1. Hemoglobin is necessary for transport of carbon dioxide and carbonic anhydrase for transport of oxygen
2. Hemoglobin is necessary for transport of oxygen and carbonic anhydrase for transport of oxygen and carbonic anhydrase for transport of carbon dioxide
3. Only oxygen is transported by blood
4. Only carbon dioxide is transported by blood
Hemoglobin is necessary for transport of oxygen and carbonic anhydrase for transport of oxygen and carbonic anhydrase for transport of carbon dioxide
1. C: arterial capillary – passes oxygen to tissues
2. A: alveolar cavity – main site of exchange of respiratory gases
3. D: capillary wall – exchange of O2 and CO2 takes place here
4. B: red blood cell – transport of CO2 mainly
A: alveolar cavity – main site of exchange of respiratory gases
1. Excess of dissolved oxygen
2. Excess of TDS
3. Excess of chloride
4. Methenoglobin
Methenoglobin
1. In insects, circulating body fluids serve to distribute oxygen to tissues
2. The residual air in lung slightly decreases the efficiency of respiration in mammals
3. The principle of counter current flow facilities efficient respiration in gills of fishes
4. The presence of non- respiratory air sacs, increases the efficiency of respiration in birds
In insects, circulating body fluids serve to distribute oxygen to tissues

1. Acts as a reserve during muscular exercise
2. Raises the Pco2 of blood to 75 mm of Hg
3. Is enough to keep oxy hemoglobin saturation at 96%
4. Helps in releasing more O2 to the epithelial tissues
Is enough to keep oxy hemoglobin saturation at 96\%
