Hi, I am having a difficult time with below (A-J &1-2)
A) The mechanical model demonstrates what law?________________________
B) The jar itself represents what body cavity?____________________________
C) The rubber sheet represents what muscle?____________________________
D) The glass tubing represents what part of therespiratory system? ___________________________
E) The balloons represent what organs?_______________________________
F) Pull down the rubber sheet. What happens tothe balloons? ___________________. This represents the downwardmovement of the human _________________, which causes the chestcavity to become ______________________________ (larger/smaller).This, in turn, causes the human ______________________________ toexpand and fill with air.
G) Release the rubber sheet. What happens tothe balloons? ________________. This represents relaxed___________________ (inhaling/exhaling), when the chest cavitybecomes smaller and the lungs deflate. Note that this is a passiveprocess.
H) _______________ Law states that for a givenamount of gas, the pressure is inversely proportional to volumeoccupied. As the volume increases, the gas pressure__________________. The opposite is also true. As volume decreasesthe pressure of the gas _________________.
I) of this principle explains pulmonaryventilation, or breathing. This cycle of breathing consists ofinhalation, also termed _________________ and exhalation, alsotermed ______________.
J) Just before each inhalation, the airpressure inside the lungs equals the pressure of the atmosphere,which is approximately _____mm HG or 1 atmosphere (atm) at sealevel. For air to flow into the lungs, the pressure inside thealveoli must become ____________ than the pressure in theatmosphere.
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 thoraciccavity, the__ contract, pulling the ribs superiorly and the sternum is pushedanteriorly.
2) To increase the space inferiorly, the ____________________,contracts and flattens.
These two steps allow the chest cavity to expand, and increasesthe volume allowing space for the gas molecules, air rushes in andfills the lungs. This activity is _______________________(passiveor active)?
To get air out of the lungs, the volume is decreased because theribs move inferiorly when the
muscles relax and the relaxes and moves back to its dome-like position. This action is_____________.The lungs spring back, the volume decreases, airrushes out this iscalled .
