1. Function: Bring in __________________and remove _______________?
2. The nose hairs in the nose filter and _________________the air, keeping it
from drying out?
3. Anatomy and Physiology:The back of the mouth is the
______________________cavity and the back of the nose is the
_____________________cavity?
4. ***KNOW: from the web page and worksheet, the throat has 3 divisions:
place them in the correct sequence from superior to inferior…
____________________, ___________________, and _______________?
5. The ‘food tube’ of digestion is the _______________________which is
inferior to the ‘windpipe’ called the ____________________?
6. ***Know: From the video yesterday and WS, The ‘Windpipe’ has many Cshaped rings made of this type cartilage____________________?
7. The splitting of the trachea into bronchi is called ____________________?
8. The first set of bronchi is called R and L Mainstem bronchi or
_____________bronchi, which branch into __________________and
_________________bronchi, respectively. This whole area as I discussed
yesterday is called the ___________________ __________________?
9. The smallest tubules are called Bronchioles, and at the very end
of them, are tiny air sacs called__________________...THIS IS WHERE
______________EXCHANGE TAKES PLACE***!
10._____________________carry blood away from the heart, and
_______________carry blood to the heart?
11.The _______________ ______________carries deoxygenated blood from
heart to lungs and the __________ _____________carries oxygenated
blood from lungs back to heart?
12. Boyle’s law is the premise for our breathing: P V == constant (K)…so there
is a (equal/ inverse? Relationship between pressure and Volume?
Lung Volumes and Capacities
The following terms describe the various lung (respiratory) volumes:

The tidal volume (TV), about 500 mL, is the amount of air inspired during normal,
relaxed breathing.

The inspiratory reserve volume (IRV), about 3,100 mL, is the additional air that can be
forcibly inhaled after the inspiration of a normal tidal volume.

The expiratory reserve volume (ERV), about 1,200 mL, is the additional air that can be
forcibly exhaled after the expiration of a normal tidal volume.

Residual volume (RV), about 1,200 mL, is the volume of air still remaining in the lungs
after the expiratory reserve volume is exhaled.
Summing specific lung volumes produces the following lung capacities:

The total lung capacity (TLC), about 6,000 mL, is the maximum amount of air that can
fill the lungs (TLC = TV + IRV + ERV + RV).

The vital capacity (VC), about 4,800 mL, is the total amount of air that can be expired
after fully inhaling (VC = TV + IRV + ERV = approximately 80 percent TLC). The value
varies according to age and body size.

The inspiratory capacity (IC), about 3,600 mL, is the maximum amount of air that can
be inspired (IC = TV + IRV).

The functional residual capacity (FRC), about 2,400 mL, is the amount of air
remaining in the lungs after a normal expiration (FRC = RV + ERV).
