Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Drinking i.e. consuming alcohol causes deposition of alcoholic fat on the walls of blood vessels due to which lumen of blood vessels get reduced. This leads to increase in blood pressure and hence, the activity of heart is increased. The heart beat and strength of heart contraction becomes fast and the person may run short of breath. This may also lead to fatigue of muscles.
So, the correct answer is 'Rapid breathing'.
