What is the target system of immunotoxicants?

• A. Cardiovascular system
• B. Respiratory system
• C. Nervous system
• D. Immune system

Answer: (D)

Immunotoxicants specifically target the immune system, which is crucial for the body's defense against pathogens and other harmful agents. These substances can impair the immune response, making the body more susceptible to infections and diseases. The immune system is made up of various cells, tissues, and organs that work together to protect the body, and exposure to immunotoxicants can disrupt this balance, leading to health issues such as increased allergies, autoimmune diseases, and diminished vaccine efficacy. Understanding this relationship is essential for recognizing the risks associated with exposure to different hazardous materials and the importance of personal protective equipment and protocols during HAZMAT incidents.
