CALIFORNIA CONTENT STANDARDS: Grade 7 5. The anatomy and physiology of plants and animals illustrate the complementary nature of structure and function. As a basis for understanding this concept: a. Students know plants and animals have levels of organization for structure and function, including cells, tissues, organs, organ systems, and the whole organism. c. Students know how bones and muscles work together to provide a structural framework for movement. 6. Physical principles underlie biological structures and functions. As a basis for understanding this concept: j. Students know that contractions of the heart generate blood pressure and that heart valves prevent backflow of blood in the circulatory system.

9. As a result of the coordinated structures and functions of organ systems, the internal environment of the human body remains relatively stable (homeostatic) despite changes in the outside environment. As a basis for understanding this concept: a. Students know how the complementary activity of major body systems provides cells with oxygen and nutrients and removes toxic waste products such as carbon dioxide. b. Students know how the nervous system mediates communication between different parts of the body and the body’s interactions with the environment. 10. Organisms have a variety of mechanisms to combat disease. As a basis for understanding the human immune response:
Students know the role of antibodies in the body's response to infection.
Students know how vaccination protects an individual from infectious
diseases. d. Students know there are important differences between bacteria and viruses with respect to their requirements for growth and replication, the body's primary defenses against bacterial and viral infections, and effective treatments of these infections.
