7-Gaseous Exchange Flashcards
formula of carbonic acid
H2CO3
formula of oxyhaemoglobin
HbO8
formula of haemoglobinic acid
HHb
CO2 transported by the blood is carried as
hydrogencarbonate ions, HCO3-
when oxyhae. react with hydrogen then release oxygen, it will becomes
haemoglobinic acid,HHb
5% of co2 simply dissolve in
blood plasma
10 of co2 is carried as
carbaminohaemoglobin
myoglobin found in
muscle cells
bohr effect ensures
excess co2 or h+ are removed
peripheral chemoreceptors found in
aortic and carotid bodies
peripheral chemoreceptors
responsible for immediate stimulation of breathing
central chemoreceptors responsible for
sustained increase in breathing rate until pH is normal
inspiratory centre found at
ventral part of breathing centre
expiratory centre found at
dorsal and lateral parts of the breathing centre
