GFR |
______ is the volume (mL) of filtrate produced over a period of time. |
|
|
Auto regulation |
If BP drops slightly and NFP drops then the afferent arteriole dilates to increase blood flow into the glomerulus, keeping pressure and filtration rates close to normal. |
|
|
Autonomic regulation |
Sympathetic stimulation constricts the afferent arteriole, decreasing GFR. Less urine is produced |
|
|
Hormonal regulation |
If the BO drops noticeably then the juxtaglomerular cells release renin. This initiates the renin-antiogenisin pathway to increase aldosterone levels. JG cells release EPO to increase RBC production. Increase in BV and BP |
|
|
Cotransport |
2 or more substances are transported in the same direction |
|
|
Counter transport |
2 or more substances are transported in opposite direction |
|
|
Facilitated diffusion |
Passive movement of a substance that requires the presence of another substance in order to occur |
|
|
Active transport |
This is driven by the hydrolysis of ATP to ADP on the inner plasma membrane surface. |
|
|
Tubular maximum |
_______ ______ is the plasma concentration of a substance at which 100% of hat substance will be reabsorbed. |
|
|
Renal threshold |
_______ ______ is the plasma concentration at which a substance begins to appear in urine |
