Q

gas in alveoli o2 and co2

A

o2 100

co2 40

17
Q

oxygenated blood o2 and co2

A

o2 100

co2 40

18
Q

co2 in the blood

A

bicarbonate ions, carbonic acid, carbonate ions, dissolved and bound to haemoglobin

19
Q

haldane effect

A

o2 bound for haemoglobin reduces its affinity for co2

20
Q

reverse haldane effect

A

as o2 goes into tissues it increases its affinity for co2 from cells

21
Q

left shift

A

high affinity to oxygen, wont give oxygen to tissues

22
Q

right shift

A

lower affinity to oxygen, dumps oxygen

23
Q

left shift causes

A

alkaline, carbon monoxide binding

24
Q

right shift causes

A

high temp, acidic, raised pCO2, 2.3 DPG

25
Q

peripheral chemoreceptors

A

carotid body and aortic body

lop pH and high pCO2

26
Q

central chemoreceptors

A

brainstem, responds to extracellular fluid and pH
