How does our body systems work together to keep us alive?
What are the roles of certain body systems?

HS-LS1-2 From Molecules to Organisms: Structures and Processes
Develop and use a model to illustrate the hierarchical organization of interacting systems that provide specific functions within multicellular organisms.

A connection to the SAT can be made through the application of logical reasoning and critical analysis skills tested in the SAT Reading section. Understanding feedback mechanisms, both positive and negative, involves recognizing how systems self-regulate in response to changes, which mirrors the SAT's emphasis on analyzing cause-and-effect relationships and drawing conclusions based on evidence. In the SAT Science section, students are asked to evaluate data and identify patterns, much like they would when examining the role of feedback mechanisms in maintaining homeostasis. Additionally, the SAT Reading section assesses students' ability to understand how different ideas are connected, similar to how feedback loops connect internal behaviors to external environmental conditions. This requires both comprehension and the ability to analyze complex systems.

LS1.A: Structure and Function

Feedback mechanisms maintain a living system’s internal conditions within certain limits and mediate behaviors, allowing it to remain alive and functional even as external conditions change within some range. Feedback mechanisms can encourage (through positive feedback) or discourage (negative feedback) what is going on inside the living system.
