Definition
| the process by which gases are exchanged between the atmosphere and the lung(alveoli) |
|
|
Term
| The act of breathing in and breathing out is defined as |
|
Definition
| one complete respiratory cycle |
|
|
Term
| Place limewater(calcium hydroxide- CaOH2) in a beaker explain the results |
|
Definition
-becomes cloudy
-Ca(OH)2 + CO2 becomes CaCO3 + H2O
-CaCO3 is insoluble in water |
|
|
Term
| Effect of exercise on CO2 production |
|
Definition
-CO2 + H2O becomes H2CO3(carbonic acid)
-H2CO3 + NaOH becomes NaHCO3 + H2O |
|
|
Term
| Forced Vital Capacity is (test) |
|
Definition
| -the amount of air which can be maximally exhaled following maximal inhalation |
|
|
Term
| Minute Respiratory Volume |
|
Definition
-as the amount of air taken into the lungs in a period of 1 minute
- TV * RR = MRV |
|
|
Term
example of MRV
RR = 12
TV = 500ml |
|
Definition
| 500 ml * 12 Res/min = 6000 ml/min |
|
|
Term
conversions needed to know
in to cm
F to C |
|
Definition
1 in = 2.54 cm
f= 1.8(c)+ 32 |
|
