patho

Question 1

acid base balance

Answer 1

pH level within normal 7.35-7.45
metabolic- pHCO3
respiratory - pCO2

Question 2

pHCO3

Answer 2

kidneys

Question 3

pCO2

Answer 3

lungs

Question 4

acidosis

Answer 4

low pH and either
drop pHCO3- metabolic OR
rise in pCO2 - respiratory

Question 5

alkalosis

Answer 5

high pH
rise pHC03- metabolic OR
drop in pCO2- respiratory

Question 6

aldosterone

Answer 6

secreted by adrenal cortex (due to NA changes)

signals the nephrons in kidneys to reabsorb NA and thus water- increase osmolarity and control K levels

Question 7

NA goes

Answer 7

water goes

Question 8

Renin

Answer 8

secreted in kidneys d/t NA or fld volume
acts on angiotensinogen (plasma protein) conveting to angiotensin I which gets converted to angiotensin II (leads to vascular constriciton and aldosterone secretion

Question 9

ADH

Answer 9

antidiuretic hormone- produced in brain, stored in pituitary and released with change in osmolarity of blood
acts on tubules in kidneys (leading to more water absorption and decrease osm)
Osm too low- ADH stop and water excreted in urine

Question 10

BNp

Answer 10

brain natriuretic peptide
produced with increase in BV and BP
then NA resabsoprtion is inhibited and GFR increased
blood osm is decreased, urine output increased
