Which system can be severely disrupted when a person intakes synthetic mimics? 

A)  the circulatory system 
B)  the digestive system 
C)  the endocrine system 
D)  the respiratory system

Synthetic mimics, also known as synthetic hormones, can severely disrupt the endocrine system. This is because synthetic hormones are chemically different from the hormones naturally produced by the body and can interfere with the regulation of bodily processes such as growth, metabolism, and reproduction. Long-term use of synthetic hormones can lead to a range of negative health effects, including an increased risk of cancer and cardiovascular disease. The circulatory, digestive, and respiratory systems are not directly impacted by synthetic hormone intake.
