Explanation: The specific danger posed by carbon monoxide is that red blood cells will absorb carbon monoxide and turn away oxygen. As a result, oxygen starvation inside the human body occurs which will ultimately cause cellular death. Should this occur at high enough concentrations, affected individuals will eventually suffocate.
High concentrations of carbon monoxide kill in less than five minutes. At low concentrations it will require a longer period of time to affect the body. Exceeding the EPA concentration of 9 ppm for more than 8 hours is suspected to produce adverse health affects in persons at risk.
The shoulder joint is formed by the articulation of the head of the humerus with the glenoid cavity (or fossa) of the scapula. This gives rise to the alternate name for the shoulder joint – the glenohumeral joint.
