Chapter 4 lecture 1 untouched

  1. 1. Chapter 4 Skin and Body Membranes Disclaimer: Included in this presentation are pictures you will not find in your book, make note of the information and move on. Working smarter is not working harder.
  2. 2. Something's you didn’t know <ul><li>About 32 million bacteria call every inch of your skin home. </li></ul><ul><ul><li>Germaphobes don’t need to worry however, as a majority of these are entirely harmless and some are even helpful in maintaining a healthy body. </li></ul></ul>Information check… Are you writing this down?
  3. 3. Something's you didn’t know <ul><li>Humans shed and regrow outer skin cells about every 27 days. </li></ul><ul><ul><li>Skin protects your delicate internal organs from the elements and as such, dries and flakes off completely about once a month so that it can maintain its strength. </li></ul></ul>Are you writing this down? Cause you shouldn’t be.
  4. 4. Something's you didn’t know <ul><li>Humans shed about 600,000 particles of skin every hour. </li></ul><ul><ul><li>You may not think much about losing skin if yours isn’t dry or flaky or peeling from a sunburn, but your skin is constantly renewing itself and shedding dead cells. </li></ul></ul>Are you writing this down? Cause you shouldn’t be.
  5. 5. Something's you didn’t know <ul><li>Human lips have a reddish color because of the great concentration of tiny capillaries just below the skin. </li></ul><ul><ul><li>The blood in these capillaries is normally highly oxygenated and therefore quite red. </li></ul></ul>Are you writing this down? Cause you shouldn’t be.
  6. 6. Something's you didn’t know <ul><li>Your body gives off enough heat in 30 minutes to bring half a gallon of water to a boil. </li></ul><ul><ul><li>Ever seen the Matrix? Well the “Machines” were right! </li></ul></ul>Are you writing this down?
  7. 7. Something's you didn’t know <ul><li>Tears and mucus contain an enzyme (lysozyme) that breaks down the cell wall of many bacteria. </li></ul><ul><ul><li>This is to your advantage, as the mucus that lines your nose and throat, as well as the tears that wet your eyes are helping to prevent bacteria from infecting those areas and making you sick. </li></ul></ul>Are you writing this down? … Really?
  8. 8. On with the Show Wake UP!!! The Matrix has YOU!!!!
  9. 9. Classification of Membranes <ul><li>Serous Membranes </li></ul><ul><li>Cutaneous Membranes </li></ul><ul><li>Mucous Membranes </li></ul>3 types of Epithelial Membranes
  10. 10. Epithelial Membranes: Serous Comes in 2’s layers Inside & Outside What’s in-between is called: Serous Fluid A clear fluid that if they could replicate manufacture would replace & change the face of all lubrication on the planet. It’s awesome
  11. 11. Epithelial Membranes: Serous What surrounds the Lungs is called: The Pleura Inside = Visceral Pleura Outside = Parietal Pleura What’s in between the two layers? Serous Fluid
  12. 12. Epithelial Membranes: Serous Peritoneum: the sac covering the internal organs in the abdominal cavity
  13. 13. Epithelial Membranes: Serous What it really looks like… Yummy!
  14. 14. Epithelial Membranes: Serous The bag that surrounds, protects and lubricates the heart. Inside = Epicardium Outside = Parietal Pericardium The Pericardium Lubrication? From what?!?! I’m soo glad you asked!!!
  15. 15. Epithelial Membranes: Serous Imagine the friction created by this action over and over and over and over and over…. you get the idea. So we need the Serous Fluid = Pericardial fluid to do its job.
  16. 16. Epithelial Membranes: Serous Here we see how the Heart and the Lungs articulate and are found in the body.
  17. 17. Epithelial Membranes: Mucous Mucous membranes: line all cavities open to the outside or hollow organs. Include: Respiratory tract: Nose, Mouth, Esophagus and lungs. Digestive tract Urinary tract Reproductive Tract I know…that’s HOT!
  18. 18. Epithelial Membranes: Mucous Mucous membranes: Are considered “wet” due to the mucosae they contain. Ever cough up a fur-ball?
  19. 19. Epithelial Membranes: Cutaneous The Skin!!! The Integumentary System
  20. 20. Epithelial Membranes So what did we cover? Epithelial Membranes: 3 types Serous: Pericardium (Heart), Pleura (Lungs) & Peritoneum (Abdominal Cavity) Mucous: Respiratory, Digestive, Reproductive & Urinary tracts Cutaneous: Skin and other wonders yet to be discovered
  21. 21. Next lecture The Integumentary system and all its wonders
