    Explanation (300 words)<\/strong><\/h3>\n\n\n\n

    Carbon dioxide is a byproduct of cellular metabolism and must be transported from tissues to the lungs for exhalation. This process occurs in three main forms: dissolved CO\u2082 in plasma (7-10%), chemically bound to hemoglobin as carbaminohemoglobin (20-30%), and as bicarbonate ions in plasma (60-70%).<\/p>\n\n\n\n

      \n
    1. Diffusion<\/strong>: CO\u2082 diffuses from metabolically active tissues into the blood due to its concentration gradient.<\/li>\n\n\n\n
    2. Inside RBCs<\/strong>: Most CO\u2082 enters red blood cells. There, carbonic anhydrase catalyzes its reaction with water to form carbonic acid (H\u2082CO\u2083).<\/li>\n\n\n\n
    3. Dissociation<\/strong>: Carbonic acid rapidly dissociates into bicarbonate ions (HCO\u2083\u207b) and hydrogen ions (H\u207a). To balance charge, HCO\u2083\u207b diffuses out of RBCs into the plasma, and chloride ions (Cl\u207b) move into the RBCs (chloride shift).<\/li>\n\n\n\n
    4. At the lungs<\/strong>: The reverse occurs. Bicarbonate reenters RBCs, combines with H\u207a to reform H\u2082CO\u2083, which is then converted back into CO\u2082 and H\u2082O. The CO\u2082 diffuses into the alveoli and is exhaled.<\/li>\n<\/ol>\n\n\n\n

      This dynamic process ensures efficient CO\u2082 transport, buffering blood pH through bicarbonate, and maintaining homeostasis.<\/p>\n","protected":false},"excerpt":{"rendered":"
