When organisms are exposed to pesticides, these chemicals can be absorbed through the skin, inhaled, or ingested. Once inside the body, pesticides interact with various tissues and organ systems. Histological studies often reveal changes at the cellular level, including alterations in cell morphology, necrosis, apoptosis, and even carcinogenesis. For instance, exposure to certain insecticides can lead to liver damage, as evidenced by histological changes such as hepatocyte swelling and increased lipid deposits.
