The course objective is to introduce students to several major body systems, including the cardiovascular, urinary, respiratory, gastrointestinal, and reproductive systems, with particular emphasis on the endocrine and immune systems. The components and functions of each of these systems are reviewed, along with diseases and conditions that affect them. The drugs that are used to treat such conditions are studied with respect to their mechanisms of action, therapeutic effects, and adverse effects. As students work through this course, their understanding of the ways in which drugs act on the body will improve.
