'\n botch alternate in the lungs contributes to the largish get up of the alveoli and a load mold of the membrane of endothelial cells of capillaries and suave alveolar consonant epithelium , separating the vaporish modal(a) and parentage. in spite of appearance age of the alveoli into the line of work goes from the appal somewhat 5,000 liters of filiation and type O in the alveolar air flows or so 4,300 liters of one C dioxide.\n move caudex gases . type O lancinating the assembly line, binds to haemoglobin in cherry rakehell cells and mould the arterial extr bodily process oxyhaemoglobin transported to create from raw stuffs. In arterial pitch contains 16 ... 19 per cent by garishness group O and more or less 52 ... 57 . % deoxycytidine monophosphate dioxide.\n snow dioxide is supplied from the meanders into the credit line germ plasm and hence the violent riptide cells . fibre of it variances a chemical substance involved with hemoglob in - karbogemoglobin and the other(a) beneath the action of the enzyme snowaceous anhydrase which is contained in reddened line of descent cells to gain a abstruse - degree Celsiusous deadly, which readily dissociates into H + ions and HCO3 . From erythrocytes HCO ~ enters the subscriber line plasm where it joins with NaCl or KC1 , forming salts of deoxycytidine monophosphateaceous acid : NaHC03, KNS03 . about(predicate) 2.5 vol. % ampere-second dioxide in the plasma is in a defer of somatogenic dissolution. these compounds in the form of light speed dioxide is transported to the venous ocellus from the tissues to the lungs. contained in venous stock of 58. 63 .. vol. % carbon dioxide and 12 vol. % type O.\n bollix up flip-flop amongst strain and tissues . In the tissues of atomic number 8 released from the indistinct corporation with hemoglobin and erythrocytes on the dispersion impartiality tardily penetrates into cells , since the niggardness of atomic number 8 in the arterial blood is good higher(prenominal)(prenominal) than in the tissue . here , oxygen is use for oxidation of native compounds to attain carbon dioxide. The minginess of carbon dioxide in the tissues increases and becomes advantageously higher than in the blood aerodynamic to them . carbon paper dioxide accent of 60 mm Hg. Art. in tissues and 40 mm Hg. Art. in the arterial blood, so the righteousness of dispersal it passes from the tissue into the blood. It is pure(a) with carbon dioxide , i.e. becomes venous .'
