exchange between oxygen and carbon dioxide which takes place in alveoli is called as
external respiration
internal respiration
cellular respiration
exchange between oxygen and carbon dioxide near with body tissue is called as
external respiration
internal respiration
cellular respiration
choose all correct statements about external respiration!
the process involving role of alveoli
O2 concentration in alveoli is higher than in RBC so O2 move to RBC
CO2 concentration in RBC is higher than in alveoli so CO2 move to alveoli
the gas exchange happen by passive transport
from alveoli, RBC rich with O2 are sent to heart, and received by left atrium
choose all correct statements about external respiration!
RBC rich of CO2 is coming from heart, transported by pulmonary artery, and later the CO2 diffuse to alveolar space
external respiration involves air in external environment
the gas exchange happen by active transport
from alveoli, RBC rich with O2 are sent to heart, and received by left atrium
these are the characteristics of alveoli which allow diffusion of gases happen efficiently. choose all that apply!
they have thin wall only consists of a single layer of cell
they are always moist
they are surrounded with web-like capillaries
their size is so small, giving an increase of total surface area
which one of this showing a combination between haemoglobin with the gas they bring while the RBC is oxygenated?
oxyhaemoglobin
carbaminohaemoglobin
carboxyhaemoglobin
haemoglobinic acid
which one of this showing a combination between haemoglobin with carbon dioxide?
oxyhaemoglobin
carbaminohaemoglobin
carboxyhaemoglobin
haemoglobinic acid
which one of this showing a combination between haemoglobin with the poisonous carbon monoxide?
oxyhaemoglobin
carbaminohaemoglobin
carboxyhaemoglobin
haemoglobinic acid
which one of this showing a combination between haemoglobin with the hydrogen ion?
oxyhaemoglobin
carbaminohaemoglobin
carboxyhaemoglobin
haemoglobinic acid

which one is the correct order of membranes that should be passed by an oxygen from alveolar space to RBC?
pneumatocyte cell membrane-capillary endothelial cell membrane-red blood cell membrane
capillary endothelial cell membrane-red blood cell membrane-pneumatocyte cell membrane
capillary endothelial cell membrane-pneumatocyte cell membrane-red blood cell membrane
red blood cell membrane-capillary endothelial cell membrane-pneumatocyte cell membrane
which one is the correct order of membranes that should be passed by a carbon dioxide from RBC to alveolar space?
pneumatocyte cell membrane-capillary endothelial cell membrane-red blood cell membrane
capillary endothelial cell membrane-red blood cell membrane-pneumatocyte cell membrane
capillary endothelial cell membrane-pneumatocyte cell membrane-red blood cell membrane
red blood cell membrane-capillary endothelial cell membrane-pneumatocyte cell membrane
these are the reactions that happen in internal respiration. choose all that apply!
CO2+H2O --> H2CO3
H2CO3 --> H+ + HCO3-
H+ + Hb --> HHb
HbO8 --> Hb + 4O2
near the tissue, .... CO2 present, it ... the pH of blood, and .... the affinity of Hb towards oxygen, oxygen released.

less, increases, decreases
less, decreases, increases
right after diffusing from tissue into red blood cell, CO2 ...
combine with water and by the help of carbonic anhydrase it turns to carbonic acid which then split into its ions
bind to haemoglobin to form carboxyhaemoglobin which then released to external environment
is chemically modified to be carboxyhaemoglobin, diffuse out from red blood cell, and transported in blood plasma
undergo several chemical reaction and the final products are bicarbonate ions and hydrogen ions which increase blood pH
Which of the following is NOT the form of CO2 while being transported around body?
carbonic acid
carbaminohaemoglobin
dissolved carbon dioxide
bicarbonate ion
