Elaine Marieb's clearly written and comprehensive lab manuals guide students through well-planned lab activities and feature new illustrations and full-color photographs that help students visualize and master lab concepts. Designed to stand alone or for use with other materials, each manual contains anatomical and physiological terminology essential for use in one- or two-semester anatomy and physiology courses. NEW! PhysioEx™ V4.0 will now include an entirely new laboratory simulation on Acid/Base Balance that focuses on respiratory and metabolic acidosis and alkalosis, as well as renal and respiratory compensation. The lab is accompanied by a written exercise. REVISED! The Histology tutorial now features 40 new slides plus written worksheets to increase student comprehension. PhysioEx™ V4.0 is available in CD-ROM format and on the Web at www.physioex.com.
