Worksheet time: 6hrs 4mins
Airways that allow gas exchange are called
respiratory bronchioles
terminal bronchioles
Respiratory bronchioles can be identified by the presence of at least one alveoli along their walls.
true
false

C6
T2
T5

Diaphragm
Internal intercostals
External Intercostals
Which respiratory muscles work during forced expiration?
Diaphragm
Internal intercostals
External intercostals
Suggest two things that happen to the lungs during inhalation (breathing in).
Volume of the lungs decreases
Volume of the lungs increases
Pressure in lungs decreases
Pressure in the lungs increases
Pressure in the lungs remains the same
Suggest two things that happen to the lungs during exhalation (breathing out).
Volume of the lungs decreases
Volume of the lungs increases
Pressure in lungs decreases
Pressure in the lungs increases
Pressure in the lungs remains the same
Suggest one thing that happens to the ribcage during Inhalation (breathing in).
Moves outwards and upwards as the intercostal muscles contract and lengthen
Moves inwards and downwards as intercostal muscles relax
Contracts to become flatter
Relaxes and domes upwards

The total volume of air that can be exhaled during a maximal forced expiration effort.
FVC
FEV1
The volume of air exhaled in the first second under force after a maximal inhalation.
FVC
FEV1
What is the name of the receptors that detect change in blood pH?
Baroreceptors
Chemoreceptors
pH receptors
chemicalreceptors
Which measurement measures the amount of energy in a substance?
Temperature
Volume
Pressure
Mass
Which measurement measures the amount of space a substance takes up?
Temperature
Volume
Pressure
Mass
According to Charles Law, the relationship between Temperature and Volume can best be described as....
Direct Relationship
Inverse Relationship
According to Charles Law, if Temperature of a gas increases Volume will....
Increase
Decrease
Stay the Same
Which Graph best shows the relationship between Temperature and Volume
A
B
Transpulmonary pressure is the difference between the alveolar pressure and the intrapleural pressure in the pleural cavity.
What effect would this have on the alveoli?
it would help to keep the alveoli open
it would promote the collapse of the alveoli
This diagram shows the changes in the alveolus during inspiration. Given what is shown in the diagram, what are two forces that promote the collapse of the alveolus? Click all that apply.
the presence of surfactant in the alveolus
the elastic recoil of the lung tissue
the surface tension in the alveoli
The compliance of a system is defined as the change in volume that occurs per unit change in the pressure of the system. In layman terms, compliance is the ease with which an elastic structure stretches.
Select the correct correlation
as lung compliance increases the amount of muscular work required for ventilation decreases
as lung compliance decreases the amount of muscular work required for ventilation decreases
This diagram shows the relationship between airway resistance and the bronchial tree.
Select the correct correlation.
As airway resistance increases, the amount of muscular work required for ventilation increases
As airway resistance decreases, the amount of muscular work required for ventilation increases

Henry's Law
Boyle's Law
Dalton's Law
