Question

Why is tobacco, smoking associated with rise in blood pressure and emphysema (oxygen deficiency in the body)? Explain.

Answer 1

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.
