The system could be a network of glands and organs that produce, store, and secrete hormones. When functioning normally, the system works with other systems to manage your body's healthy development and performance throughout life. Endocrine-disrupting chemicals (EDCs) are substances within the environment (air, soil, or water supply), food sources, care products, and made products that interfere with the conventional function of your body’s system. EDCs are chemicals or mixtures of chemicals that interfere with the way the body’s hormones work. Some EDCs act like "hormone mimics" and trick our body into thinking that they're hormones, while other EDCs block natural hormones from doing their job. Other EDCs can increase or decrease the amount of hormones in our blood by affecting how they're made, countermined, or stored in our body. Finally, other EDCs can change how sensitive our bodies are to different hormones.
