Life Science - Human Body Structure and Function
Disciplinary Core Ideas (NGSS)
LS1.A: Structure and Function
• In multicellular organisms, the body is a system of multiple interacting subsystems. These subsystems are groups of cells that work together to form tissues and organs that are specialized for particular body functions.
Science and Engineering Practices (NGSS)
Engaging in Argument from Evidence
Engaging in argument from evidence in 6–8 builds on K–5 experiences and progresses to constructing a convincing argument that supports or refutes claims for either explanations or solutions about the natural and designed world(s).
• Use an oral and written argument supported by evidence to support or refute an explanation or a model for a phenomenon.
Crosscutting Concepts (NGSS)
Systems and System Models
• Systems may interact with other systems; they may have sub-systems and be a part of larger complex systems.
Connections to Nature of Science
Science is a Human Endeavor
• Scientists and engineers are guided by habits of mind such as intellectual honesty, tolerance of ambiguity, skepticism, and openness to new ideas.
Performance Expectations (NGSS)
MS-LS1-3 From Molecules to Organisms: Structures and Processes
Students who demonstrate understanding can:
MS-LS1-3. Use argument supported by evidence for how the body is a system of interacting subsystems composed of groups of cells.
[Clarification Statement: Emphasis is on the conceptual understanding that cells form tissues and tissues form organs specialized for particular body functions. Examples could include the interaction of subsystems within a system and the normal functioning of those systems.] [Assessment Boundary: Assessment does not include the mechanism of one body system independent of others. Assessment is limited to the circulatory, excretory, digestive, respiratory, muscular, and nervous systems.]

LE 1.1e Cells are organized for more effective functioning in multicellular organisms. Levels of organization for structure and function of a multicellular organism include cells, tissues, organs, and organ systems.
LE 1.1g Multicellular animals often have similar organs specialized systems for carrying out major life activities.
LE 1.2a Each system is composed of organs and tissues which perform specific functions and interact with each other, e.g., digestion, gas exchange, excretion, circulation, locomotion, control, coordination, reproduction, and protection from disease.
LE 1.2b Tissues, organs, and organ systems help to provide all cells with nutrients, oxygen, and waste removal.
LE 1.2c The digestive system consist of organs that are responsible for the mechanical and chemical breakdown of food. The breakdown process results in molecules that can be absorbed and transported to cells.
LE 1.2d During respiration, cells use oxygen to release energy stored in food. The respiratory system supplies oxygen and removes carbon dioxide (gas exchange).
LE 1.2e The excretory system functions in the disposal of dissolved waste molecules, the elimination of liquid and gaseous wastes, and the removal of excess heat energy.
LE 1.2f The circulatory system moves substances to and from cells, where they are needed or produced, responding to changing demands.
LE 1.2g Locomotion, necessary to escape danger, obtain food and shelter and reproduce is accomplished by the interaction of the skeletal and muscular systems, and coordinated by the nervous system.
LE 1.2h The nervous and endocrine systems interact to control and coordinate the body’s responses to changes in the environment, and to regulate growth, development, and reproduction Hormones are chemicals produced by the endocrine system; hormones regulate many body functions
LE 1.2i The male and female reproductive systems are responsible for producing sex cells necessary for the production of offspring.
LE1.2j Disease breaks down the structures or functions of an organism. Some diseases are the result of failures of the system. Other diseases are the result of damage by infection from other organisms (germ theory). Specialized cells protect the body from infectious disease. The chemicals they produce identify and destroy microbes that enter the body.
