Respiratory System Mechanical Model - Bell Jar A) The mechanical model demonstrates what law? B) The jar itself represents what body cavity? 2. C) The rubber sheet represents what muscle? _3. D) The glass tubing represents what part of the respiratory system? E) The balloons represent what organs? F) 6. Law states that for a given amount of gas, the pressure is inversely proportional to volume occupied. As the volume increases, the gas pressure 7. The opposite is also true. As the volume decreases, the pressure of the gas would 8. Application of this principle explains pulmonary ventilation, or breathing. This cycle of breathing consists of inhalation, also termed 9. and exhalation, also termed 10. Just before each inhalation, the air pressure inside the lungs equals the pressure of the atmosphere, which is approximately 11 mm HG or 1 atmosphere (atm) at sea level. For air to flow into the lungs, the pressure inside the alveoli must become12. than the pressure in the atmosphere. This condition is achieved by increasing the volume (size) of the lungs by the following steps: 1) To increase the anterior-posterior dimension of the thoracic cavity, the_13_ pulling the ribs superiorly and the sternum is pushed anteriorly. contracts and flattens. 2) To increase the space inferiorly, the 14. These two steps allow the chest cavity to expand, and increases the volume allowing space for the gas molecules, air rushes in and fills the lungs. This activity is 15. active)? (passive To get air out of the lungs, the volume is decreased because the ribs move inferiorly when the 16. muscles relax and the 17. 18. its dome-like position. This action is air rushes out this is called 19. contract, relaxes and moves back to The lungs spring back, the volume decreases, and 21. Forced inspiration requires the use of accessory muscles located in the neck, chest and back. Forced expiration requires the use of 20. muscles. Note - action of the diaphragm is 75% of volume change, external intercostals = 25% eupnea (UP ne uh) - quiet breathing hyperpnea (hi perp NE uh) - forced breathing apnea (AP ne uh) - absence of breathing pnea respiration
