Presentation Transcript

  1. Bellwork Grab your book and a worksheet. Have your skeleton and notes out ready to go

  2. What to expect… • Standard 8, Outline basic concepts of normal structure and function of all body systems and explain how homeostasis is maintained. TN Reading 2 • Objective: Describe functions and fractures of the skeletal system through lecture • Draw and label parts of skeletal system discussed in class Friday.

  3. Use the models provided, draw and label your diagrams with the terms we learned yesterday. • Skull (Zygomatic, Maxilla, Nasal, Lacrimal, Mandible) • Sternum (Manubrium, Body, and Xiphoid Process) • Ribs (12 pair, 10 pair true, 2 pair floating) • Spine (7 Cervical, 12 Thoracic, 5 Lumbar, Sacral, Coccyx) • Scapula • Clavicle • Humerus • Radius • Ulna • Carpals • Metacarpals • Phalanges (fingers and toes) • Hip • Femur • Patella • Tibia • Fibula • Tarsals • Metatarsals.

  4. Did we cover?? • Standard 8, Outline basic concepts of normal structure and function of all body systems and explain how homeostasis is maintained. TN Reading 2 • Objective: Describe functions and fractures of the skeletal system through lecture • Draw and label parts of skeletal system discussed in class Friday.

  5. Systems of the Body • Skeletal • Muscular • Circulatory/Cardiovascular • Respiratory • Nervous • Digestive • Urinary • Reproductive • Endocrine • Lymphatic • Integumentary

  6. What to expect… • Standard 8, Outline basic concepts of normal structure and function of all body systems and explain how homeostasis is maintained. TN Reading 2 • Objective: Describe structure of the respiratory system through lecture and diagrams. • Describe the functions of the respiratory system.

  7. RESPIRATORY SYSTEM STRUCTURES and FUNCTIONS

  8. What to expect… • Standard 8, Outline basic concepts of normal structure and function of all body systems and explain how homeostasis is maintained. TN Reading 2 • Objective: Describe structure of the respiratory system through lecture and diagrams • Describe the functions of the respiratory system.

  9. Take a deep breath… • Worksheets: • As we go over the different structures in the respiratory system, we will fill in the structures on your diagram. Make sure you are paying attention so that you don’t miss a structure.

  10. UPPER RESPIRATORY • SINUSES • NASAL CAVITY • PHARNYX • LARNYX • EPIGLOTTIS • TRACHEA

  11. Sinuses

  12. Nasal Cavity • Nares • Nasal Septum • Turbinates • Cilia • Olfactory Nerves

  13. Pharnyx • Throat • Passageway for air and food • 5” long • Nasopharnyx • Laryngopharnyx • Oropharnyx Epiglottis: Flap that closes upon swallowing

  14. Pharnyx & Larnyx

  15. Larnyx • Voice Box: Vocal Cords Adams Apple- men only Break: Place your hand on your throat, guys, you will be able to feel the apple, girls, you will only be able to fill the movement when you swallow.

  16. Trachea • Windpipe • In front of the esophagus • 4.5” long • continues to the bronchus

  17. Lower Respiratory • Bronchial Tree • R & L Bronchus • Bronchioles • Alveoli • Lungs • Pleura

  18. Alveoli • Grape like clusters • 500 million • Covered with “surfactant” • fat like material that keeps the alveoli from collapse

  19. Located in the Thoracic Cavity -Top = Apex -Bottom = Base Porous & Spongy Right > Left Lobes - Superior - Middle - Inferior Lungs

  20. Pleura • Thin, moist, and slippery • Membrane • Visceral and Parietal • Visceral covers the lungs • Parietal lines the thoracic cavity

  21. What to expect… • Standard 8, Outline basic concepts of normal structure and function of all body systems and explain how homeostasis is maintained. TN Reading 2 • Objective: Describe structure of the respiratory system through lecture and diagrams • Describe the functions of the respiratory system.

  22. FUNCTIONS • Warms and moistens air for the lungs. Occurs in the NASAL CAVITY • Allows for gas exchange between O2 and CO2. Occurs in the ALVEOLI.

  23. Mechanics of Breathing • Inhalation & Exhalation • Inhalation=inspiration...breathing IN • Exhalation= expiration...breathing OUT Diaphragm moves DOWN with INHALATION Diaphragm moves UP with EXHALATION Normal Rate is 12-20 respirations per minute

  24. Inspiration vs. Expiration

  25. Let’s practice • Get with a partner within your anatomy group • Practice inspiration vs expiration • Watch each other, make sure that the inspirations and expirations are equal, slow, and controlled.

  26. External vs. Internal • External: exchange of gases between lungs and blood. • Internal: exchange of gases between blood and cells.

  27. Types of breathing • Apnea= without breath • Dyspnea=difficulty breathing • Hyperpnea=breathing >32 times minute • Cheyne-Stokes= series of alternating apnea with hyperpnea

  28. Other Factors • These situations affect the respiratory rate. • Coughing • Hiccups • Sneezing • Yawning

  29. Neural Factors • Respiratory Center • Located in the brain • Involuntary control • Medulla Oblangata

  30. Did we cover?? • Standard 8, Outline basic concepts of normal structure and function of all body systems and explain how homeostasis is maintained. TN Reading 2 • Objective: Describe structure of the respiratory system through lecture and diagrams • Describe the functions of the respiratory system.

  31. Exit Ticket • Use the books and your anatomy groups to answer the questions on the back of the notes sheet. I need to see them before you leave today.

  32. THE END OF RESPIRATORY
