Study Notes
Anatomy
- Defined as the study of the structure of organisms and their parts.
- Etymology: Derived from Ancient Greek "ana" (apart) and "temuein" (to cut).
- Types of anatomy:
- Gross Anatomy: Focuses on large, visible structures like organs and tissues.
- Microscopic Anatomy: Studies structures too small to see without a microscope, including cells and molecules.
- Developmental Anatomy: Explores structural changes from conception to adulthood.
- Comparative Anatomy: Examines similarities and differences between species.
Physiology
- Scientific study of functions and mechanisms in living systems.
- Originates from Ancient Greek "phúsis" (nature) and "-logía" (study of).
- Investigates how body parts operate individually and collectively to maintain life.
Relationship Between Anatomy and Physiology
- Concept summarized as "form follows function": structure (anatomy) is intricately linked with its purpose (physiology).
- Examples:
- Heart's muscular walls are adapted for pumping blood.
- Bone shapes aid in movement and protection.
Levels of Structural Organization
- Organized into distinct levels:
- Chemical Level: Atoms combine to form molecules, creating organelles in cells.
- Cellular Level: Cells are the basic units of life, each with specialized functions.
- Tissue Level: Tissues consist of similar cells working together for specific functions.
- Organ Level: Organs are composed of multiple tissue types collaborating for designated functions.
- System Level: Organ systems consist of various organs performing complex tasks collectively.
- Organismal Level: The totality of all structural levels functioning together to support life.
Organ System Overview
- Major organ systems and their functions:
- Integumentary System: Protects the body; encompasses skin, hair, and nails.
- Skeletal System: Provides structural support; includes bones and joints.
- Muscular System: Enables movement; comprises skeletal, smooth, and cardiac muscles.
- Circulatory System: Transports blood and nutrients; includes the heart and blood vessels.
- Lymphatic System: Recycles excess fluid into the bloodstream; features lymph nodes and vessels.
- Respiratory System: Facilitates gas exchange; involves the lungs and trachea.
- Digestive System: Breaks down food for nutrient absorption; includes the stomach and intestines.
- Urinary System: Eliminates waste; consists of kidneys and bladder.
- Immune System: Protects against disease; relies on white blood cells and immune responses.
- Organ systems collaborate to maintain homeostasis and ensure survival, with their structures supporting their functions.
