Question
Chapter 20.3, Problem 13AYP
Summary Introduction
To determine:
The valves separating atria from ventricles and the roles of papillary muscles and chordae tendineae.
Introduction:
The human heart has atrioventricular valves and semilunar valves. Tricuspid and bicuspid are the two types of atrioventricular valves.
