    Study Notes

    Human Body Overview

    • The human body is studied through anatomy and physiology.
    • Anatomy investigates the body's structure (gross and microscopic).
    • Gross anatomy studies structures without a microscope.
    • Microscopic anatomy studies structures that require a microscope.
    • Physiology investigates the processes or functions of living things.

    Student Learning Outcomes

    • Students will identify the organizational hierarchy of the human body.
    • Students will identify the eleven different body systems and how they interact.
    • Students will identify and explain the characteristics of life.
    • Students will explain homeostasis and feedback loops.
    • Students will identify body regions and explain directional terms, anatomical positions.

    Anatomical Imaging Techniques

    • X-ray uses electromagnetic waves.

    Homeostasis and Negative Feedback

    • Homeostasis is the maintenance of a constant internal environment.
    • Variables fluctuate around a set point to maintain a normal range of values.
    • Negative feedback counteracts a change in a variable to help maintain homeostasis.
    • Components include stimulus, receptor, control center, effector, response.

    Positive Feedback

    • Positive feedback enhances an initial stimulus, thus causing a variable to continue in the same direction.
    • Positive feedback often controls infrequent events.
    • An example is blood clotting.
