What is a primary characteristic of blood agents?

• A. They primarily cause skin burns
• B. They disrupt respiratory function
• C. They affect both the nervous and digestive systems
• D. They have long-term environmental impacts

Answer: (B)

Blood agents are chemical compounds that interfere with the body's ability to carry oxygen. Their primary mechanism of action is to disrupt respiratory function by affecting hemoglobin, the molecule in red blood cells responsible for transporting oxygen. When blood agents, such as cyanide or carbon monoxide, are inhaled or absorbed, they can prevent the proper utilization of oxygen at the cellular level, leading to hypoxia and potentially fatal outcomes. This characteristic distinguishes blood agents from other hazardous substances that may cause injuries like burns or affect different systems of the body. Therefore, understanding the specific impact of blood agents on respiration helps differentiate them from other types of chemical agents that may have different effects.
