How do blood agents affect the body?

  1. By increasing oxygen levels

  2. By preventing normal oxygen utilization

  3. By altering blood flow

  4. By destroying red blood cells

The correct answer is: By preventing normal oxygen utilization

Blood agents are toxic substances that interfere with the body’s ability to use oxygen effectively. They disrupt the biochemical processes that allow cells to utilize oxygen for respiration, which can lead to cellular asphyxiation even in the presence of sufficient oxygen levels in the blood. When a blood agent enters the bloodstream, it typically works by binding to hemoglobin or other components involved in the oxygen transport and utilization process, such as cytochrome c oxidase. This impedes the ability of the cells to convert oxygen into usable energy, resulting in oxygen deprivation at the cellular level. Due to this mechanism of action, individuals exposed to blood agents may suffer from symptoms of hypoxia, regardless of the actual amount of oxygen available in the air they are breathing. This highlights the critical importance of recognizing and responding to exposures to these hazardous materials promptly and effectively to mitigate their lethal effects.
