This document provides instructions for a dissection lab of the heart. It lists the required materials which include a heart, dowels, blade, tweezers, tray, and gloves. The method instructs students to orient and cut the heart to identify the four chambers and major blood vessels. A diagram labels the internal structures of the heart including the ventricles, septum, arteries, and veins. A worksheet matches terms like the aorta, vena cava, and valves to their descriptions. Links are provided for additional information on heart dissection procedures.
