उत्तर
Tobacco’s nicotine causes the adrenal glands to release more adrenaline and noradrenaline into the bloodstream, which raises blood pressure and quickens the heartbeat. Smoking lowers the concentration of hemoglobin-bound oxygen and raises the blood’s carbon monoxide (CO) level. The body has an oxygen shortage as a result.
