Topic : Structure and Function of Living Systems Vocabulary Learning Objectives 7.12A Investigate and explain how internal structures of organisms have adaptations that allow specific functions such as gills in fish, hollow bones in birds, or xylem in plants. 7.12B Identify the main functions of the systems of the human organism, including the circulatory, respiratory, skeletal, muscular, digestive, excretory, reproductive, integumentary, nervous, and endocrine systems. Supporting Standard 7.12E Compare the functions of a cell to the functions of organisms such as waste removal. Real – World Adaptation – a change in structure or habits, often hereditary, by which an organism improves its condition in relationship to its environment Circulatory system – transports nutrients and oxygen to the body Digestive system – breaks down food to provide nutrients and energy Endocrine system – regulates the body with hormones Excretory system – removes waste from the body Integumentary system – provides protection of the body Muscular system – provides movement of the body Nervous system – controls and coordinates the body Reproductive system – produces offspring Respiratory system – exchanges oxygen and carbon dioxide Skeletal system – provides structure and protection for the body System – interacting, interrelated, or interdependent elements forming a more complex whole Unit Questions Why is it important for us to know the structure and function of living things? What are some important factors that help us distinguish the function of living things? Language Objectives I will use visual and contextual support and support from peers and teachers to develop my understanding of living things What are the main functions of the systems of the human organism? In what ways do the structures and functions of human systems differ? How do various organ systems work together in living things? In what ways are internal structures of organisms adapted to perform specific functions? I will speak and write using grade-level content area vocabulary in context of the key ideas.
