Biology, Unit 2: Organs and Organ Systems

Our bodies are composed of cells, tissues, organs, and organ systems that are essential in maintaining homeostasis. In this unit, students will learn about levels of organization in the body, how structure determines function, and how the digestive, circulatory, nervous, immune, and endocrine systems work to maintain homeostasis. Lessons, quizzes, and virtual labs help students master the essential concepts while a homeostasis video project helps students apply them.
