Term
| Predict the effects that renal failure might have on the body's homeostasis |
|
Definition
1. The kidney serves as filter of the blood by removing wastes from the blood by producing urine and also reabsorb other important substances such as glucose.
renal failure: blood would come toxic as nitrogen and ammonium build up in blood.
2.Regulation of electrolytes, acid–base balance, and regulation blood pressure and volume. Kidney produces many hormones such as:
EPO (increase RBC production
Renin & angiotensin 1& 2 & ADH : to increase Blood vol and/or pressure
Renal failure: salt and water levels couldn’t be regulated therefore pressure and blood vol couldn’t be controlled . |

Term
| how is the pattern of blood flow unique in the kidney? How does this blood flow allow the kidney's form to follow its function? |
|
Definition
In the kidney 2 capallaries beds suround the tubules of the nephron in order to provide them with oxygen,nutrients.
The 2 capillary beds also also take substances that have been reasbsorbed by the tubules (glucose etc) back INTO the blood.
= this allows the kidney to
filter blood & reclaim fluid and solutes |

Term
| why is the epithelium of the bladder stratified? (2) |
|
Definition
prevent leakage
allows stretching without damage |
|
|
Term
| how does the form of the epithethilal tissue of the renal tubules follow its fcn? |
|
Definition
its simple (not stratified) & microvilli
= increase surface area for absorption |
|

Term
number the order of the way filtrate travels:
minor calyx
proximal tubule
collecting duct
capsular space
nephron loop
papillary duct
distal tube |
|
Definition
1. capsular space (filtrate formed)
2. proximal tubule
3.nephron loop/ loop of Henle
4.distal tubule
5.collecting duct
6. papillary duct
7.minor calyx |

Term
At the junction between the ascending limb of the nephron loop and the distal tubule we find a grp of densely packed cells called ________.
These cells come into contact with a portion of the afferent arteriole that contain cells called ________.
Together, the 2 are called the _______. |
