Boyles law

Question 16

The amount of any given gas that will dissolve in a liquid at a given temperature is a fiction of the partial pressure of that gas in contact with the liquid

Answer 16

Henry’s law

Answer 17

Graham’s law

Question 18

Rate of diffusion is proportional to the area of te membrane solubility of the substance in the membrane and inversely proportional to the thickness of the membrane an the square root of the substances MW

Answer 18

Ficks law

What law is linked with factors affecting flow

Answer 19

Poiseuilles law

Question 20

Which flow goes in one direction

Answer 20

Laminar flow

Question 21

What flow is bidirectional

Answer 21

Turbulent flow

Question 22

Answer 22

Exceeds 2000

Question 23

Pressure inside a sphere of liquid of surface tension T is inversely proportional to the radius

Answer 23

LaPlace law

Question 24

Define elasticity

Answer 24

Elastic material is one which returns to its original shape when a distorting force is applied

Question 25

In fibrosing diseases what happens to the lungs

Answer 25

It scars the lungs making them less elastic

Question 26

What happens in emphysema

Answer 26

Makes lungs less elastic by making them floppy and are subject to collapse

Question 27

What does liquid exert

Answer 27

Vapour pressure

Question 28

Name 6 symptoms of respiratory disease

Answer 28

``` Cough Sputum Haemoptysis Breathlessness Wheezing Chest pain ```

Question 29

Name 6 ways to examine respiratory system for disease

Answer 29

``` Finger clubbing Cynanosis Trachea Inspection of the chest Percussion Auscultation ```

Question 30

What is cyanosis

Answer 30

Blue tinge to the skin or mucous membrane due to a lack of oxygen

Question 31

Why do we perform percussion

Answer 31

When we tap the chest we can tell if it is normal or abnormal Normal- filled with air Abnormal- filled with fluid

Question 32

Why do we check the trachea

Answer 32

Check for deviation to one side or the other

Question 33

What does auscultation tell us

Answer 33

Breathing sounds Normal- air quietly moved through the air Wheezing- narrowing airways Crackling- oedema and fibrosis: opening of enclosed airways

Question 34

What do physiologists call breathing

Answer 34

Ventilation
