    Characteristics of Living Organisms

    All living organisms share common features such as growth, reproduction, responsiveness, metabolism, and homeostasis.

    Anatomy vs. Physiology

    Anatomy is the study of structure, while physiology is the study of function; they are interrelated.

    Homeostasis

    Homeostasis is the ability of the body to maintain stable internal conditions despite external changes.

    Feedback Loops

    Feedback loops are processes that help maintain homeostasis, involving components like sensors, control centers, and effectors; can be positive or negative.
