  1. Respiratory System #1

  2. Types of Respiration External: Actual breathing, it is the mechanical way to get oxygen into the lungs Internal: Occurs in the lungs, the exchange of oxygen and CO2 between your alveoli and bloodstream Cellular: occurs inside the muscles, oxygen is used to burn food and carbon dioxide is produced as a waste product

  3. Pharynx more commonly called the throat. It connects the nose and mouth to the rest of the respiratory system.

  4. Tonsils Masses of lymph tissue, that traps and destroys bacteria

  5. Larynx sits on the top of the trachea and contains the vocal cords.

  6. Trachea the tube that extends down from the larynx, through the neck and into the chest.

  7. Pleural Membrane thin layer of skin like material that protects the lungs and keeps moisture in to lubricate for breathing.

  8. Alveoli air sacs found in clusters at the end of each bronchiole. Resembles a bunch of grapes.

  9. Diaphragm muscle that separates the abdomen and chest. Controls breathing.

  10. Lungs 2 sponge-like organs found in the chest. The right lung has three lobes and the left lung has two.

  11. Bronchi 2 tubes at the end of the trachea connecting to each lung. Bronchioles Tiny divisions of the bronchi tubes

  12. Nasal Septum a thin sheet of cartilage and soft bone that divides the nasal cavity into the right and left side

  13. Sinuses air filled cavities in certain facial and cranial bones

  14. Eustachian Tubes tubes that connect the upper throat to the middle ear and help with pressure.

  15. Adenoids masses of lymph tissue on the wall of the nasopharynx. Their function is to trap and destroy bacteria The adenoids are present in all infants and children, and start to regress just before puberty.  They are usually absent in adults.

  16. Epiglottis flap of cartilage that covers the opening of the larynx. The epiglottis keeps food and liquid out of the trachea.
