    Chapter 1 Chapter 1 Presentation Transcript

    • Chapter 1: Body Orientation & Anatomical Terminology Human Anatomy & Physiology S. Franklin-Jones
    • Anatomy
      • the study of structure and shape of the body and body parts and their relationships to one another
          • Gross anatomy- study of large body structures.
            • Heart, bones
          • Microscopic anatomy- study of small body structures
            • Cells and tissue
    • Physiology
      • the study of how the body and its parts work or function
          • Neurophysiology- explains working of the nervous system
          • Cardiac physiology- studies the function of the heart
    • Levels of Organization
      • Atoms: tiny building blocks of matter
      • Cells: the smallest units of all living things
      • Tissues: groups of similar cells that have a common function, ex. muscle, nerves
      • Organ: a structure composed of two or more tissue types that perform a specific function for the body, ex. brain
      • Organ System: a group of organs that cooperate to accomplish a common function, ex. Circulatory System
      • Organism: all organ systems that make up living body
    • Integumentary: skin
      • Waterproof, cushions, protection
      • Regulation of temperature
      • Temperature, pressure, and pain receptors
    • Skeletal
      • bones, cartilage, ligaments, and joints
      • Supports body and allows for movement
      • Protection of organs
      • Formation of blood cells and storage of minerals
    • Muscular
      • only one function, to contract or shorten
    • Nervous
      • brain, spinal cord, and sensory receptors
      • Detect stimuli and respond to it by activating the appropriate muscles or glands
            • the body’s fast-acting control system
            • nerve impulses- electrical signals
            • central nerve system- brain and spinal cord
              • receives and responds
    • Endocrine
      • produce hormones to control body activities
            • Hormones- chemical molecules produced by endocrine glands
            • The endocrine glands:
              • Pituitary

              • Pineal
              • Ovaries and testes
            • Growth, reproduction, and food use by cells are controlled by hormones.
    • Circulatory
      • includes the cardiovascular and lymphatic
          • Cardiovascular System- distributes blood to all the parts of the body
            • Includes the heart and the blood vessels
            • Carries oxygen, nutrients, hormones, and other substances
            • White blood cells help to protect the body for toxins, bacteria, and tumor cells
          • Lymphatic System- consists of lymphatic vessels, lymph nodes, and other lymphoid organ and tissues
            • Lymphatic vessels returns the fluid leaked from the blood back to the blood vessels so blood can keep circulating
            • Lymph nodes and lymphoid organs help cleanse the blood and house cells involved with immunity
      • Transport and delivery system
      • Protect the body from foreign invaders

              • lungs
    • Digestive
      • tube running from the mouth to the anus
      • Break down food and disperse food particles to cells
      • Removal of undigested food

              • small and large intestines
              • rectum
    • Urinary
      • removes all nitrogen containing wastes from the blood and flushes them from the body as urine
      • - Consists of:
              • Kidneys
              • Ureters
              • Bladder
              • Urethra
