(39 cards)
What are the body fluid compartments
transcellular, plasma, interstitial, intracellular
Describe the normal movement of potassium
moves out of the cell down conc grad
Describe the normal movement of sodium
moves into cell down conc grad
Name some cations
sodium, potassium
Name some anions
chloride
What does the movement of sodium underpin
depolarisation of neurons, muscle
What is the driving force for chloride movement
move into the cell
What helps determine blood pressure
volume of plasma
Describe the relationship between plasma volume and BP
if plasma volume increases, BP increases
What sets the volume of plasma
sodium content
What regulates sodium content
kidneys
Where does the kidney lie
between 12th thoracic and 3rd lumbar
Name some congenital abnormalities of the kidney
ectopic kidney, horseshoe kidney, renal agenesis
Which congenital kidney abnormality is incompatible with life
renal agenesis
What does ectopic kidney disease cause
damage, kidney stones
Describe horseshoe kidney disease
kidneys fuse across the midline
What can horseshoe kidney disease cause
renal stone formation
Why is the medulla a dark colour
rich blood supply
What is the hilus
part of the kidney where the ureter comes out
What is the calyx
fibrous - holds kidney components together
What is the functional unit of the kidney
nephron
What is the function of the nephron
regulate body fluid volume and composition
What parts of the nephron sit in the cortex
proximal tubule, distal tubule, bowmans capsule
What parts of the nephron sit in the medulla
loop of henle, collecting duct
