Presentation Transcript

  1. Anatomy and Physiology

  2. Anatomy and Physiology Turn to a neighbor and talk about: • What you think you will learn about in this class • The definition of anatomy • The definition of physiology

  3. Biology • Study of life • Requirements: • Water • Food • Oxygen • Heat • Pressure • Functions: • Responsiveness • Growth • Reproduction • Movement • Metabolism (Respiration, Digestion, Excretion, etc.)

  4. Anatomy • “a cutting open” in Greek • Studies the field of structure (morphology)

  5. Physiology • Studies the performance or function

  6. Anatomy and Physiology • “Form and Function”

  7. Levels of Organization and Organ Systems

  8. Levels of Organization • Chemical/Molecular • Cellular • Tissue – cells performing specific function • Organ – tissues performing specific function • Organ System • Organism

  9. How many organ systems can you name?

  10. Organ Systems • Integumentary • Skeletal • Muscle • Nervous • Endocrine • Cardiovascular • Lymphatic • Respiratory • Digestive • Urinary • Reproductive (male and female)

  11. Integumentary • Epidermis (skin), hair, nails • Protects against environmental hazards, controls body temp

  12. Skeletal System • Bones, cartilage • Provides support, protects tissues, stores minerals, forms blood

  13. Muscular System • Muscles, tendons • Allows locomotion, provides support, produces heat

  14. Nervous System • Nerves, brain, spinal cord • Directs immediate response to stimuli, usually coordinates activities of other systems

  15. Endocrine System • Glands • Directs long-term changes in activities of other organ systems

  16. Cardiovascular System • Heart, blood vessels, blood • Transports cells and dissolved materials (nutrients, wastes, gases)

  17. Lymphatic System • Lymphatic vessels and nodes, spleen, thymus • Defends against infection and disease, returns tissue fluid to bloodstream

  18. Respiratory System • Nasal cavities, pharynx, larynx, trachea, bronchi, lungs • Delivers air to sites where gas exchange can occur between the air and circulating blood

  19. Digestive System • Salivary glands, pharynx, esophagus, stomach, intestine, liver, gallbladder, pancreas • Processes food and absorbs nutrients

  20. Urinary System • Kidneys, ureters, urinary bladder, urethra • Eliminates excess water, salts and waste products

  21. Reproductive System • Male: testes, accessory organs, external genitalia (penis, scrotum) • Female: ovaries, uterine tubes, uterus, vagina, external genitalia (clitoris, labia), mammary glands • Produces sex cells and hormones

  22. Homework Coloring Workbook – Chapter 1 • Numbers 3-7 and #20 • Cross off #9 – we will not be doing that question An Introduction to Anatomy and Physiology – Chapter 1 • Objectives 1-4
