|
|
Term
|
Definition
| the solution is more concentrated than blood |
|
|
Term
|
Definition
| urea leaks out at lower portion, creating a higher concentration in the inner medulla. |

Definition
|
|
Term
| define isotonic, and where is the fluid isotonic in nephron? |
|
Definition
| isotonic = same concentration as outside, DCT. |
|
|
Term
| what is hypertonic, and where in the nephron is the fluid hypertonic |
|
Definition
| more concentration outside than inside, descending limb, CD. |
|
|
Term
| what is tubular excretion, what is it similar to? |
|
Definition
substances are added to the tubular fluids from blood, actively. in the DCT
pressure filtration is better. |
|
|
Term
| what is the function of the kidney? |
|
Definition
| regulate pH, salt balance and volume of blood. |
|
|
Term
| how does the kidney maintain pH balance? |
|
Definition
when pH is acidic, it excretes more H+ in the form of NH3 (ammonia)
reabsorbs Na+ and HCO3, sodium and bicarbonate, forming a base NaHCO3 |
|
|
Term
|
Definition
| increase permeability of CD. so more water can be reabsorbed |

Term
| what is aldosterone? and where does it act on? |
|
Definition
| aldosterone causes reabsorption of Na+ and excretes K+ in DCT! |
|
|
Term
| what is renin, and where is it secreted by? what is renin converted to? and what is the effect of the converted enzyme? |
|
Definition
renin is to increase blood pressre, secreted by the afferent arteriole cell.
it changes to angiotension(angie) which stimulates adrenal cortex to release aldosterone. |
