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 system of blood flow through the body
Describe how blood pressure is regulated

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

List the basic components of the blood
Compare red and white blood cells
Describe blood plasma and serum

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

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

Describe an open and closed circulatory system
Describe interstitial fluid and hemolymph
Compare and contrast the organization and evolution of the vertebrate circulatory system

Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.

In this lab, the student will review the anatomy and histology of the organs by using images of models, microscopic slides, and videos on cat and sheep dissections. The student will then be asked to assess his or her knowledge, which eventually can be put to practical or experimental use. Upon successful completion of this lab supplement, students will be able to: use anatomical terminology correctly in the laboratory; using a compound light microscope, identify different tissues and describe a human organ where that tissue can be found; describe the major features and functions of human skin; identify and name human bones and their major features and differentiate, microscopically and grossly, between compact and spongy bone; name and describe the functions of the human brain's major structures; describe the anatomical and functional differences between the dorsal and ventral roots of spinal nerves and the dorsal and ventral horns of the spinal cord's grey matter; describe the structure of an intervertebral disc; identify, microscopically and grossly, the differences between the three types of muscle and describe the respective structures and locations of different muscle tissues; identify and name the structures of the human eye and the human ear; describe the major similarities and differences in the structure of an artery and a vein; describe the flow of blood through the heart and identify all major vessels, chambers, and valves; identify and name, histologically and anatomically, the major components of the respiratory system, the digestive system, and the male and female urinary systems; identify and name, histologically and anatomically, the major components of male and female reproductive systems.
