Hi1 Anno. You don't tell us what level  are your students. If they are in the elementary level , I think you can teach them vocabulary. Melody's post of medical tittle and abbreviation is very useful. It recalls me of the first  lesson of the fist year of my medicine studying. We learnt about " general practitioner". In our country, we call it  "All of branches " doctor { General doctor}.  Specialists are always regarded as the first range of doctors . People always think they were belong to the brilliant students.....I was very proud to explain to the last -year -student of English language  about this tittle, the  generous role of General Practioner in my country and some situation of medical professionals. If your students are in the intermediate level , you can choose some readings  about merdicine such as some explanations  in the post of Boyestown about tittle and abbreviation I have read a  webpage about woman io this address: OBGYN, net . There are a lot of readings  and vocabulary about women diseases such as Urogynecology, Ovarian tumours....In my country, Doctors used to teach us about medecine English.  English teachers only teach us courses to reach intermediate or elementary  level in order to learn English in our career better
