1
Q

blood pH below 7.35

A

acidosis

2
Q

blood pH above 7.45

A

alkalosis

3
Q

most acid comes from blank but second is from blank

A

metabolism, diet

4
Q

major components of body’s buffering system

A

CO2, HCO3-

5
Q

equilibrium toward H+ production

A

acidosis

6
Q

equilibrium toward H+ consumption

A

alkalosis

7
Q

metabolic pH imbalance is due to changes in blank

A

HCO3-

8
Q

respiratory pH imbalance is due to changes in blank

A

CO2

9
Q

increased CO2 leads to increased blank

A

H+

10
Q

plasma that is adequately ventilated will not have a build up of co2 because it is a blank system

A

open buffering

11
Q

lung regulates the blank balance of blood

A

co2

12
Q

kidneys control balance of blank

A

hco3

13
Q

bicarbonate is the only solute reabsorbed by PT that does not use blank cotransport

A

sodium

14
Q

blank happens at apical

A

H+ secretion

15
Q

blank happens at basolateral

A

HCO3- reabsorption

16
Q

how the kidney prevents from becoming less acidic than 4.4

A

binds H+ to non HCO3- buffers

17
Q

nonvolatile buffers

A

phosphate, creatinine, urate

18
Q

most commonly used nonvolatile buffer used to bind to H+

A

phosphate

19
Q

new hco3 can be derived from blank breadown

A

glutamine

20
Q

proximal tubule cannot maximally acidify urine so blank play an important supporting role via blank cells

A

distal tubule, intercalated

21
Q

alpha intercalated cells secrete blank

A

acid

22
Q

beta intercalated cells secrete blank

A

base

23
Q

hyperventilation leads to blank due to blank co2

A

respiratory alkalosis, decreased

24
Q

poor ventilation leads to blank due to blank co2

A

respiratory acidosis, increased

25
Q

proximal tubule acidosis causes blank and is due to decreased plasma bicarbonate due to mutations of blank

A

stunted height/weight, blindness, sodium bicarbonate cotransporter
