Question : Howis oxygen and carbon dioxide transported in human beings ?

Answer»

Solution :Oxygen and carbon dioxide are two metabolic gases. Oxygen is required by everylivingcell for cellular respiration whereas `CO_(2)`is formed as a by-product and has to be eliminated from the body. In human beings, a pigment HAEMOGLOBINIS present in red blood corpuscles which has a strong affinity for oxygen, takesup the oxygen from the air in the LUNGS and CARRY it to tissues whichare deficient in oxygen.Some`O_(2)`istransported in DISSOLVED state in blood plasms. Carbon dioxide whichis more SOLUBLE in water than oxygen is mostly transported in the dissolved state in our blood. Some `CO_(2)`is transported by haemoglobin as carbaminohaemoglobin .
