Physiology is the study of the functions of body parts.
How are anatomy and physiology interdependent?
How are anatomy and physiology interdependent?
Anatomy and physiology are interdependent because if we alter any of the levels, we interfere with physiology.

Study Notes
Anatomy and Physiology
- Anatomy studies body structures while physiology examines the functions of those structures.
- The relationship between anatomy and physiology highlights that the design of body parts influences their capabilities (e.g., hand structure allows for grasping).
Levels of Organization
- Atoms: The smallest particles of elements.
- Molecules: Composed of two or more bonded atoms.
- Macromolecules: Large molecules like proteins, starches, or nucleic acids.
- Cells: The basic structural and functional units of organisms.
- Tissues: Groups of similar cells that perform specialized functions.
- Organs: Structures made of two or more tissues with specific functions.
- Organ Systems: Groups of organs working together for specialized functions.
- Organisms: Individual living entities comprising various systems and organs.
Core Themes in Anatomy and Physiology
- Cells: All organisms consist of cells; their survival depends on favorable internal conditions.
- Internal Environment: The body’s internal environment, including intracellular and extracellular fluids, must remain relatively constant for cell survival.
- Homeostasis: The body maintains stable internal conditions, crucial for overall cellular function and organism health.
- Interdependency of Cells: Different cell types rely on each other for homeostasis; dysfunction in one type can impact others (e.g., heart attack affecting heart cells).
- Structure and Function: Anatomy provides insights into physiological functions, revealing the interconnected relationship between the two.
- Gradients and Permeability: Substances move based on gradients; membrane permeability is vital for cell function.
- Cellular Differentiation: Different cell types produce specific proteins that determine their roles and capabilities.
- Cell Membrane Mechanisms: Cell membranes regulate what enters and exits, responding selectively to signals.
- Cell-to-Cell Communication: Essential for coordinating functions, communication occurs through receptors on cell membranes.
- Feedback Loops: Internal environment changes trigger signals between cells to restore balance; loops can be negative or positive.
- Balance: Maintaining a steady internal environment requires continual replacement and removal of substances.
- Energy Process: All biological processes require energy.
Homeostasis in Humans
- Homeostasis ensures a stable internal environment vital for health.
- The internal environment varies based on components such as temperature and pH, which are tightly regulated.
- Homeostatic mechanisms involve sensors, control centers, and effectors working together to maintain stability through feedback systems.
