Stack #39719

A&P2 Test 5 #7 Urinary-Physiology of Nephron

QuestionAnswer
Glomerular filtration involves a: relationshop bet endothelial pore size & size of available solutes
Endothelial pores restrict size of: materials that can pass thru the membrane into the capsule
Endothelial-capsular membrane seperating the blood: from space in the GC is very thin (0.1um)
Basement membrane permits passage of: smaller molecules & restricts flow of larger ones
filtration slits are located bet the: pedicels of the podocytes and are only 6-9nm wide
The efferent arteriole is much: smaller than afferent, so resistance to outflow is created
Consequently, the BP is higher in the: GC than in other capillaries (60mmHg vs 30mmHg elsewhere)
Hydrostatic pressure (BP) in the glomerulus: tends to move fluid out of the glomeruli
Capsular hydrostatic pressure opposes: filterate movement & some filtrate is pushed back into the capillary.
This occurs cause when filterate is forced: out of glomerular capillaries into space bet walls of GC it meets w/2 forms of resistance
Two forms of resistance: 1.walls of capsule &2. fluid that has already filled the renal tubule.
As a result of the resistance: some filtrate is pushed back into the capillary
Regulation of glomerular filteration involves: renal autoregulation & extrinsic controls
Ptosis is the dropping of kidney due to: loss of fatty tissue support. It is a bid prob if.when ureter gets kinked
Hydronephrosis kinked ureter causes urine to back up into kidney; it can lead to necrosis
Pylonephritis infection of renal pelvis & calyces.Can lead to infection of entire kidney
Anuria adnormally low urinary output per day (less than 50ml/day)
Reanl Calculi kidney stones; Most under 5mm in diam. Can have LITHOTRIPST vs surgery to remove
Urethritis inflammation of urethra
Cystitis bladder inflammation
Incontinence inability to control micturition
Diabetes insipidus injury or tumor in hypothalamus or posterior pituitary results in the under prod of ADH & over prod of urine
large molecules do not normally pass thru endothelial-capsular membrane
FILTERATION SLITS aka filteration pits or slit pores
FILTERATE is the product of filteration
UROCHROME is a: pigment by-product of the metabolism of bile
