Urinary Systems and Electrolytes III
Cards in this deck (20)
- 1Components + function of urinary system (4)Kidneys = urine production = excretion and regulation
Ureters = urine transfer to bladder
Bladder = urine storage = elimination
Urethra = urine release = elimination - 2What are the adrenal glands comprised of and what hormones do they release?Cortex and medulla
Corticosteroids + Aldosterone
Adrenaline + Noradrenaline - 3What are their functions?Cortex - Na+/H2O retention, increase BP and volume
Medulla - fight or flight response - 4What is the location of the kidneys?T12-L3, retroperitoneal
- 5Why is the right kidney inferior?Liver
- 6Draw a diagram of a transverse cut of kidneysAnt.
Post.
Rich blood supply necessitates heavy protection. - 7What is the function of the renal capsule?Protect + regulates size of kidney
- 8What surrounds the R. capsule?Layers of perinephric fat
R. Fascia - 9What are the R. fascia?Collagenous suspensory fibres
- 10Draw a diagram of a kidney (8)Renal lobe
Renal pyramids
Minor calyx
Medulla
Major calyx
R. pelvis
Cortex
R. column - 11How do these compartments relate? (5)Cortex sends projections to R. Columns
Divides kidney into R. Pyramids
Which collectively form R. Medulla
Cortex + Pyra = R. lobe
Location of nephron the functional unit of the kidney - 12Nephron diagram (14)Glomerulus

Peritubular cavity
Interlobular vein
Cortex
Medulla
CD
Pelvis - 13Nephron functioning (6)CD spans length of lobe from out cort -> medulla
Emerges at R. papillae
Urine passed to minor calyx around R. pap
Collect into major calyx
Pass through R. pelvis
Located in R. sinus - 14Renal circulation (5)interlobular artery
arcuate artery
segmental artery
renal artery
renal vein - 15Ureters (3)Retroperitoneal throughout length
Compression close off ureters like one-way valve
Prevents backflow - 16Bladder surfacessuperior
inferolateral x2
^^ meet at apex
posterior - 17What is the triangle of the bladder?Between ureters and urethra
Smooth trigone surface funnels urine down to urethra
Rest is thrown into rugae - 18What are the muscular walls of bladder formed by?Detrouser muscle
- 19Men vs. Women urethraMen - s shaped 4 curves
women - share pelvic cavity - 20What do external urethral sphincters do?External prevent reflex of semen into bladder
