The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Effects of Smoking**: Smoking has several harmful effects on the body, particularly on the respiratory system and blood composition. When smoke is inhaled, it introduces various harmful substances into the lungs. 2. **Identifying Key Components**: One of the most dangerous components of cigarette smoke is carbon monoxide (CO). This gas is produced during the incomplete combustion of carbon-containing materials, including tobacco. 3. **Absorption of Carbon Monoxide**: When smoke is inhaled, carbon monoxide is rapidly absorbed into the bloodstream through the lungs. This absorption occurs quickly and can lead to significant health issues. 4. **Binding to Hemoglobin**: Once in the bloodstream, carbon monoxide binds to hemoglobin in red blood cells. This binding is particularly concerning because carbon monoxide binds to hemoglobin over 200 times more effectively than oxygen does. 5. **Consequences of Carbon Monoxide Binding**: The binding of carbon monoxide to hemoglobin reduces the amount of hemoglobin available to carry oxygen. As a result, the concentration of heme-bound oxygen in the blood decreases, leading to reduced oxygen delivery to tissues. 6. **Filling in the Blank**: Therefore, the correct answer to the question "Smoking increases______ content in blood and reduces the concentration of heme-bound oxygen" is "carbon monoxide". **Final Answer**: Smoking increases **carbon monoxide** content in blood and reduces the concentration of heme-bound oxygen. ---

In the following question a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as : Assertion (A): Smoking increases the carbon monoxide (CO) content in the blood which has greater affinity to haemoglobin than oxygen. Reason (R) CO forms a stable bond with haemoglobin and does not allow binding of oxygen. It reduces concentration of haem bound oxygen and causes oxygen deficiency in the body.
