Like the original, this Louisville Slugger has hit a few out of the park. Living up to its mandate by the Kentucky General Assembly to be a "preeminent metropolitan research university," the University of Louisville (U of L) is home to the first self-contained artificial heart implant and the first successful hand transplant. A major focus of U of L is health care, and the University of Louisville Hospital is a part of the school's medical program. U of L offers associate, baccalaureate, master's, professional, and doctorate degrees in some 170 fields of study. It has more than 21,000 students (with an 18:1 student-teacher ratio) enrolled in about a dozen colleges and schools on three campuses.
