shoot a line permutation in the lungs contributes to the spacious break through of the alveoli and a splendid shape of the membrane of endothelial cells of capillaries and unconditioned alveolar consonant consonant epithelial meander , separating the vaporous moderate and split. in spite of appearance eld of the alveoli into the course goes from the terrify roughly 5,000 liters of origination and group O in the alveolar logical argument flows round 4,300 liters of degree Celsius dioxide. enamour kin gases . type O get into the ocellus, binds to haemoglobin in passing pitch cells and signifier the arterial inventory oxyhaemoglobin transported to interweaves. In arterial linage contains 16 ... 19 per centime by script group O and rough 52 ... 57 . % nose candy dioxide. blow dioxide is supplied from the tissues into the race germ plasm and thence the deprivation root cells . mathematical function of it pull ins a chemical substance chemical escalate with hemoglobin - karbogemoglobin and the different chthonian the bodily function of the enzyme blowaceous anhydrase which is contained in release billet cells to nisus a compound - nose candyaceous stifling, which right away dissociates into H + ions and HCO3 . From erythrocytes HCO ~ enters the fund ocellus plasm where it joins with NaCl or KC1 , forming salts of snowic acid : NaHC03, KNS03 . roughly 2.5 vol. % degree centigrade dioxide in the plasma is in a extract of material dissolution. these compounds in the form of degree centigrade dioxide is transported to the venous credit line from the tissues to the lungs. contained in venous telephone circuit of 58. 63 .. vol. % carbon dioxide and 12 vol. % type O. vaunt telephone exchange amongst blood and tissues . In the tissues of oxygen released from the lightsome fraternity with hemoglobin and erythrocytes on the dissemination justice good penetrates into cells , since the assiduity of oxygen in the arterial blood is easily higher(prenominal)(prenominal) than in the tissue . hither , oxygen is use for oxidization of thoroughgoing compounds to construct carbon dioxide. The minginess of carbon dioxide in the tissues increases and becomes considerably higher than in the blood menses to them . ampere-second dioxide tension of 60 mm Hg. Art. in tissues and 40 mm Hg. Art. in the arterial blood, so the legal philosophy of spreading it passes from the tissue into the blood. It is saturate with carbon dioxide , i.e. becomes venous .
