    Study Notes

    Anatomy

    • The study of the structure and shape of the body and its parts
    • Divided into two major types: gross anatomy and microscopic anatomy
    • Gross anatomy studies large body structures visible to the naked eye
      • Divided into three subcategories:
        • Surface anatomy studies external anatomical features without dissection
        • Regional anatomy focuses on specific regions of the body and how systems work together in those regions
        • Systemic anatomy focuses on the anatomy of different organ systems
    • Microscopic anatomy studies structures too small to be seen without magnification
      • Includes two important topics:
        • Cytology studies the structure and function of cells
        • Histology studies the organization and details of tissues

    Physiology

    • The study of how the body and its parts function
    • Inseparable from anatomy, as structure determines function
    • Example: the thin walls of the lungs allow for gas exchange, while the muscular heart pumps blood

    Levels of Structural Organization

    • The human body demonstrates structural complexity from the simplest to the most complex level
    • Chemical level: Atoms combine to form molecules like water, sugar, and proteins
    • Cellular level: Molecules associate to form cells, the smallest units of living things
    • Tissue level: Groups of similar cells with a common function
      • Four basic tissue types: epithelial, connective, muscular, and nervous
    • Organ level: Composed of two or more tissue types working together for a specific function
    • Organ system level: A group of organs working together to accomplish a common purpose
    • Organismal level: The highest level of structural organization, the sum total of all structural levels working together to sustain life

    Eleven Major Organ Systems

    • The human body is made up of 11 organ systems
    • Integumentary system: Includes skin, hair, and fingernails
      • Protects deeper tissues, waterproofs the body, produces vitamin D, excretes salts, helps regulate temperature, contains sensory receptors
    • Skeletal system: Composed of bones, cartilages, and joints
      • Supports the body, provides framework for movement, protects organs, produces blood cells, stores minerals
    • Muscular system: Contains muscles, responsible for movement
      • Skeletal muscles for movement of the body as a whole, other muscles for movement of fluids and substances within the body
    • Nervous system: Includes brain, spinal cord, nerves, and sensory receptors
      • Rapid-acting control system, responds to stimuli, detects changes, assesses information, activates effectors (muscles or glands)
    • Endocrine system: Consists of glands that produce hormones
      • Regulates body activities more slowly than nervous system, hormones released into blood and travel to target organs
      • Controls growth, reproduction, use of nutrients by cells
    • Cardiovascular system: Includes heart and blood vessels
      • Delivers oxygen, nutrients, hormones, picks up wastes, transports blood to all tissues
    • Lymphatic system: Includes lymphatic vessels, lymph nodes, spleen, tonsils
      • Returns fluid to bloodstream, cleanses blood, houses immune cells
    • Respiratory system: Includes nasal passages, pharynx, larynx, trachea, bronchi, lungs
      • Supplies body with oxygen, removes carbon dioxide
    • Digestive system: Includes mouth, esophagus, stomach, small and large intestines, rectum, accessory organs
      • Breaks down food, delivers nutrients to blood, reabsorbs water, eliminates waste
    • Urinary system: Removes waste by-products from the body
