Question

Given below are statements that describe the working of a breath analyser to detect alcohol content in the human body. Arrange the process of alcohol detection in a correct sequence:

• A. 2, 6, 4, 5, 1, 3
• B. 6, 1, 2, 5, 4, 3
• C. 5, 6, 3, 4, 1, 2
• D. 6, 5, 2, 1, 4, 3

Answer 1

The correct option is D 6, 5, 2, 1, 4, 3

Alcohol goes to the stomach and the blood absorbs the alcohol. The blood transports alcohol to all the body's internal systems to reach the brain. It is also absorbed in the lungs in the form of vapour. Alcohol is then exhaled along with carbon dioxide which is sensed by the breath analyser.
