Vedclass · Answer

(D) Cigarette smoke contains carbon monoxide $(CO)$,which is a poisonous gas.When inhaled,$CO$ binds to hemoglobin in the red blood cells with an affinity approximately $200$ to $250$ times greater than that of oxygen.This forms carboxyhemoglobin,which reduces the oxygen-carrying capacity of the blood,leading to hypoxia and various cardiovascular issues.Therefore,excessive smoking significantly increases the concentration of $CO$ in the blood.

Excessive smoking leads to an increase in the concentration of which substance in the blood?
