The primary effect of a Blood Chemical Agent is that it interferes with oxygen transfer within the body. These agents are designed to disrupt the normal function of red blood cells and impede the body's ability to utilize oxygen. They do this by affecting the hemoglobin's ability to carry oxygen, leading to a decrease in oxygen delivery to tissues and organs. This can result in symptoms like weakness, confusion, and even loss of consciousness as the body struggles with inadequate oxygen supply. The critical aspect of these agents is their mechanism of action at the blood level, which is distinct from other types of chemical agents that may cause irritation or inflammation in different body systems.
