Question 1 Report

Which of the following is an effect of carbon monoxide on man?
Answer Details
The correct answer is: "Reducing oxygen carrying capacity of blood." Carbon monoxide is a poisonous gas that can be emitted from incomplete combustion of fuels such as coal, wood, and gasoline. When inhaled, it binds to the hemoglobin in red blood cells, forming carboxyhemoglobin, which reduces the amount of oxygen that can be transported in the blood. This can lead to oxygen deprivation in various organs and tissues, which can have serious health consequences, including headache, dizziness, weakness, nausea, and even death.
