Biology 2e is designed to cover the scope and sequence requirements of a typical two-semester biology course for science majors. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. Biology includes rich features that engage students in scientific inquiry, highlight careers in the biological sciences, and offer everyday applications. The book also includes various types of practice and homework questions that help students understand—and apply—key concepts. The 2nd edition has been revised to incorporate clearer, more current, and more dynamic explanations, while maintaining the same organization as the first edition. Art and illustrations have been substantially improved, and the textbook features additional assessments and related resources.

By the end of this section, you will be able to do the following:

Describe the structure of the heart and explain how cardiac muscle is different from other muscles
Describe the cardiac cycle
Explain the structure of arteries, veins, and capillaries, and how blood flows through the body

In this lab, the student will review the physiology of the organ systems by using images of models, experiments, and videos. Then the student will be asked to assess his or her knowledge, which can eventually be put to practical or experimental use. Upon successful completion of this lab supplement, students will be able to: describe techniques used to measure the function of organ systems; relate diagnostic tools, such as those used to measure ECG, EEG, and EMG activity, and those used in spirometry and urinalysis tests, to the physiological processes; relate diagnostic tests, such as the patellar and plantar reflex tests, to physiological processes; perform laboratory observations and experiments; collect, analyze, and interpret data; and form conclusions.
