Cadmium is dangerous pollutant in environment because it is difficult to excrete out of the body. It causes disease in humans and animals. When the body absorbs large quantities of cadmium or when constantly exposed to small quantities, it is toxic to the body. Cadmium affects many parts of the body, the most important of which are the liver, kidneys, lungs, and testes. Both the liver and the kidney are considered organs to excrete toxins, such as heavy metals. Therefore, they are most influenced by cadmium. This study focuses on the toxicity of cadmium in the liver, kidneys, lungs and testes and its toxic effects on the histological, cellular, and functional level of each organ. We will discuss the mechanism through which cadmium causes damage to the organs of the body and the interaction that results from it.
