ADH
collecting duct

Question 11

Renin

Answer 11

released by juxtaglomerular cells to increase volume/ bp

Question 12

ANP and BNP

Answer 12

the heart has too much volume so it releases these hormones to increase filtration and secretion of H20 and Na

acute cystitis

Question 26

Acute glomerularnephritis

Answer 31

glomerular inflammation due to infection there are two types due to immune problems or nonimune

Question 32

-Type III hypersensitivity to antibodies -Happens because of streptococci seen in strep or impetigo -causes hypertension, hematuria, periorbital edema, proteinuria treatment- corticosteroids, antibiotics, dietary restrictions

Answer 32

Immune version of acute glomerularnephritis

Question 33

Nephrotic syndrome

Answer 33

- this is massive proteinuria (proteins in pee) surpassing the normal level of 3.5g -causes hypoproteinema in blood -treatment : diet

Question 34

In ___ syndrome, since theres no proteins in blood, liver overproduces ____ which leads to ____.

Answer 34

-nephrotic -lipoproteins -hyperlipidemia

Question 35

-This syndrome consists of proteinuria and hematuria -causes acute renal failure and there are three types

Answer 35

-Nephritic syndrome 1. pre renal 2.intrarenal 3.postrenal

Question 36

Intrarenal

Answer 36

caused by acute tubular necrosis and glomerulonephritis -treatment- focus on the underlying cause, dialysis,diet -one should monitor the blood work

Question 37

Prerenal

Answer 37

-this can be reversed -less than 25% perfusion -happens due to dehydration

Question 38

What are the three stages of infrarenal manifestations?

Answer 38

1. initiation phase 2. oliguric phase:less urine, hypertension, high BUN,Cr,K &P, and low Na and Ca 3. polyuric phase: recovering, peeing more

hypotension, nephrotic drugs (NSAIDS), aminoglycosides
