verb
suffocate
SUF-uh-kayt/ˈsʌfəkeɪt/
To deprive someone of breathable air.

Etymology
The “up” and “throat” pieces express the original image “narrow up”: constricting the passage for air. That choking image underlies the sense of dying, or causing death, through lack of air.
In context
if a person inhales too much carbon monoxide the blood becomes unable to carry the oxygen this can cause the cells in the vital organs to suffocate and die
