 Chirality is also seen in the study of facial asymmetry.In the case of the health condition "situs inversus totalis", in which all the internal organs are flipped horizontally (i.e.the heart placed slightly to the right instead of the left), chirality poses some problems should the patient require a liver or heart transplant, as these organs are chiral, thus meaning that the blood vessels which supply these organs would need to be rearranged should a normal, non "situs inversus" organ be required.
