  1. Body Parts An Organ System Overview

  2. Levels of Structural Organization

  3. Body Covering - The skin you’re in! • Integumentary • Forms the external body covering • Protects deeper tissue from injury • Synthesizes vitamin D • Location of cutaneous nerve receptors

  4. Support and Movement – dem Bones! • Skeletal • Protects and supports body organs • Provides muscle attachment for movement • Site of blood cell formation • Stores minerals

  5. Support and Movement – feel the groove! • Muscular • Allows locomotion • Maintains posture • Produces heat

  6. Integration and Coordination • Nervous • Fast-acting control system • Responds to internal and external change • Activates muscles and glands

  7. Integration and Coordination • Endocrine • Secretes regulatory hormones • Growth • Reproduction • Metabolism

  8. Transport – the super Highways! • Cardiovascular • Transports materials in body via blood pumped by heart • Oxygen • Carbon dioxide • Nutrients • Wastes

  9. Transport - the super highways! • Lymphatic • Returns fluids to blood vessels • Disposes of debris • Involved in immunity

  10. Absorption and Excretion • Digestive • Breaks down food • Allows for nutrient absorption into blood • Eliminates indigestible material

  11. Absorption and Excretion • Respiratory • Keeps blood supplied with oxygen • Removes carbon dioxide

  12. Absorption and Excretion • Urinary • Eliminates nitrogenous wastes • Maintains acid – base balance • Regulation of materials • Water • Electrolytes

  13. Reproduction • Reproductive • Production of offspring

  14. Characteristics of Life Traits shared by all organisms Movement– change in position; motion Responsiveness– reaction to a change Growth– increase in body size; no change in shape Reproduction– production of new organisms and new cells Respiration – obtaining oxygen; removing carbon dioxide; releasing energy from foods

  15. Characteristics of Life Traits shared by all organisms Digestion – breakdown of food substances into simpler forms Absorption – passage of substances through membranes and into body fluids Circulation – movement of substances in body fluids Assimilation– changing of absorbed substances into chemically different forms Excretion – removal of wastes produced by metabolic reactions

  16. Examples of selected interrelationships among body organ systems.

  17. The Organ System Matching Game!! Match the organ systems that work together Digestive System Endocrine System Reproductive System Circulatory System Skeletal System Urinary System Respiratory System Muscular System All systems work together to maintain life.
