(A) The diffusion membrane is made up of three major layer squamous epithelium of alveoli, endothelium of alveolar capillaries and basement substance in between them.
(B) Total thickness of diffusion membrane is more than millimeter.
(C) Alveolar wall of alveoli is one celled thin wall.
(D) About 97% of O2 and 20-25 % of CO2 is transported by Hb in the blood.
(E) 3% of O2 and 7 % of CO2 is carried in a dissolved state through plasma of blood.
(F) O2 bind with Hb in reversible manner to form oxyhaemaglobin. Each Hb molecule can carry a maximum of two molecules of O2
(G) A sigmoid curve is obtained by plotting percentage saturation of Hb with O2 against pO2 . This curve is called oxygen dissociation curve.
(H) For the formation of oxyhaemoglobin in the alveoli, favourable factors are high pO2, low CO2 low pH and lower temperature.
(I) Every 100ml of oxygenated blood can deliver 5 ml of O2 to the tissue under normal physiological conditions.
(J) CO2 is carried by haemoglobin as carbamino - haemoglobin.
