 levels are low), potential to engage in glucogenesis

4
Q

Parts of a nephron

  • renal corpuscle
  • glomerulus
  • glomerulus capsule
  • renal tubule
A

filtration in the nephrons
network of blood vessels (fenestrated capillaries)
cup-shaped structure
made up of PCT, descending limb, ascending limb. DCT and collecting duct

5
Q

What is a nephron? what are the two types of nephrons?

A

a functional unit of the kidneys
juxtamedullary - longer loop
cortical - shorter loop

6
Q

Renal blood flow pathway

A

renal artery, segmental arteries, interlobar arteries, arcuate arteries, cortical radiate arteries, afferent arteriole, glomerulus, efferent arteriole, pertitubular caps. and vasa recta, cortical radiate veins, arcuate veins, interlobar veins, renal vein

7
Q

filtrate flow

A

glomerular capsule, PCT, descending limb, ascending limb, DCT, collecting duct, papillary duct, minor calyx, major calyx, renal pelvis,/sinus, ureter, bladder, urethra

8
Q

List the 3 processes in urine formation

A
  1. glomerular filtration - renal corpuscle filtering substances out of blood into nephron/capsule
  2. tubular reabsorption
