Organ Systems
NYS NGSS:
Multi-cellular organisms have a hierarchical structural organization, in which any one sy- stem is made up of numerous parts and is itself a component of the next level. (HS-LS1-2)
HS-LS1-2. Develop and use a model to illustrate the hierarchical organization of interacting systems that provide specific functions within multi-cellular organisms.
NYS Living Environment
Major Understandings:
1.2a Important levels of organization for structure and function include organelles, cells, tissues, organs, organ systems, and whole organisms.
1.2b Humans are complex organisms. They require multiple systems for digestion, respiration, reproduction, circulation, excretion, movement, coordination, and immunity. The systems interact to perform the life functions.
1.2c The components of the human body, from organ systems to cell organelles, interact to maintain a balanced internal environment. To successfully accomplish this, organisms possess a diversity of control mechanisms that detect deviations and make corrective actions.
1.2d If there is a disruption in any human system, there may be a corresponding imbalance in homeostasis.
1.2e The organs and systems of the body help to provide all the cells with their basic needs. The cells of the body are of different kinds and are grouped in ways that enhance how they function together.
