Answer 2

****Heyy friend here is ur answer****
Carbon monoxide is the by-product of burning, heating. Carbon Monoxide is so dangerous because the body may not even notice it has gotten into the blood.  Generally your Blood Cells carry oxygen throughout the body.  The issue is that the body cannot tell the difference between CO and Oxygen.  Therefore, CO can attach itself to the blood cells and travel through the body.  When this happens, the body does not get the oxygen it needs and can cause the dizziness and passing out.

At this point, the body cannot bring in new oxygen, which can lead to death if not treated which is why it is very important to call for help.
