Toxicology The cardiovascular system
The cardiovascular system • Maintain internal homeostasis. • Regulate body temperature • Maintain tissue and cellular pH.
Cardiac cell type • Cardiac fibroblast • Vascular cells • Purkinje cells • Connective tissue cells • Cardiac myocytes
Cardiomypathy Peripartum Cardiomyopathy Alcoholic Cardiomyopathy
Effects of toxicants on the cardiovascular system There are several different injury mechanism associated with cardiac toxicants. • Generation of free redicals • Lipid peroxidation • Impaired membrane integrity • Mitochondrial dysfunction • Sarcoplasmic reticulum dysfunction • Altered calcium homeostasis
Blood toxicology • Direct and indirect damage to the hematopoietic system may produce hypoxia, hemorrhage, infection and death. • Primary hematotoxicity • Secondary hematotoxicity
