Assertion (A): | Smoking increases the carbon monoxide (CO) content in the blood which has a greater affinity to hemoglobin than oxygen. |
Reason (R): | CO forms a stable bond with haemoglobin and does not allow the binding of oxygen. It reduces the concentration of heme bounded oxygen and causes oxygen deficiency in the body. |
