  9. Semester Project: • One of the objectives of the course is to ascertain knowledge of diseases and disorders which affect the major body systems. • The semester project will give the student an opportunity to study and learn about a particular disease state. • The semester project will link the vocabulary you learn throughout the semester to real-life medicine. Dr Atef Masad

  10. Components of the Project: • A written paper describing the disease state. This paper should be no longer than 3 pages, typewritten, size 12 font. • The written paper should include a bibliography in the standard format. Dr Atef Masad

  11. An oral presentation • You will give a 10-15 minute presentation to the class about your selected disease/topic. • You should stress how the disease presents, how it is diagnosed, what system and organs are affected, how it is treated, and a discussion about how the disease relates to this course. • The presentation may be a poster board or PowerPoint type.
